The 60-mile-long Wichita Mountains chain runs from the northwest to the southeast in the southwestern part of Oklahoma. The average peaks of the mountain chain reach up to about 1,000 feet.
The highest point of the Wichita Mountains, Haley Peak, reaches to 2,481 feet, followed by the second-highest, Mount Scott, at 2,464 feet. The mountains are primarily composed of granite, rhyolite and gabbro and date back to the Cambrian Period, with subsequent rounding occurring during the Permian Period. Collisions that occurred between the continental plates during the Pennsylvanian Period aided in the mountains' formation. The Wichita Mountains National Wildlife Refuge offers recreational activities and preservation.
