• Road conditions: I-90 is well-maintained; US-85 has some two-lane sections with moderate traffic. Winter (Nov–Mar) may require snow tires.

Tolls: None along the route. Speed limits: 70–80 mph on interstates, 55–65 mph on US highways.

Recommended fuel strategy: Gas prices are lower in Wyoming than Montana, so fill up before crossing. Also, the stretch from Buffalo to Billings has limited services—plan accordingly.

Wildlife hazards: Deer and antelope frequent dawn/dusk hours, especially in the Powder River Basin. Use high beams when possible and watch for reflection.

• Frequent rest zones: I-90 rest areas near Crow Agency, MT (mile marker 72) and Livingston, MT (mm 334).
• Cell coverage: Spotty in northern Wyoming and central Montana; download offline maps.
• Weather apps: Use NOAA weather radio for sudden thunderstorms in summer.

Family-friendly stops: Devil's Tower (kids love the climbing rocks), Little Bighorn Battlefield (interactive exhibits), and the Yellowstone River picnic area near Billings.

Pet-friendly framework: Most motels along I-90 accept pets (La Quinta, Motel 6). Rest stops have pet areas; keep dogs on leash due to wildlife.

Fatigue management: Plan to stop every 2 hours. Park at scenic overlooks like the Tongue River Divide (elevation 6,000 ft) to stretch. Coffee at the Hitching Post in Sundance, WY is reliably strong.

Hidden off-route spots: Take WY-24 south of Devil's Tower to see the 'Sundance Kid's hideout' cave. Near Buffalo, WY, drive Old US-14 to the ghost town of Mayoworth.

The drive begins in the Black Hills, a Paleoproterozoic mountain range with granite spires and ponderosa pines. As you descend onto the Great Plains near Newcastle, WY, the terrain flattens into rolling grasslands punctuated by buttes and draws.

Near the Wyoming/South Dakota line, you'll cross the Belle Fourche River valley, a hotspot for fossil hunting—the area is part of the Hell Creek Formation, yielding Triceratops and Tyrannosaurus rex specimens.

Sheridan, WY—a historic railroad town—offers the King's Saddlery museum, showcasing Western equestrian gear. The nearby Bighorn National Forest provides hiking and scenic byways.

Moving into Montana, the landscape shifts again near Big Timber, where the Crazy Mountains jut dramatically from the plains. The Shields River valley is prime ranchland, and you can buy local beef jerky at roadside stands.

In Butte, the Berkeley Pit, a former open-pit copper mine, now a Superfund site, stands as a surreal testament to mining history. Walking tours detail the town's boom-and-bust cycles.

Finally, the Bitterroot Valley greets you with apple orchards and the Bitterroot River, a blue-ribbon trout stream. Local wineries, like the Ten Spoon Vineyard near Missoula, offer tastings.

For unique souvenirs: Deadwood's gold-panning kits, Sheridan's leather goods, Butte's copper jewelry, and Lolo's huckleberry preserves.
