The park encompasses over 1 million acres (4,000 km2) and includes parts of two mountain ranges (sub-ranges of the Rocky Mountains), over 130 named lakes, more than 1,000 different species of plants, and hundreds of species of animals. This vast pristine ecosystem is the centerpiece of what has been referred to as the "Crown of the Continent Ecosystem", a region of protected land encompassing 16,000 square miles (41,000 km2).
The region that became Glacier National Park was first inhabited by Native Americans. Upon the arrival of European explorers, it was dominated by the Blackfeet in the east and the Flathead in the western regions.
Prior to Skydark, Redoubt Bravo was built complete with a MAT-TRANS gateway. During skydark it was abandoned, and later forgotten except as a local myth. Several attempts met with disaster, until Doc Tanner arrived with the remnant of Trader's convoy. (Pilgrimage to Hell)
