The pilot of the tailwheel-equipped airplane reported that, while landing uphill at an off-airport unimproved landing site where he had landed before, he applied the brakes, and that the airplane then hit a "bush or a bump," which caused the tail to rise. Subsequently, the propeller struck the ground, and the airplane nosed over.

The airplane sustained substantial damage to the empennage, fuselage, and wing spars.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
