Ask about this camp →U.S. Forest Service lists this site. On most of their ground you can camp away from developed sites pretty much anywhere — so treat this as a known-good spot, not the only one allowed. The unit sets stay limits and how far off road and water you must be. What changes is conditions — roads, gates, closures, fire rules. Check those with the unit before you commit to the drive.

Snow, and when this opens
The nearest automatic snow station is Big Flat at 10,320 ft, about 4 miles away. That is about the height of this camp, so it is a fair proxy. We do not repeat a depth here, because any number we stored would be stale by the time you read it — the station publishes today's.
