Glacier CountryMontana's Northern Rockies — The Complete Field Guide

Part one: the $1 shuttle

A ticketed pilot for 2026: $1 per person processing fee, everyone aged 2 and up needs a ticket, under-2s ride lap-free. 1 July – 7 September 2026.

• Recreation.gov ONLY — no in-park sales. Arrive without a ticket and no signal, and you have no move. 877-444-6777
• 60-day rolling window from 2 May, 8:00 am MDT — plus a next-day drop at 7:00 pm MDT (from 30 June). The evening drop is the realistic play for anyone who didn't plan two months out
• West: Apgar VC and Lake McDonald Lodge, via the Loop (afternoons only) to Logan Pass. East: St. Mary VC and Rising Sun
• Departures roughly 6–11 am; returns roughly 7:30 am – 7:30 pm (west), 7 am – 8 pm (east), every 60–90 minutes
• NO stop at Avalanche or Trail of the Cedars — new, and it matters. Avalanche is now drive-and-park only, and its lot fills first

Part two: the three-hour cap

Logan Pass parking is capped at 3 hours, 1 July – 7 September — and the part everyone misses: it is in effect 24 hours a day. Not 9-to-5. Not "peak hours." Around the clock.

• Free, no reservation — take a free timestamped permit from a kiosk and display it on the dash. Tape provided for open-tops
• The park's caveat, verbatim: "A parking space at Logan Pass is not guaranteed." The cap governs how long you stay, not whether you get in
• Overnight exemptions: wilderness permit holders whose itinerary starts or ends at Logan Pass, and Granite Park Chalet guests. That's the list
• The penalty for overstaying is not stated by the NPS — so we're not inventing one. Assume it's enforced and don't find out
• NPS says explicitly: Highline hikers must use the shuttle. A 3-hour cap and an 11.8-mile trail are not compatible arithmetic

The size limits — verified, not negotiable

• Longer than 21 ft (6.4 m) including bumpers, or wider than 8 ft (2.4 m) including mirrors: prohibited between Avalanche Creek and Rising Sun. That's the NPS's wording and it's the one to trust
• Over 10 ft (3 m) tall: the NPS says you "may have difficulty" heading west from Logan Pass to the Loop, because of rock overhangs. Note the word — difficulty, not prohibition. We're not upgrading it; the park chose it deliberately
• A sourcing note: recreation.gov describes the restricted stretch as "Sun Point to Avalanche," which is shorter than the NPS version. Use the NPS wording — the longer, more conservative span, from the agency that owns the road
• Logan Pass: 6,646 ft / 2,026 m. Road length: about 50 miles

When it opens, and why you can't count on it

2026: fully open 22 June (NPS release, 23 June) — then closed by the flood on 29 June and reopened 30 June. That's the season you're driving into: opened, shut, opened again, inside nine days.

The pattern: typically fully open by early July, closing the third Monday of October. Recent full openings — 13 July 2020, 25 June 2021, 13 July 2022. Earliest ever: 16 May 1987; latest in that run, 13 July. A mid-July trip is safe on the averages; mid-June is a coin toss with the Big Drift.

One honest correction: you'll read a dramatic depth figure for the Big Drift. We can't verify it anywhere. What is documented is construction engineers facing "sixty foot snow-drifts" (HAER). Use that number, with that attribution, and let the internet keep its eighty.

Routing, decided in advance

• Many Glacier / St. Mary → Chief Mountain, with Carway/Piegan as the fallback when it's shut
• St. Mary / GTSR east portal → Carway/Piegan. It closes at 11 pm
• Whitefish / Kalispell / West Glacier → Roosville — the only 24-hour port serving the west side
• Late, fast, or oversize → Coutts/Sweetgrass. The long way round, and it never closes
• Del Bonita and Wild Horse are short-hours rural ports — don't let a mapping app talk you into one at 6 pm

The time zone that doesn't change

There is no time change at any of these crossings. Alberta and Montana are both Mountain. Drive south, your clock is right.

The one that trips people is Roosville, because it's in British Columbia and BC reads as Pacific. It isn't, there — the Kootenays run on Mountain. A 2026 wrinkle worth knowing: BC moved to permanent daylight time on 8 March 2026, but the Kootenays are carved out and, in the province's own words, "remain aligned with Alberta" (gov.bc.ca, updated 23 March 2026). The region that would have been confusing is the one that stayed the same as home.

Southbound: settled

Canada → USA: permitted. CBP Article 1637 (published 4 November 2025), verbatim: "Bear spray is permitted in the United States when crossing the land border." No EPA condition is attached to travellers in that sentence.

