Here is a map shared by the INF twitter account. I wish it was higher resolution, but you can see the closed areas.
futbol, best bet is to look at CalTopo or other topo map source and figure out where the Wilderness boundary is for the area you are looking at. From what I can tell, the Wilderness boundary is very close to the Horseshoe Meadows TH, and about a mile from the summer homes at the the Meysan Lakes TH.
Ian, thanks for this info!
Maybe our plan C should be Telescope Peak in Death Valley National Park or White Mountain. I will research it.
