🏔️ Arbuckle Mountains

The Arbuckle Mountains are an ancient mountain range in south-central Oklahoma in the United States. They lie in Murray, Carter, Pontotoc, and Johnston counties. The granite rocks of the Arbuckles date back to the Precambrian Eon some 1.4 billion years ago which were overlain by rhyolites during the Cambrian Period. The range reaches a height of 1,412 feet above sea level. According to the U.S. Geological Survey (USGS):The Arbuckles contain the most diverse suite of mineral resources in Oklahoma: limestone, dolomite, glass sand, granite, sand and gravel, shale, cement, iron ore, lead, zinc, tar sands, and oil and gas; all these minerals are, or have been, produced commercially.
