Landmark Gap is a glacially scoured cut in the mountains that formed during an Ice Age more than 10,000 years ago. The gap was a caribou migration route and a favorite Indian hunting area in centuries past. The Nelchina caribou herd still migrates through this area. The mountain peaks visible through the gap are McGinnis Peak (11,400’) and Mount Moffit (13,020’).
