Hancock (a.k.a. Koosherem Reservoir launch), managed by Central Utah Air Sports Association (CUASA). Coordinates 38°33'32"N 111°48'13"W match the given site; launch elevation ~9,337-9,359 ft MSL, LZ at ~7,000 ft (38°34'04"N 111°50'24"W), ~2,300 ft vertical. WEST-FACING launch confirmed by CUASA Handbook; works best with a westerly component (SW-W-NW), matching the paraglidingEarth octant hint. Ideal arc centered on W (270°), roughly SW(225°)-NW(315°); marginal/cross edges extend a bit beyond (~200°-340°). DIRECTION: a south or north component beyond the marginal arc is cross; any east component is unflyable (blown over the back / leeside). SPEED: high-altitude thermal/XC site (~9.3k ft, thin air) — ideal light-to-moderate westerly thermal cycles ~5-12 mph; max usable base ~15 mph, gusts to ~18 mph before it gets too strong/turbulent for the thin air and tight launch. CUASA's general guidance gives no hard per-site speed numbers and stresses checking with local flyers; the comparable Monroe Peak PG numbers (ideal ~8, max ~12, gust ~3) suggest erring conservative. HAZARDS/ACCESS: excellent thermal and XC launch with a straight shot toward the Fish Lake High Top plateau, but it is a remote, committing mountain site. Access is a mostly 2WD drive-up with the last ~50 yards rougher; launch is a tight slot/short ramp carved in trees (per hang-gliding wiki description). Be alert for strong midday thermals and possible leeside rotor in the LZ if winds back to the east; best in morning-to-midday thermal cycles with a clean westerly. Mountain XC site — intermediate (P3/H3)+ recommended; CUASA + USHPA membership required, helmet and reserve mandatory. Note: a separate "Hancock" hang-gliding site in NY (Southern Tier Skysurfers, rattlesnakes) appears in search results and is NOT this Utah launch — directional/speed data here is for the Utah CUASA site.
