 Between the 1930s and the 1950s there was also an " Auto Tourist Camp " where large numbers of tourists tented or stayed in small cabins . A park historian states that in those years " the camp was intended to appeal to the many tourists who were traveling the country in their new automobiles " . At one time there were several grist mills located on Minnehaha Creek . The remains of a stone and earth dam of a mill , built in the lower glen in 1853 or 1854 , is still visible beside the creek .
