Six Flags Over Mid-America Injun Joe's Cave Dark Ride

Today's flea market was very cold and not well attended. However one vendor who usually has some photos and other paper ephemera was there. In his boxes was this little group of four pictures from an unusual dark ride. With the photographs was a picture of the St. Louis arch. After a little Internet digging, I believe the images are from a dark ride located at Six Flags Over Mid America with the name Mississippi Adventure. Actually the snapshots are from Injun Joe's Cave. The ride was created by Arrow Development. This Six Flags park opened in 1971 and this was one of the rides at the park. The ride closed at the end of 1979 and rethemed to a time tunnel. The park is now named Six Flags St. Louis and features many roller coasters and other rides.
