Homestake Pass, Montana: Traversing the Rocky Mountains on Interstate 90

Homestake Pass is a high mountain pass at an elevation of 1.954m (6,410ft) above the sea level, located on the boundary of Jefferson and Silver Bow counties, in the US state of Montana.

Is the Journey to Homestake Pass Fully Paved?

Situated amidst the Rocky Mountains and enveloped by the Beaverhead-Deerlodge National Forest, the road leading up to the summit is completely paved. It is called Interstate 90. Remarkably, Homestake Pass stands as the highest point on this expansive 4,861km (3,020 miles) highway. When Interstate 90 was established, Montana strategically utilized Homestake Pass to traverse the Continental Divide, offering a more convenient route than Pipestone Pass.

Homestake Pass: How Long and How Accessible?

Perched atop the Continental Divide, Homestake Pass stretches 39.91km (24.8 miles) from west to east, connecting Butte, the county seat of Silver Bow County, to the town of Whitehall in Jefferson County. Although the pass is usually open year-round, it's not uncommon to encounter brief closures during winter months due to adverse weather conditions.
