East Helena

Location and History

East Helena is located just to the east of Helena, and it has been historically tied to the mining industry, particularly the smelting of silver and lead. Founded in the late 19th century, East Helena developed as a support town for the nearby mining operations in the Elkhorn Mountains and Prickly Pear Valley. The town grew rapidly after the establishment of the East Helena Smelter in 1888, which processed ores from the area’s mines. The smelter was one of the largest in the region and played a significant role in the development of East Helena. However, by the mid-20th century, mining operations in the area began to decline, and the smelter was shut down. Despite these changes, East Helena continued to serve as a residential community for workers in the surrounding areas. Today, it retains its small-town charm, with a strong connection to its mining history.
