Takeoff description
The 750' launch (~2500ft MSL) is so named because it is 750ft vertically above the Andy Jackson Airpark LZ (same typical LZ as Marshall). It is a less popular alternative to the Marshall launch but has some key advantages: (1) It is readily accessible from Andy Jackson via the dirt 2N40 forest service road (~10 min, moderate clearance recommended) or a 0.6mi hike on a foottrail (~30min, steep). (2) Being lower elevation, cloud cover is less of an issue than at Marshall. (3) The quick access and quick flights in non-thermic conditions are well suited for beginners (and others) to rack up a large number of flights in a short time frame (such as four flights before noon). (4) On particularly thermic days it is possible for a launch from 750' to gain altitude up to and in excess of Marshall, defeating the need for a shuttle. Hanggliders do not seem to use this launch. The launch is a 50'x80' dirt and gravel patch sloping SSW at the south end of the large pull out. A streamer on a pole gives some indication of wind. The launch area is less forgiving than Marshall (but again suited for beginners). Non-thermic flights are about 3-4min to AJX. Site is maintained by the Crestline Soaring Society.
