Mount Charleston: Las Vegas's Cold Lung

Forty miles from the Las Vegas Strip, Spring Mountains National Recreation Area climbs from the desert floor at roughly three thousand feet to the summit of Charleston Peak at eleven thousand nine hundred and eighteen feet. The temperature difference between the valley floor and the summit can reach thirty to forty degrees on a summer afternoon. Las Vegas in July averages over one hundred and five degrees at the base. The forest at eight thousand feet is ponderosa pine and white fir. At the summit, above treeline, it is limestone rock and bristlecone pine, the oldest living trees on Earth.

Spring Mountains is administered as a unit of Humboldt-Toiyabe National Forest and separately branded as a National Recreation Area to acknowledge its specific function: it is the outdoor recreation escape valve for a metropolitan area of two million people with essentially no wild land within its own basin. Las Vegas has mountains on every side, but the Spring Mountains are the only ones close enough and high enough to provide genuine forest and genuine cold within an hour of the city.

The bristlecone pines near Charleston Peak are among the older specimens known in the Great Basin, some estimated at three thousand years or more. Bristlecones grow at or above treeline in the limestone-rich soils of the Great Basin ranges, growing so slowly in the cold and desiccating wind that the wood becomes dense and resistant to rot and insects. They do not so much live long as they refuse to die.

The Nuwuvi, the Southern Paiute people, have lived in and around the Spring Mountains for thousands of years. Their name for the range translates roughly as the land of the sleeping giant. The range is sacred to them. It is also, as of the twenty-first century, the place where Las Vegas goes to cool off.
