About This Route
The West Rim Trail, Zion's premier highline from Grotto to Lava Point (10 miles one-way), transforms into an expert snowboard traverse in deep snow years. Drop bowls off Cabin Spring ridge (1,000 ft vert), link to Phone Canyon chutes. Access via Angels Landing chain section (icy, poles essential); expect 12-18" base from regional storms like Ski Utah's southern powder days. Stunning overlooks of Zion Canyon; camp at Potato Hollow with permit.
Safety Considerations
Exposed ridges amplify winds to 50 mph, scouring powder into sastrugi; anchor gear per REI alpine tips. Knife-edge drops mirror Angels Landing fatalities; rope exposed sections. Flash freeze-thaw cycles create boilerplate ice; crampons for bootpack. Group check-ins every hour; no cell service, carry SPOT. Obey NPS trail etiquette: no sliding on maintained paths to prevent erosion.
Essential Gear
Jones Flagship freeride board; Arc'teryx Gore-Tex bibs; BCA Tracker beacon; MSR snowshoes for low snow; Jetboil stove; bivy sack; maps of West Rim (Nat Geo Trails Illustrated).
