Needle Peak

Needle Peak is the local name for the Sierra Aguja in Brewster County, far West Texas, near the Mexican border and just west of Big Bend National Park. The name refers to a small mountain range rather than a single summit, and it is distinct from another Needle Peak in nearby Presidio County. Its slopes are known for quartz crystals and lapidary materials such as green moss agate, botryoidal geodes, sagenite, and pompom agates. Those mineral deposits are the feature most closely associated with the local name, giving the range a small but distinct place in the geology-minded landscape around Big Bend.
