'''''Pinus aristata''''', the '''Rocky Mountain bristlecone pine''' or '''Colorado bristlecone pine''' is a long-lived species of [[bristlecone pine]] tree native to the United States. It is found in the [[Rocky Mountains]] in Colorado and northern New Mexico, with an isolated population in the [[San Francisco Peaks]] of Arizona. It is found at very high altitudes, from {{convert|2100 to 4000|m|ft|sp=us}} in cold, dry [[subalpine climate]] conditions, often at the [[tree line]], although it also forms extensive closed-canopy stands at somewhat lower elevations.