The machinery behind it: bear spray is a pesticide under FIFRA, but the regulation that would bite (40 CFR 152.15) binds a person who "distribute[s] or sell[s]" a pesticide. A traveller with a can on their hip does neither.

One honest wobble: we could not verify that CBP doesn't require an EPA Notice of Arrival (Form 3540-1). 19 CFR 12.112(a) says an importer "must" file one, and no personal-use exemption exists in 19 CFR 12.111–12.114 or 40 CFR 152. In practice nobody is ever asked — but that's practice, not a carve-out, and we won't assert a carve-out that isn't written down.

Northbound: the error everyone else prints

The claim you'll read everywhere, including from CBP and from Glacier National Park itself: "Canadian Customs will allow bear spray approved by the USEPA to enter Canada… must bear USEPA on the label."

Look at what that is. It is a US agency asserting what Canadian customs will accept. We went looking for the Canadian source behind it. There isn't one. No CBSA page and no Health Canada page says an EPA number alone suffices — and read the Canadian rules directly and they appear to say something closer to the opposite.

Inside the park: allowed — but only because the Superintendent said so

This surprises people. 36 CFR 1.4 defines "weapon" to include an "irritant gas device," and 2.4(b)(1) prohibits weapons. Bear spray is legal in Glacier only because the park's Compendium says so. The NPS states plainly that "some parks do not allow the possession or use of bear spray."

Glacier's Compendium (22 June 2026) permits it "for the strict purpose of protecting one's self or others from bodily harm against aggressive wildlife" — and sets specifications: EPA-registered, commercially manufactured, labelled "Bear Spray," 1–2% capsaicin.

The sting in the tail: a Canadian-only can could fail Glacier's own compendium on the EPA-registration point. The dual-registered brand solves both directions at once — which is why we recommend it.

And one that catches people: you may not apply it to equipment or your surroundings as a repellent. Spraying your tent is illegal — and it attracts bears rather than repelling them. It's a deterrent for an animal in front of you, not a perimeter.

Specs, carry, and the thing about backpacks

• IGBC specifications: labelled "for deterring attacks by bears" · 1.0–2.0% capsaicin · ≥225 g / 7.9 oz · EPA-approved
• Belt or chest holster at all times. NEVER in your backpack — the NPS's reasoning is one unanswerable sentence: "you won't be able to reach it."
• It is NOT required in Glacier — recommended only. The NPS says it "has been shown to be the most effective deterrent." Read that as required
• Parks Canada (mod. 28 June 2024), for the Waterton half: "To be legal in Canada, the label must clearly show that it is intended for use on animals; the package volume cannot exceed 500 ml." Carry on hip or chest, check the expiry. Not mandated there either
• Bear bangers are a different story: NOT permitted into Canada (CBP 1637). They're explosives. Don't improvise

The eight you can book

Apgar · Avalanche · Fish Creek · Many Glacier · Rising Sun · Sprague Creek · St. Mary · Two Medicine.

Booking runs mostly on a 6-month window — but "a good handful" of sites are held on a 4-day window. That short window is the late-planner's play: a Glacier trip decided on a Tuesday for the coming weekend is not automatically a lost cause.

At press: Two Medicine Campground is closed (§00). It's on the reservable list, so check before you count on it.

The five that are first-come

Bowman Lake · Cut Bank · Kintla Lake · Logging Creek · Quartz Creek.

Read that against the length table and you'll notice something: every one is capped at 21 feet. The first-come campgrounds are, structurally, the small-rig campgrounds. Driving something long, the spontaneity option isn't really open to you — which pushes you back to the 4-day booking window rather than a hopeful drive up the North Fork.

No hookups. Anywhere.

The park's word is not "unavailable," it's prohibited: "connection to water, sewer, or electrical outlets is prohibited." There is no serviced site in Glacier to be found or negotiated for. Many Glacier has a dump station at the entrance. Plan a dry camp with a tap nearby, because that's what it is.

Generator hours

8–10 am, 12–2 pm, 5–7 pm only. Six hours a day in three blocks. Banned entirely at Sprague Creek and Cut Bank. Quiet hours 10 pm – 6 am. If your fridge and furnace both need power you don't have, do that arithmetic in the driveway, not at 11 pm at Many Glacier.

Stay limits, and the trap

14 days from 1 July to Labor Day; 30 days from Labor Day to 30 June. The detail that catches long-trip people: days combine across visits. Leaving the park and coming back does not reset your clock. It's a seasonal total, not a per-stay allowance.

