Henninger Flats - No Safe Local LZ

• Wind directionS (180°) → WSW (247°)
• Ideal speed6–12 mph
• Upper limits≤ 15 mph base · gusts ≤ 18

San Gabriel front-range launch above Eaton Canyon / Mount Wilson Toll Road near Pasadena (~2,467 ft MSL). No club or USHPA chapter site guide publishes explicit numbers for this launch; it appears only as a paraglidingmap.com / paraglidingearth entry ("Henninger Flats - No Safe Local LZ"). Wind window is inferred from the paraglidingEarth orientation hint (SE, S, SW, W) plus general SoCal front-range knowledge. The launch faces roughly SSW over the LA basin, so it works best on a south-to-WSW anabatic/onshore flow centered on SSW (~202 deg); SE and W are the cross/edge limits. As an inland thermal/soaring site (not a coastal ridge) it favors light-to-moderate wind: stronger flow off the steep front range produces lee-side rotor and turbulence, so keep base speed modest and avoid gusty/strong conditions. DEFINING HAZARD per the site name: NO SAFE LOCAL LZ — pilots must glide well out into the canyon/basin to reach landable terrain; this is an advanced/committing site. Additional notes: Mount Wilson area has heavy helicopter/aircraft traffic and changeable airspace; Henninger Flats facilities were burned in the 2025 Eaton Fire, so ground access/conditions may have changed — verify current access and TFRs before flying. Best flown mid-day to afternoon on a stable, light SSW day. Speeds/gust caps are estimates, not club-verified.
