They form the southern extension of the Park Range, extending southward from Rabbit Ears Pass (U.S. Highway 40) to the Eagle River and Gore Creek near Vail.

The range forms part of the western boundary of Middle Park at the headwaters of the Colorado, separating it from the upper basin of the Yampa River to the west.

[2][3] The topography of the range is predominantly the result of glacial erosion and deposition during the Pleistocene epoch, forming numerous U-shaped valleys and cirques separated by jagged, sharp ridges aka arêtes.

[2][3][4] The range was named for Sir St George Gore, 8th Baronet, an Irish hunter who visited the area in the 1850s on a notorious hunting expedition throughout the American West.

Wildflowers that may be found in late spring include buttercup, mountain ball cactus, moss campion, Wyoming paintbrush Castilleja and alpine phlox.
