It is not intended to get you to any dig sites. Roads are iffy in this entire area. These roads are all very sandy and I bet they are impassable when wet. They are very steep in places. Stick to the main roads when in doubt.
Some areas are off-limits to vehicles to protect sensitive plants.
You can camp up here or back on 243 . A very large log in a pit just down the hill from the radar tower. We got 2 buckets of smaller limbs from this pit as well. Plan to spend some time mucking out a pit for yourself. People have been killed by digging caves here.
