Bluffs near Rocheport on Katy Trail
From June 1 to June 8, 1904, the Lewis and Clark Expedition passed through the scenic bluff country that is now part of the Katy Trail manitou pictographState Park. The trail passes Roche Percee Natural Arch which was seen by Lewis and Clark on June 6. The expedition passed the Big Manitou Bluff the next day and Clark recorded the pictographs he saw painted on the bluff that the Katy Trail tunnel now passed through.