The actual inventory

• 80 glaciers over 0.1 km² at the Little Ice Age maximum, around 1850 — mapped from their moraines
• 32 in 2005 — roughly a 60% decline from 1850
• 26 meeting the criteria in 2015. 37 named glaciers exist; 26 still qualify
• Mean area loss 39%, 1966–2015/16. Worst individual: Boulder, at 85%
• Released May 2017; survey years 1966 / 1998 / 2005 / 2015–16; 39 glaciers studied (37 in the park, 2 on Forest Service land)

The work behind it: Dr. Daniel Fagre (USGS), Andrew Fountain (Portland State), and Lisa McKeon, whose repeat photography has run since 1997 — the reason you can see the change rather than read about it.

Where "150" came from: nowhere

We went looking for a source. There is no USGS or NPS source for "150 glaciers in 1850." Not a stale one, not a superseded one — none we could find at all. It has propagated for decades on its own momentum.

Which is the actual story, and it's a bleak little one: the myth is more famous than the measurement. USGS mapped the moraines, counted 80, published it — and the unsourced number is still the one on the postcards. The real figures don't need inflating. Sixty percent gone by 2005 is not a statistic that requires help.

What the park stopped saying

For years the signs said the glaciers would be gone by 2020, then 2030. The NPS removed that signage in 2019. The current line is a model of earned humility: "though the glaciers are melting, when they will be gone is uncertain."

USGS modeling still "predicts near total… disappearance by 2100" — with real caveats about ice thickness, shading and wind. Both statements are true at once. The park was wrong about the date and right about the direction, and it changed its signs rather than defend them. That's more interesting than either side's version.

Go and see one

• Jackson Glacier — from the overlook 5 miles east of Logan Pass. From your car. The answer for anyone who can't do a hard day, and nobody tells you it exists
• The Salamander — from the road driving into Many Glacier. Also from the car
• Grinnell — the famous one, a real day's work (§11)
• Sperry — 8.5 mi / +5,000 ft, or a distant smudge from Hidden Lake Overlook with binoculars
• Best timing: late August to early September. Once the winter snow is gone you're looking at ice. Before that you're looking at last winter and calling it a glacier

The Peace Park, dated

• 1932 — the world's first International Peace Park
• Waterton: Canada's 4th national park, 1895 · Glacier: the 10th US national park, 11 May 1910
• UNESCO, 6 December 1995 — a single property, #354. One World Heritage site. Two countries. Two of our issues (004 and 008). Not a marketing line; it's the inscription

Two things we won't print: the Rotary origin story for the Peace Park is unverified — the NPS page doesn't mention it — and we could not confirm the year of the Biosphere Reserve designation. Both widely repeated. Neither in a source we could stand behind.

The switchback argument

August 1924. The 1918 Goodwin plans called for 15 switchbacks up the west side. Tom Vint argued for a route with one. Mather and Kraebel came to inspect; Vint and Goodwin argued their cases at him; and then — the part worth the price of the issue — Mather glanced at their horses, turned, and stormed off. Vint and Goodwin never caught him.

Two days later Mather handed the survey to Kittredge. Vint's plan had won. He never said so — he just walked away and gave the job to the man who'd build it Vint's way.

Today there is exactly one switchback west of the Divide. It's called the Loop. You'll stand in it waiting for an afternoon shuttle off the Highline, and now you'll know why it's the only one.

The name — and the NPS prints both versions

Named for Going-to-the-Sun Mountain. The legend, carried in a 1933 Interior press release: the deity Sour Spirit came down from the sun to teach the Blackfeet to hunt, and left his image on the peak on the way back up.

And then the NPS itself notes the alternative: that "a white explorer in the 1880s concocted the name and the legend."

The Park Service does not adjudicate. It prints both. So do we — because the honest position on a hundred-year-old story about whose story it is, is that nobody knows, and the agency closest to it has declined to pretend otherwise.

The dedication, 15 July 1933

Four thousand people on Logan Pass. A CCC chorus. The Blackfeet Tribal Band played the Star-Spangled Banner.

The afternoon ended with a ceremony of peace among the Blackfeet, Flathead and Kootenai.

Thirty-eight years after the United States acquired the mountains those people were standing on, from one of the nations standing there. Read the next box, then come back to this one.

Night of the Grizzlies — 13 August 1967

Two 19-year-old women killed by grizzlies in separate attacks about ten miles apart, the same night. Julie Helgeson, of Albert Lea, Minnesota, near Granite Park Chalet. Michele Koons, of San Diego, at Trout Lake. There was lightning that night. Until then, nobody had ever been killed by a grizzly in this park.

