West Glacier to House of Mystery

A community-recommended float starting at West Glacier on the Middle Fork, passing the confluence at Blankenship, and continuing down the mainstem Flathead to a take-out near the House of Mystery on US-2. It overlaps the documented West Glacier to Blankenship Bridge run (Class II, with one Class III rapid at Devil's Elbow) and then mellows onto wide mainstem water. Surfaced from a Flathead paddling group — class, length, flow range, and the exact take-out still need a local verification pass.

Two Medicine North Shore Trailhead RerouteIn 2026, Two Medicine's North Shore Trailhead is not accessible due to construction in the Two Medicine Campground. A reroute has been established to access the North Shore Trail but does require a ford (unbridged water crossing). Directional signage is in place marking the reroute. Hikers may also access Twin Falls, Upper Two Medicine Lake, No Name Lake, and Dawson Pass without a ford, by using the South Shore Trail. Note: this adds approximately 1 mile of distance, one-way.NPS · Information ↗Going-to-the-Sun Road is Open for 2026 SeasonThe Going-to-the-Sun Road is fully open for the 2026 summer season.

Is today the day?

↘
A read for what's actually running — not a generic class description. Updated with every gauge tick.

Good day to go

Flow is sitting in the meaty middle of the best-at range — the band we call fat enough to float, lean enough to read.

At 3,140 CFS this is real whitewater and a confident intermediate day. Strong paddlers with a roll or a reliable wet-exit; helmets and full thermal protection. Scout the big features and keep two boats.

Gut check“Confident intermediate” is a question, not a label: would you be comfortable swimming a rapid this size, in water this cold? If not, that's your answer for today.

  • ✦Scout the crux. Eddy out above the marked rapid and look before you commit.
  • ✦Two boats, minimum. Long runs with no road. You are your own rescue.
  • ✦Helmet, throw bag, whistle on every paddler. Pin kit split between boats.
  • ✦Dress for the swim, not the float — dry layers waiting at the take-out.
  • ✦Tell someone your plan and the time you expect to be off the water.

A long scenic float — West Glacier down through the Middle Fork / North Fork confluence and onto the mainstem. Popular as a SUP and family float.

Read-and-run at most flows — but rivers change. Scoutanything you can't read from upstream, and treat a flaggedportage / scout note below as the minimum, not the whole story.

Put-in

West Glacier

48.4953, -114.0092Directions ↗
Notes
Large cobble-bar take-out off River Bend Drive on river left. Higher-clearance vehicle recommended — passenger cars can bottom out on river cobbles. Heavy outfitter use; parking lot for trailers. Do not park on the beach. Private property adjoins — respect neighbors. Hand-carry craft can also exit upstream at the historic Belton Bridge via a short steep trail.
Take-out

House of Mystery

48.3825, -114.1221Directions ↗
Notes
Informal river-side access on the mainstem Flathead near the Montana Vortex and House of Mystery roadside attraction on US Hwy 2 (7800 US-2 E, Columbia Falls). Sits roughly midway between the Blankenship confluence and Teakettle; works as a shorter take-out for the Blankenship → Teakettle float or as the take-out for the longer West Glacier → House of Mystery combined Middle-Fork-plus-mainstem trip locals run. Not a formal FWP/USFS site — parking limited, exact river access is informal; verify on the ground.

Rules & regulationsvia Flathead Rivers Alliance ↗
  • Personal flotation device. A USCG-approved PFD must be carried on board for every person. Anyone 12 or under must wear a PFD while the vessel is underway.
  • Bear-resistant food storage. IGBC-approved bear-resistant food storage is required in the river corridor — this is grizzly country.
  • Human-waste containment. Self-contained or solid human-waste containment is required on the Middle and North Forks (recommended on the South Fork).
  • Fire management. Fire pans or fire blankets are required or strongly recommended; camp stoves are preferred over campfires.
  • Aquatic-invasive-species inspection. An AIS inspection (NPS and Montana FWP) is required before launching anywhere in the basin.

Safety

LeeRecent report

Mid-May 2026: lots of trees/wood reported in the river and it's running muddy and off-color. Be on your game.

The run

Jimmy11,000 cfsFlow-dependent

Browns Hole at high water (~11k): start left and move right as you enter, avoid the wall on the left, and eddy out to scout — the wave can be as tall as a 14' boat is long.

