I don't know about a tight seal to the ground without a footprint. Pile some sow on it or make a little sod cloth I suppose.
When we can get tags, which we did this year [second season spike only] we hunt Sled Springs.
It is adjacent to your hunt in the Eagle Caps. Are you entering the Eagle Caps through the Lostine River-Allen Canyon access point?
Good Luck,
Gary
