2024 Map of Union Peak

About this map

The Missoula and Granite county line bisects this mountainous stretch of the Garnet Range, where the terrain is marked by steep ridges and narrow gulches. Coloma and Sand Park represent the primary settlements in this high-elevation landscape, situated near the headwaters of several drainage systems. Historically, this area was defined by its mineral wealth and the rugged infrastructure required to extract it, evidenced by landmarks like Copper Cliff and the local Sand Park Cem. The water network is intricate, with Union Creek and Cramer Creek cutting through the slopes, while smaller features like Southern Cross Spring provided essential resources for those living in the upper reaches of the mountains.
