The Quartz Mountains are an extension of the Wichita Mountains in the far southwestern part of the state of Oklahoma. According to the Encyclopedia of Oklahoma History and Culture, the range was originally formed about 550 million years ago as a "failed continental rift". It was uplifted about 300 million years ago and has since weathered into its current condition. The unique geography provides cover for the most northerly population of live oak, quercus fusiformis. This rare oak is generally regarded as the most cold hardy evergreen oak.General descriptionThe section extends west and northwest of the main Wichita range,separated by a plain dotted with smaller foothills. It is about 13miles east of Mangum and 20miles north of Altus. The tallest mountain in the range is Quartz Mountain at 1887 feet above sea level. The area is popular for rockclimbing on its weathered granite outcroppings and is home to Quartz Mountain State Park and Lake Altus-Lugert reservoir.HistoryFormerly controlled by Spain, France, Mexico, and the Republic of Texas,In the mid 19th Century, these mountains were part of the United States area known as the Leased District and Indian Territory. Old Greer County and the Kiowa-Comanche-Apache Reservation were created from this district and became part of Oklahoma Territory. Actually, the area was mostly controlled by nomadic Native American tribes, until they were militarily pushed onto reservations.
