About Mammoth Mountaineering Supply
Mammoth Mountaineering Supply is California's premier mountaineering and backcountry ski shop, located at 361 Old Mammoth Road in Mammoth Lakes. With approximately 28 years of operation, the shop has established itself as the Eastern Sierra's go-to resource for alpine touring, telemark, backcountry snowboarding, and splitboarding — gear categories that the resort rental shops largely ignore but that define the soul of skiing in the Sierra Nevada.
As a designated Dynafit Concept Center and North American Competence Centre, Mammoth Mountaineering Supply carries the deepest selection of touring and backcountry equipment in the region, from brands including Black Diamond, Dynafit, Scarpa, Tecnica, La Sportiva, Black Crows, and DPS. Their rental program focuses on backcountry setups — touring skis, splitboards, avalanche safety gear, and crampons — filling a critical niche that the resort-focused shops in town don't cover. The shop also houses the Monkeybar Climbing Gym and a used gear consignment section.
What makes Mammoth Mountaineering Supply irreplaceable is their deep expertise in the specific terrain that surrounds Mammoth Lakes — from Mt. Whitney and the High Sierra to Bishop's climbing areas and Yosemite. Branded as the Telemark Resource of the Eastern Sierra and Eastside Touring Experts, their staff are active mountaineers and backcountry skiers who share route beta, condition reports, and safety advice as part of every equipment conversation. For anyone venturing beyond the resort boundaries, this shop is the essential first stop.
