Give this a 5 if you're into Lewis & Clark. The visitor center has a small museum and a ten minute video. There is a staircase with more than 300 steps and walkways that take you up the rock to where William Clark carved his name in 1806. This is the only physical evidence that he was there. All other...

And in 1807 or there snouts Clarke carved his name on it as traders and Indians had done before It's the only physical evidence there was a Lewis and Clarke exposition. Clarke named the rock after...

Knowing that this rock contained the only physical evidence of Lewis and Clark's journey made it a must stop as I'm an extreme history buff. We were pleasantly surprised upon arriving, to note that there was a brand new visitor center on the premises. Everything on the site had been well planned and blended in well with the context and...

We stopped here on our way home from Yellowstone Park. It was a nice easy stop right off the Interstate with a gorgeous and well staffed visitor center. The walk up the stairs to the top of the rock was fun and there was a spectacular view! My kids ( 8 and 10) completed the Junior Ranger booklet here and... More

As huge Lewis and Clark fans, Pompey's pillar was a must visit. The only known physical evidence of the Voyage of Discovery was left by William Clark on this commanding stone. At the top the view towards the river was breathtaking, a paradise of green filled with birds. We will never forget our visit

William Clark's signature on this outcropping is the only visible evidence of Lewis & Clark's journey across the western U.S. in 1804-1806. Pompey's Pillar is definitely more than just visiting a rock, however. The walk up to the top of the rock has been recently redone with new steps and the views at the top give you a sense of...

Went during the off season so had to walk into the Pillar. The grounds are beautiful and the walk up to the top of the Pillar is not a problem. I recommend you move toward the river before climbing the Pillar as there is a stone that tell you about the signatures on the Pillar and who left them. You... More

The site is easy to get to, close to I-94. It overlooks the Yellowstone River, and you can get good photos from the top. The climb up the stairs to the top is not bad. The visitor center is very well done, focusing on the Lewis and Clark Expedition. The Clark signature on the rock is the only permanent mark... More

This is not a long stop but worth every minute there and up the stairs! We commented that with everything getting built up around it that the silo probably blocks the view they had. Oh no we were wrong.....what a view!!! Do take your mosquito spray though. Great little museum with lots of history and a film to watch.

We saw the signs during our drive, we decided to stop not really knowing what to expect. I thought it was a little Devils Tower. I found out that it was a lot more... Part of the Louis and Clark trail, this is where Clark signed his name in the sandstone in 1806. We took the guided tour that gave... More
