Named for Tom Fitzpatrick, a mountain man and partner of John Bridger, this wilderness area was founded in October 1976, and contains 191,103 acres. The region, once called Glacier Primitive Area, is popular for its many glaciers and mountain peaks. The area covers the N half of the Wind River Mountains and borders the Bridger Wilderness Area to the west and the Wind River Indian Reservation to the east.
Most of the area is carved out of granite and limestone by the action of glacial streams. There are 44 active glaciers in the region, the largest covering 1,220 acres. The highest peak in the state, Gannett Peak, is in the Fitzpatrick. The wilderness area includes canyons, alpine meadows, rock covered plateaus, scenic lakes and cascading streams. Many wild- life species make their home in this region, including elk, mule deer, bighorn sheep, bobcat, coyote and black bear. There are 60 fishing lakes and big game hunting is offered during autumn.
