Pitamakan Pass

Overview

Pitamakan Pass is the big-mountain payoff in the Two Medicine area: a hard, rewarding out-and-back to a high, wind-swept saddle with sweeping views over Oldman Lake and broad glacial valleys. Expect a full-day effort—roughly 14.8 miles round-trip with about 2,746 feet of gain—and a serious alpine feel near the top.

What You’ll See

The approach climbs from forest and meadows to turquoise lakes and banded cliffs, with constant views of peaks like Flinsch and Morgan. Above Oldman Lake the trail steepens and narrows on a rocky ledge before topping out at the pass (around 7,549 feet). Summer brings wildflowers, and you’ve got a real shot at spotting bighorn sheep or mountain goats; moose and grizzlies are also reported in this country.

Trail Experience & Difficulty

Most of the elevation is gradual until the final ascent, which can feel exposed and is known for strong winds. Early season snow often lingers near and above the pass, and conditions can be cold and gusty any time of year. This is an advanced day hike; plan 7–8 hours for the out-and-back, more if you like to linger at the lakes or the pass.

Safety Essentials

Carry layers for wind and cold, plenty of calories, and 2–3+ liters of water capacity. Trekking poles help on the scree and the narrow ledge below the pass—turn around if wind or footing feels sketchy. This is prime grizzly habitat: carry bear spray, make noise in brushy sections, and give all wildlife distance.

Logistics & Amenities

Start from the North Shore Trailhead inside the Two Medicine Campground. When the campground is open, you’ll find flush toilets and potable water there. On trail, there are no facilities; the Oldman Lake backcountry campground has a pit toilet, but plan to pack out all trash. There’s no treated water along the route—fill up at the trailhead and filter from natural sources if needed.

Make It a Loop (Optional)

Strong hikers often connect Pitamakan Pass to Dawson Pass for an 18.8-mile loop that traverses an airy ridge with huge drop-offs and nonstop views. There’s no reliable water on the high traverse—top off at Oldman or No Name Lakes. Depending on schedules, the Two Medicine boat can shave some miles and time.

History & Geology

The pass honors Pitamakan (Running Eagle), a renowned Blackfeet woman warrior. The route has long served as a corridor through the mountains, with a recorded crossing in 1853 during an early (misguided) railroad search. The scenery you’re walking through is classic Glacier: ancient Belt Supergroup sedimentary layers shoved east by the Lewis Overthrust, and valleys, cirques, and hanging lakes carved by Ice Age glaciers.

Best Time to Visit

Late July through September offers the best chance at snow-free travel, though winds are common year-round. From July 1 to September 10, vehicle reservations are typically required to access Two Medicine between 6 am and 3 pm. Start early for parking, calmer winds, and softer light for photos.
