History

Named for the many large boulders in the vicinity, the town of Boulder Valley was established in the early 1860s as a stagecoach station on the route between Fort Benton and Virginia City. It later became a trading center for nearby agricultural areas and the Elkhorn, Comet, and Baltimore mining districts. The Great Northern Railway branch line from Helena to Butte reached Boulder in 1888. State schools for the deaf, blind, and developmentally disabled were established in the city in 1892. In 1897, the town's name was shortened to Boulder.

Geography and geology

Boulder lies at an elevation of above sea level along Interstate 15 at its intersection with Montana Highway 69, approximately north of Butte, and south of Helena. The town is on the north bank of the Boulder River, a tributary of the Jefferson River. According to the United States Census Bureau, the city has a total area of , all land.

In the late Cretaceous Period (roughly 81 to 74 million years ago), molten rock (magma) rose to the Earth's surface in and near what later became Jefferson County and eventually formed an intrusive body of granitic rock up to thick and in diameter. This body, known as the Boulder Batholith, extends from Helena to Butte, and is the host rock for the many valuable ores mined in the region. As the granite cooled, it cracked, and hot solutions filled the cracks and formed mineral veins bearing gold and other metals. Millions of years later, weathering allowed gold in the veins to wash down to the gravels in the Boulder River valley. The Boulder mining district was essentially limited to placer mining of those gravels, because the source lodes were in other mining districts in the mountains.
