No published club/USHPA site guide found for this specific launch; "Bria Dog Ridge (Mammoth Lake)" is primarily a Windfinder spot name (37.705, -118.671, ~8481 ft MSL). Arc inferred from the SW/W/NW orientation hint plus general eastern Sierra / Owens Valley knowledge. Launch faces roughly west, so it works on wind FROM the west: ideal ~240-300 (WSW-W-WNW), marginal/cross edges toward S (~200) and N (~340). HAZARDS: This is classic Owens Valley / eastern Sierra "big air" terrain - some of the strongest thermals and most violent turbulence in the US. Strong prevailing west winds spill over the Sierra crest and create powerful lee-side rotor behind spines and in canyons; mid-day valley thermals and overdevelopment can make conditions unmanageable fast. High-altitude launch (8400+ ft) means thinner air, faster true ground speed, and cold/hypoxia risk on big climbs (climbs to 17-18k ft are common). BEST TIME: smooth early-morning windows before thermals and the west wind build, or the evening glass-off; avoid mid-day (roughly 11:00-16:00) in summer. Keep base wind light (under ~12 mph) and bail if gusts exceed ~18 mph or the wind goes strongly cross/north or backs to the valley (overdevelopment/rotor). RATING/ACCESS: treat as advanced (P4/H4 mentality) - not a beginner site; fly with locals who know the timing. Normal season Memorial Day-Labor Day; spring and fall are mellower. VERIFY locally before flying.
