Aware of current windloading and PWL, chose to ride low-angle glades, just south of Eyrie Peak. Attempted to avoid a small concave roller I was aware was over 30 degrees, but ended up riding through the middle of it triggering a small, inconsequential avalanche. Was not knocked off of board and stopped for observation. Served as a helpful test slope, indicating reactive windslabs on N/NE faces over 30 degrees. Alerted Nordic Valley Ski Patrol upon re-entering ski boundary.
