About
Open for now but there is no safe LZ available at the moment. Anywhere that looks good is off-limits due to private property and would jeopardize the site. XC flying is the best bet to find a safe LZ. Please message a local before flying this site to get the low down (https://www.socalxcleague.com/ Aaron Price) Take-off can be found on the trail up to Henninger flats out of the Eaton Canyon Wash. As you are nearing the campground, you will be on a last leg of the trail heading West-ish. As you enter this leg there will be a small power line going up the ridge that you will cross underneath, about 40 yards past this you will see a steep dirt path that leads up about 10' to a grassier slope, this is your launch. There is one tree which divides the launch between a South launch and a West launch so choose carefully which was you want to launch, depending on the cycle it can blow both ways.

Wash LZ
Wash is in bad shape and all other areas are private property. Land in the wash below, the further out from the canyon you fly the sandier and more open it gets. I've found that doing figure eights at the far end of the wash where it turns to run into the dam area (over the high transmission lines) works well then you have plenty of options for a final leg. This works best for West wind days, south days may be trickier. Since the wash is below the house line there will be a gradient and expect lots of sink in the last 20' - 30'. Also make sure to know where the water is flowing in advance sometimes it's not always clear from the air. Do not land at any of the playing fields in Altadena as that is strictly prohibited.