Two, ten miles apart, in one night is not coincidence — and the park knew why almost immediately. Four days earlier, on 9 August, rangers filed a report on bears feeding on garbage from Granite Park Chalet. A 1966 gas incinerator was undersized, and the caretaker had resumed dumping garbage in the gully.

These were garbage-habituated bears. The park fed them. That is the sentence the modern rulebook was written around.

Sources: Jack Olsen, Night of the Grizzlies (1969) · Smithsonian · MontanaPBS. Not Wikipedia.

What that night built

1967 drove the first modern bear management anywhere. Look at the list, then look at your campsite:

• Bear-proof garbage cans
• Separating cooking areas from sleeping areas
• Wire food-hang cables
• A permit system to track and limit backcountry campers — the one you'll queue for in §10

Every one is now standard from Alaska to Alberta. The bins in your Kananaskis campground, the hang cable at a Banff backcountry site, the 10-foot rule you'll follow on the Flathead this week — all of it starts at Granite Park Chalet on 13 August 1967.

So when the food-storage order reads like officious nonsense at 11 pm: it isn't bureaucracy. It's a memorial with a fine attached.

Dogs: banned on all trails

Not restricted. Not leashed-only. Banned. On every trail in the park. If your mental model is Kananaskis, delete it.

Allowed: in cars on park roads, in frontcountry campgrounds, picnic areas, along roads when stopped, parking areas, and boats where motorized craft are permitted. Not allowed: trails, lake shores outside developed locations, backcountry, any building. Leash: 6 ft max. One exception parkwide: the Apgar–West Glacier bike path, when snow-free.

Heat: the NPS's arithmetic — 80°F outside becomes over 94°F in a closed vehicle in two minutes, over 120°F within an hour. Glacier "frequently sees days well in excess of 90 degrees." Kennels in the Flathead Valley; Jewel Basin (§12) is the leashed-dog answer.

Fishing: no licence needed

Verified, unusual, worth printing in bold: no licence is required to fish inside Glacier National Park. You just go.

• Season: third Saturday in May – 30 November. Lake fishing open all year
• All native fish must be released
• No daily or possession limit on non-native species — the park wants them gone and you're welcome to help
• Artificial flies and lures only in most areas
• The boundary catch: Lower Two Medicine Lake limits are set by the Blackfeet Nation

Drones: prohibited

2026 compendium, via servicewide Policy Memorandum 14-05 (June 2014). One nuance: PM 14-05 was an interim measure. Twelve years on it's still the mechanism, enforced through each park's compendium — so "banned in all national parks" is true in effect, but it's roughly 400 individual closures rather than one rule. Practically: leave it home.

No dispersed camping

Camping is by permit at designated sites. Phrased that way deliberately: we could not find the explicit words "dispersed camping is prohibited" on an NPS page, so we won't put them in quotation marks. The effect is the same — nowhere to legally pull off and sleep. The free version is next door (§09), and the permit system exists because of 1967 (§15).

Firearms, briefly

Short and conservative, because the sources are a mess. CBP Art. 1204 says all non-immigrants — including those admitted without a visa — must apply for an ATF permit via Form 6NIA. "Self-defence" is not an available basis — 27 CFR 478.115(d)(1) allows only "legitimate hunting or lawful sporting purposes," and it must go back out.

Hospitals — and the one nobody tells you about

• Logan Health Medical Center, Kalispell — 24/7 ER, ACS-verified Level III trauma with neurosurgery (note: not Level II, whatever you read). 406-752-5111; ER 406-752-1733. Address conflict — we print both: 350 Conway Dr (Logan's ER page) / 310 Sunnyview Ln (Medicare/AHD). Same campus; Conway is likely the ER entrance
• Logan Health–Whitefish, 1600 Hospital Way, 406-863-3528 — 24/7 ER (formerly North Valley Hospital, merged June 2021)
• Blackfeet Community Hospital, Browning (IHS) — 28 beds, 12-bay ER, helipad. 760 Hospital Circle, 406-338-6100. Nearest to St. Mary, Babb and East Glacier — though its 24/7 status is not stated on the IHS page
• Cardston Health Centre, Alberta (AHS) — 24/7 ER. 144 2 St W, 403-653-5234. The nearest Canadian hospital, via Chief Mountain

Rebrand warning: still officially Logan Health as of July 2026, now under Billings Clinic-Logan Health post-merger. A full rebrand is slated to conclude in 2026 but has not been announced — signage may change mid-season.

