Analysis
The acft was enroute from a powder magazine to a staging area about 2 mi away during a seismic exploration operation. The plt stated that while 100-200 ft AGL he initiated a right turn of 60 deg of bank towards a bowl formed by low lying hills to observe a herd of antelope. The acft encountered a downdraft on the leeward side of the hill causing the acft to settle into sagebrush. The plt estimated his airspeed to be 80 KTS at impact.
