Aircraft Aircraft Damaged
Environment - Non Weather Related; Procedure
I was approaching Runway 29 at GJT for a full stop landing. A military transport was ahead of me doing touch and go's.  The Tower advised caution wake turbulence. The military transport was off the runway turning crosswind. I was about 8-10' AGL when the airplane made a rapid un-commanded yaw to the left and the right wing dropped.  The airplane hit the dirt between Runway 29 and taxiway A; then bounced on the nose and came to rest on taxiway A on the main gear and nose.
Carbon Cub pilot reported a ground strike occurred following a wake turbulence encounter with a military transport just before landing at GJT.
