In the area are a couple of historic sites. First we checked out Pictograph Cave. In 1937, archeologists retrieved 30,000 artifacts from the cave floor.
But the name comes from the pictures found on the cave wall, the oldest of which is over 2000 years old. Humm, let's see . . .
Well, I do see some red marks and if I zoom in and increase the contrast, there is something there.
We also stopped at Four Dances Recreation Area and hiked a short distance to an overlook of the Yellowstone River.
About 28 miles downstream is Pompey's Pillar. When the Lewis and Clark Expedition returned east, they split up to explore more waterways. William Clark's group took the Yellowstone River past this sandstone butte and named it for Sacagawea's son whom he had nicknamed Pomp.
On July 25, 1806, Captain Clark carved his name on the butte and due to preservation by the subsequent land owner, his name is still visible today.
Others have followed his example.
The visitor center is surprisingly elaborate with exhibits and a movie, but my favorite thing was a simple binder. Seventh graders had been asked what they thought the Pillar would look like in 100 years. There were a wide range of answers from a pile of rubble to something about space ships, but this was my favorite answer.
