Mammoth Unbound Series Slopestyle 1 - 2027

About this event

Mammoth Mountain opens the January portion of its 2026/27 USASA Unbound Series with Slopestyle 1 on Sunday, January 3, 2027, from 8:30 AM to 4:30 PM. Mammoth describes this as a beginner-friendly slopestyle competition with terrain-park features built for progression and fun, while the series page welcomes skiers and snowboarders of all ages and skill levels. Competitors need current USASA membership, an underlying US Ski & Snowboard membership and active health insurance. The $82.50 event entry is separate from required lift access; registered athletes can email the series contact with registration verification for a race-lift-ticket purchase link. Under the published two-day rule, registration should close January 1, unless capacity is reached sooner. Capacity is not stated; an early sellout triggers a waitlist, and riders are charged only after admission. Late entries are not accepted, and no on-site signup is promised. Public LiveHeats currently shows only completed prior-season events, so TrickBook marks entry not yet open rather than closed. Exact course/park, practice, division order, judging and medal time remain TBA. Check-in is by Zoom the night before, with the link and bib-collection instructions posted in the official Team App; start lists, results and weather changes also flow through Team App and LiveHeats. The event is located in Mammoth's Unbound Terrain Parks, with Main Lodge at 10001 Minaret Road as the published address anchor. Winter parking is free where signed and first come, and free resort/town shuttles normally serve Main Lodge subject to conditions. Helmets are mandatory for all competitors, and a valid lift ticket or season pass is required. The listing uses the narrow Mammoth regional exception because this official USASA National Championships qualifier offers on-snow slopestyle terrain unavailable in core Los Angeles.
