About This Route
The Desolation Wilderness section of the Pacific Crest Trail, accessed via Echo Lake from Highway 50 near South Lake Tahoe, California, offers stunning snowshoeing opportunities amid granite peaks and alpine lakes. This popular 10-12 mile out-and-back route follows the PCT from Echo Lake to Tamarack Lake, gaining about 1,500 feet in elevation through deep snowfields typical from November to May. Managed by the USDA Forest Service, it draws winter adventurers for its dramatic scenery, including views of Pyramid Peak and Aloha Lake, but demands respect for its remote, high-elevation terrain above 8,000 feet.
Safety Considerations
Snowshoeing here aligns with National Park Service (NPS) winter travel guidelines: always check the Sierra Avalanche Center forecast, as slab avalanches are common on northeast-facing slopes near Velma Lakes. Hypothermia risks spike in sub-zero temps and whiteout conditions; postholing without snowshoes can exhaust you quickly in 4-8 feet of powder. Follow Leave No Trace by camping 100 feet from water and trails. Real-world scenario: in 2019, a group near Susie Lake triggered a size 2 avalanche, underscoring the need for beacon training per REI expert advice. Navigation fails without GPS; cell service is spotty, so preload Gaia GPS maps of the PCT corridor.
Essential Gear
Pack MSR Evo Ascent snowshoes for superior flotation on crusty Sierra snow, Black Diamond avalanche transceiver, probe, and shovel kit. Add Kahtoola microspikes for icy traverses, a Petzl ice axe for 30-40 degree slopes, and layered clothing like Arc'teryx Gore-Tex shell over Patagonia nano puff insulation. Essentials include a 30L Osprey Talon pack with 2,000-calorie snacks, water filter, and SPOT satellite messenger for emergencies beyond Tahoe basin heli-range.
Emergency Tips
If avalanched, deploy airbag if equipped; otherwise, swim and deploy beacon immediately. For hypothermia, seek shelter in snow cave, share body heat, hydrate with warm fluids. Lost? Dig snow bench, signal with whistle three times hourly, activate PLB pointing south toward Echo Lake trailhead rescue cache.
