No published wind-window numbers found. Grizzly Mountain (Crook County, near Prineville, ~5,587-5,629 ft MSL, Crooked River caldera welded tuff) is listed by the local club Desert Air Riders as a CLOSED site, shut down per landowner request, so access is currently restricted/prohibited - confirm permission before flying. Arc is inferred from the paraglidingEarth orientation hint (S, SW octants) plus general ridge-soaring knowledge, not from a club site guide. The launch faces roughly south to southwest, so it works best in straight S to SW winds (ideal arc ~180-225 deg). Marginal/cross conditions extend a little into SSE (~157) and WSW (~248); beyond that it becomes too cross or leeside. This is a high-desert thermal environment: midday desert thermals can be strong and "rowdy," with the smoothest air at evening glass-off - similar to nearby Pine Mountain/Pine Ridge sites flown by the same club. Watch for thermal gust cycles, mechanical turbulence/rotor on cross days, and the typical Central Oregon afternoon wind buildup. Suggested speeds (ideal 7-15 mph, base max ~18, gust max ~22) are conservative inferences, not site-verified. Treat all numbers as low confidence and verify with Desert Air Riders before any flight.
