Montana is certainly known for its beauty, but there’s quite a bit of history here, too. You’ll find it in any of the local museums found throughout the state, but there’s also plenty to soak up just by simply hopping in the car to explore. Those who grew up in the state will recall learning about Lewis and Clark’s Expedition through the west resulting in the mapping of land, rivers, and mountains. While it’s important to mention that the expedition aided in the increase of people in the east moving west, negatively impacting the local indigenous populations, there are many parts of their story. And all of it is worth learning and understanding. As you explore the history, one interesting place to visit is this unique national monument in Montana, Pompeys Pillar National Monument in Yellowstone County.

Pompeys Pillar National Monument can be found off of Highway 312, near the Yellowstone River. From far away it might simply look like a rock, but get closer and you'll see there's more to it.

The sandstone outcrop features markings and petroglyphs that truly mark the history and passage of time. In a way, it exists as its own history book. One of the more recent pieces of history is the signature of Captain William Clark etched into the rock along with the date of July 25, 1806.

Pompeys Pillar National Monument offers an Interpretive Center to learn about the area. While this and the main gates are open only seasonally between May and September visitors can walk about 3/4 of a mile from the gate to explore year-round during daylight hours. To learn more about planning your visit be sure to check out the Bureau of Land Management website’s dedicated page.

Note that the restrooms, interpretive center, parking lot, and day-use sections are all fully accessible. Dogs are permitted but must be kept on a leash.

This is a great stop to make as part of a fun road trip. But, as always, don’t even think about heading out on a road adventure without packing the best snacks. Along with a visit to this national monument, there are lots of other fun facts you probably didn’t know about the state of Montana.
