Founded as a Northern Pacific Railroad town in 1882, Billings (Visitor Center 815 S. 27th St. +1 406 252 4016) has grown into a regional trade and agricultural center with sprawling industrial parks, commercial strips, and suburban neighborhoods. Start downtown, where a scattering of Victorian facades cheer up humdrum modern office buildings. One of them, a 1901 Romanesque library, houses the Western Heritage Center (2822 Montana Ave. +1 406 256 6809. Tues.-Sat.), where old photos, clothes, crafts, and gadgets depict the cultural history of the Yellowstone Valley. Another building, the old county jail, is now the Yellowstone Art Center (401 N. 27th St. +1 406 256 6804), which focuses on historical and contemporary Western art.You’ll find more turn-of-the-century buildings along Montana Avenue between 23rd and 26th Streets, but the grandest of Billings’ old Vics—the Moss Mansion (914 Division St. +1 406 256 5100. Adm. fee)—stands about 20 blocks to the west. Completed in 1903, the banker’s three-story red sandstone mansion gathers in a disparate mix of interior designs, as if the Mosses couldn’t decide which of the Old World potentates to emulate. There’s a Moorish entryway, a Tudor dining room, and a touch of Versailles in the parlor. Most furnishings are original.
For a good view of the city and a look at more frontier items, head northwest on Broadway to the Peter Yegen, Jr. Yellowstone County Museum (At Billings-Logan Intl. Airport 1950 Terminal Circle. +1 406 256 6811. Closed Sat.), set in an 1890s log cabin. For more great views, follow Montana 3 east to Black Otter Trail, which curves above town along the 400-foot-high [121.9-meter-high] rimrock, passing Boothill Cemetery.
East of Billings, Pictograph Cave State Park (6 miles [9.7 kilometers] S from Lockwood exit. +1 406 247 2940. Mid-Aprilmid-Oct.; Adm. fee) preserves a sandstone cave complex where generations of prehistoric hunters sharpened their stone spearpoints, cooked meals, made jewelry, and painted the walls with figures of animals and humans and with religious images. Artifacts date back 4,500 years, but archaeologists think the site could have been inhabited 10,000 years ago.
