Poston Butte

Poston Butte is a mountain in Pinal County, Arizona, with a summit elevation of 1,749 feet composed of basalt formations overlying altered granite. The terrain features a prominence of 223 feet and is accessible via a marked hiking trail.

Charles Debrille Poston, an advocate for Arizona's territorial status with President Lincoln, built a pyramidal tomb at the summit during the 1800s. This monument marked his significant role in promoting Arizona's recognition at the federal level.

The area shows signs of early Native American settlements and traditional routes that indigenous communities once traveled. These ancient pathways remain visible in the landscape today, telling the story of their long presence in this region.

A marked trail extends 0.6 miles from Hunt Highway to the summit and requires sturdy footwear and water supplies. Visitors should allow adequate time for the climb and be aware of local conditions.

The pyramidal tomb at the peak features inscriptions detailing Poston's work with Native American affairs. This unusual memorial in the desert is a rare example of personal monuments from that era.
