I know, anathema to SP, but that's how I got to the parking lot. Regardless, I have a GPS track to the top (.gpx file). There are actually quite a few places to get confused and make a wrong turn, which I'd really hate to do when hiking. The .gpx file actually includes a larger trip I spent filming in nearby Anza-Borrego Desert SP, but if you'd like a copy of it, message me an e-mail address. I could also drop it into Google Earth and upload that image to SP, attached to this page. I do have a lot of photos and video of the trip, but it's about driving to the top, not hiking. You may view it here, if you think it would be useful somehow ...
