I was just about to drag this thread back anyway.
Before Steve C's trip, I'd gone to the base of HD to look for the camera and cleanup trash. Both efforts failed - apparently I walked right by the memory card without seeing it, and I had to abandon my two teeming trash bags in the middle of the woods when I was unable to carry them further and they were threatening to split open and dump their contents all over the forest. At some point, I will have to return with some heavier-duty bags and finish hauling them out.
Unfortunately for Steve I managed to make quite the booty call when I was out there, leaving him to scour a field of moldy water bottles for part of a camera and a sleeping bag. The stuff's been sitting in a bag ever since, but I finally got around to taking some pictures:
The intact cell phone and one of the FRS radios was recovered from the ledge below the cables; everything else came from the base.

Bigger files & a few more closeups are available
in my gallery and Steve also copied them to his
Smugmug account so that I could post a few inline w/ my message (the [img] tag requires images to end in .jpg or some such for this site).
Although all 3 cameras (and the lens from camera #4) were all within a 30-foot radius of eachother, I couldn't find a single memory card or camera battery. My best guess is that they separated on impact and took flight. The camera phone I recovered from below the cables did have a memorystick in it, and while I was hoping for spy photos of bikini models, no such luck.
The acute observer will note that while a fishing reel and several cameras were recovered, the reel reported missing by markskor and CaT's camera are both at large. Also, while I don't have any photos (my evidence is somewhere in the hills above LYV), I discovered that while Nalgene bottles are mostly indestructible, the softer plastic caps are subject to a ~50% failure rate when dropped 1000 feet.
One last thing: based on the amount of crap down there, I would recommend wearing a helmet at all times. Personally, I wouldn't get close to the base on a busy summer weekend.
