SMOOTHINGIRON MOUNTAIN. Smoothingiron Mountain, also known as Iron Mountain, stands four miles west of the town of Valley Spring in northwestern Llano County (at 30°51' N, 98°54' W). It is the location of perhaps the largest iron ore deposit in the state. Although not the foundation for a significant Texas iron industry that some promoters had anticipated, this deposit has been mined several times, most recently in the 1930s. At an elevation of 1,839 feet, the mountain rises approximately 520 feet above nearby Cold Creek. Local topography is flat to rolling, with local escarpments, and covered with sandy and clay loams. Vegetation consists primarily of open stands of live oak and mesquite.