Money, and the pump that holds your card hostage

• USD only. Interac does NOT work in the US — Canadian debit falls back to Visa Debit / PLUS / Cirrus
• Canadian FX fee ~2.5% (CIBC, credit and Visa Debit). ATMs stack operator + foreign ATM + FX — call it ~3.5%. Some cards waive FX entirely: a pre-trip action item, not trivia
• THE ONE THAT HURTS: gas-pump pre-authorisation holds can take DAYS to clear on a foreign card. PAY INSIDE. Hold amounts vary and we're not printing a figure, but the mechanism is real and it can strand a family's float mid-trip
• And the park takes no cash (§03). Card at the gate, cash nowhere

Speed: Montana has a day/night split

Albertans don't expect this and it's real law — MCA 61-8-303, amended 2025. The limit changes at dusk.

• Interstate outside urbanized areas: 80 mph day & night (65 in Billings, Great Falls, Missoula) ≈ 129 km/h
• Four-lane national highway: 75 day / 70 night
• All other public highways — US-2, US-89, MT-49, MT-17: 70 day / 65 night ≈ 113 / 105 km/h. These are your roads
• Urban: 25 ≈ 40 km/h. "Daytime" = half an hour before sunrise to half an hour after sunset. The statute permits +10 mph to overtake on a two-lane

Posted limits override all of this. And Going-to-the-Sun Road is far slower — statutory limits are irrelevant in the park. You'll be doing 25 and grateful.

Connectivity: assume none

NPS, verbatim: "Most visitors will find cell reception in West Glacier up to Apgar Village. There is limited coverage in St. Mary." That's the whole coverage map. Expect NO signal: Many Glacier, Two Medicine, Logan Pass, North Fork, Goat Haunt, the backcountry, southern US-2. Public WiFi at exactly two places: the Apgar and St. Mary visitor centers. (That NPS page was last updated December 2021 — stale, but the terrain hasn't moved.)

Roaming: Rogers $16.00/day (now including satellite-to-mobile in the US; cap not stated) · Telus Easy Roam $14/day + tax, up from $12 in Oct 2025, ~$280/cycle ≈ 20 days (medium confidence — telus.com 403'd us; phone-verify) · Bell Roam Better $13/day, 20 days/cycle (~$260) then free, unlimited calls and texts in the US and to Canada, uses your plan's data, throttled to 512 Kbps after 5 GB/day, charged only on days used — and the day ends 11:59 pm ET regardless of your time zone. Rogers Travel Passes ($25–$80, 3/7/14/30-day) beat $16/day for a week-plus trip.

eSIM pricing is all comparison-site sourced and unverified: Airalo ~5 GB ≈ $24 USD, unlimited 30-day ≈ $61.50; Nomad free 1 GB/3-day trial, 20 GB/30 d ≈ $18, unlimited 20 d ≈ $49 (AT&T + T-Mobile). The honest caveat: an eSIM is a DATA plan. It won't ring your Canadian number, and it doesn't help where there's no tower — which is most of this park. Three-day trip: day passes. Ten days: eSIM wins.

Unverified but useful: Verizon is much better on the east side; AT&T near-nothing until East Glacier. Telus and Bell typically land on Verizon, Rogers on AT&T/T-Mobile — so east-side Telus and Bell users may fare better than Rogers users. Carriers don't publish partner mapping; treat it as a working theory.

What to physically carry

• Alberta pink card · registration · passport or NEXUS
• Valid Alberta licence — the physical card
• If it's not your vehicle: a letter of permission from the owner plus confirmation you're a listed driver

Dogs across the border — the two countries want different things

Into the US (Canada is low-risk; the CDC high-risk list of 15 April 2026 excludes Canada). Rules effective 1 August 2024:

• CDC Dog Import Form receipt — the ONLY required document. Online, FREE. Valid 6 months and reusable — the CDC uses Canada as its own example
• Healthy · at least 6 months old · microchipped · any land crossing
• NO rabies certificate required by the CDC for a Canada-only dog

Back into Canada (CFIA Import Reference Document, amended 8 October 2025 — binding). The US is not rabies-free, so a dog 8 months or older needs (a) a valid rabies certificate in English or French from a licensed vet, or (b) an RNATT titre ≥0.5 IU/ml, or (c) inspector-ordered vaccination at your expense. No quarantine. Under 3 months: no certificate. Assistance dogs: no restrictions. Canada does not require a microchip.
