No site-specific wind-window data found in authoritative sources. RMHPA/USHPA flying-site list, paraglidingEarth, XContest, and Wilder Adventures' Colorado launch directory have no documented "Bonanza" entry beyond the bare paraglidingEarth marker (orientation hint SE,S). Coordinates place it near the abandoned town of Bonanza, Saguache County, in the San Luis Valley / upper Arkansas region of central Colorado at ~9,656 ft MSL. The ideal arc (125-185, SE through S) and marginal edges (100-210) are INFERRED from the SE,S orientation, not from a guide. Speed/gust ranges are borrowed from the regionally analogous RMHPA Villa Grove guide (~30 mi away in the same valley): paragliders 0-18 mph, ideal ~8 mph, gust factor ~5 mph; hang gliders tolerate to ~25 mph. HIGH-ALTITUDE HAZARDS typical of this region: true wind speed at launch is higher than valley readings; strong/violent thermals and dust devils midday (esp. May-Aug); afternoon thunderstorms and gust fronts; possible lee-side rotor and ridge compression that can strengthen wind and blow gliders over the back. Best windows: morning and evening glass-off in summer, early afternoon in winter; avoid midday in warm months. Thin air at 9,600+ ft means higher true airspeed, longer ground runs/inflations, and reduced margin. Treat as an advanced/XC mountain site (P3+/H3+ recommended); verify direction, access, and current conditions with RMHPA and local pilots before flying.
