No published club/USHPA wind-window numbers were found for Duffy Mountain (Routt County, CO, ~6,516 ft MSL, west of Steamboat Springs near Hayden in the Yampa valley). The only concrete data is the paraglidingEarth orientation hint that the launch faces/works in the S, SW, W octants. Arc and speeds below are INFERRED from that orientation plus general Rocky Mountain ridge/thermal practice — treat as a rough guess, not a verified site guide. Ideal arc centers on SW (225 deg), spanning roughly S-to-W facing; marginal/cross arc extends to SSE on one edge and WNW on the other, where the wind goes increasingly cross to the slope. As a high-desert Rocky Mountain site, this is almost certainly a thermal/XC launch: expect strong midday thermal cycles, gusty conditions, and possible overdevelopment — morning or evening glass-off and lighter laminar cycles are typically safest, while strong midday wind can exceed paraglider limits. Hazards to assume (unconfirmed): lee-side rotor if wind backs around to N/E quadrants, valley/up-valley wind shifts in the Yampa drainage, terrain-induced turbulence, and venturi acceleration through gaps. Likely a P3/H3+ intermediate-or-better, possibly restricted/permission site — confirm access, current conditions, hazards, and exact wind limits with the local Steamboat Springs club (Storm Peak Hang Gliding & Paragliding / flysteamboat.org) before flying. Coordinates given (40.4258, -107.862) do not match the main Steamboat/Storm Peak launches and were not locatable in club site guides.
