WINTER ROUTE, Marble Mountain Sno-Park

Trailhead - Marble Mountain Sno-Park: Snowy conditions from the trailhead to the summit.

Route finding: Do not just follow the "fall-line" on your descent ("fall line" is if you were to roll a ball down the hill, it would travel with gravity and that would take you off-route). Route finding may be challenging, especially in dense cloud or fog; be sure to know the route and carry a map and compass or navigation equipment.

Glissading: Always make sure you can see where you're glissading to. Watch out for exposed rocks.

Forecast: Conditions are highly variable. See the forecast links below. 

Gear: Please be prepared for winter conditions. Microspikes, an ice axe, and the appropriate clothing.

Leave No Trace: Climbers are required to utilize blue bags to pack out all human or pet waste, including toilet paper. 

Camping: There is dispersed camping and pit toilets available at the trailheads, but no running water, and bathroom services may be limited so please bring your own toilet paper, soap, water, or hand sanitizer. Please plan accordingly.
