Butte to Scottsbluff Road Trip: Hidden Gems on I-90 & US-26

This 710-mile trek from Butte, MT to Scottsbluff, NE follows the old Oregon Trail alignment for much of its length, crossing the Continental Divide twice and passing within sight of the largest open-pit copper mine in the Americas—the Berkeley Pit. The drive takes roughly 11 hours without stops, but that would be a missed opportunity.

• Key highways: I-90 east from Butte to Sheridan, WY; then US-14 east to US-16/US-20 through Greybull; connect to US-26 south and east through Ogallala to Scottsbluff.
• Unique quirk: Between Casper and Scottsbluff, you'll cross the Oregon Trail Ruts at Guernsey, where wagon wheels carved grooves still visible in the sandstone.

The region's economy pivots on energy extraction—coal, uranium, and oil—, creating a landscape of open ranges punctuated by mining infrastructure. how to find the best stops and hidden gems between cities is relevant here because many worthwhile detours are unmarked.

The landscape transitions from the forested Rocky Mountains near Butte to the shortgrass prairie of eastern Wyoming and Nebraska. The Bighorn Mountains dominate the skyline east of Sheridan, with US-14 crossing the Cloud Peak Skyway (closure risk in winter).

• Geological wonders: Devil's Tower National Monument (WY) is a 45-min detour north of I-90; Scotts Bluff National Monument (NE) offers a stunning view of the North Platte River valley.
• Flora and fauna: Pronghorn antelope herds are common on US-26; prairie dogs and sage grouse near Guernsey. In spring, wildflower blooms in the Sweetwater Valley.

Local commerce reflects the energy and agricultural base.
