The original Forest Service strip at Monache is said to be unusable. I drove a dune buggy on it a few years back and it seemed smooth enough for 26" tires or bigger, but it had a lot of sage brush on it, so prop clearance could be an issue. However, the runway isn't X'd out - at least it wasn't the last time I was up there two years ago. The East Camp airstrip is privately leased and you have to get permission to land on it, but many don't bother asking. Lots of pilots fly in there to trout fish on the south fork of the Kern. I know a guy who can relay info for permission if you want to keep it legit. I'm gonna be up there in July, so I think I will walk the old public strip to check it out.
Sacatar is also a private restricted airstrip requiring permission to land. You can call the number listed here for permission -

The Tunnel Meadow and Templeton Meadow airstrips are now closed, they were closed when the area they were in became the Golden Trout Wilderness years ago. It's a shame those two closed because the area is amazingly beautiful and generally hard to get to without a lot of walking or a horse. Too bad enough people didn't make enough noise to keep them open.
The Forest Service has a history of being very hostile to any kind of motorized traffic in this part of the Sierras even though the only areas off limits to motorized vehicles are the wilderness areas.
LT, I'll see if I can dig up the lat-longs for East Camp from my GPS for you.