Conditions

RobertRecent reportsource ↗

Late May 2026, ~6 ft: Cascadilla → West Glacier is tan-green with about 4 ft of visibility. Two non-threatening strainers ~2 miles above where Moccasin/Deerlick Creek enter; obstacles are visible well ahead. Tunnel → West Glacier is fast and semi-smooth, not washed out.

Is it for you

LehiFlow-dependent

Bear Creek runs better at higher flows — high water covers a lot of the rocks so it's less bony.

Andy11,000 cfsFlow-dependent

At high water on the Bear Creek run you want real experience on it and dry suits.

CajunAlways truesource ↗

Locals rate West Glacier to House of Mystery as a standout float — and you don't need a guide for anything below Moccasin.

The original conversations

Hannah asked

Hi crew! Interested in doing Bear Creek to Cascadilla tomorrow. We have run this stretch many times but never at these flows. Looks to be running around 11k. Any advice, intel, words of wisdom?

LeeRan it last year at 11,000 — it's a bunch in places. Depends on your experience. A friend who lives on the river said this morning there are a bunch of trees in the river now and it's muddy.
AndyAt this water level, you should have some experience on that stretch and dry suits if you plan on running it.
JimmyStart left and move right as you enter Browns. It'll be HUGE. You really want to avoid the wall on the left. Definitely worth an eddy-out and scout.
AndrewDrove through the area today coming from the east side. It's pumping and off-color, as expected. Should be fun, but definitely be on your game.
JessicaI wanna run this section, but not right now. Way too much wood in the water.
SamuelDefinitely scout Browns. Last year we ran it at 11k and the wave was about as tall as my 14' boat is long.
LehiBrowns Hole should be a fun wave. I prefer Bear Creek at around those levels — it clears up a lot of the rocks and it's not so bony.
Natasha asked

Looking for some insight. My friend and I come up every year and float on SUP's from HH to Teakettle or Kokanee. We've done Blankenship to Teakettle and HH to Old Steel Bridge before. Those are the only routes we know. Are there any other stretches of the river that you'd recommend? I've done white water rafting a few times and have been paddling the river on my SUP for around 4-5 years. Nothing crazy though, and no training.

CassidyI like middle fork golf course to Blankenship.
CajunYou need to start at West Glacier! Take out at House of Mystery. Best stretch imo.
NatashaHow long? Rapids? Do it with someone knowledgeable first?
CajunYou don't need a guide to do anything below Moccasin.
CajunYes rapids, but nothing crazy.
CajunWest Glacier to Blankenship is a little rougher than Blankenship down, in terms of whitewater.
RoyWhen are you coming? The water level makes a big difference. As Cajun said, consider West Glacier to Blankenship. There is one rapid, Devil's Elbow, worth mentioning. The river makes a big turn to the right. At medium and higher flows the current pushes you into the big rock outcrop. You can totally avoid it by portaging over the gravel bar on the right.
CarmenJust not on a remotely windy day! That last part will blow you backwards up the river!
CajunOh, I should've mentioned that. Always check the wind forecast before getting on the river.
CajunI've paddleboarded Moccasin, but I recommend a helmet and vest for that.
NatashaWe usually come mid-to-late July.
RoyA good time of year for SUP. Unless we just got a bunch of rain, the flow should be on the lower side of moderate. Definitely West Glacier to Blankenship. It'll probably be a good level to play around in Devil's Elbow — carry back up and run it multiple times trying different lines, and practice ferries, eddy turns, and peel-outs at the bottom. Have fun!

Hoping to sneak an overnight float in over Father's Day weekend — ideally a short float you could normally do in a day, camping somewhere along the way. Introducing our small human to river camping; we have technical whitewater experience but want nothing crazy with our passenger.

NatWest Glacier to Blankenship has a few good spots. Columbia Falls to Kalispell also has lots of good spots.
MelodieIt's a great time of year for the North Fork — it gets too low later in the season. Start at the border and finish at Polebridge; get a treat at the bakery. Amazing views.
NateI've had tons of luck doing overnights with very little humans between Teakettle and Presentine. Lots of good spots and a quick float out the next day — the best spots show up with lower water at the end of summer.
