In 1932, Missouri Caverns was opened as the first electrically lit cave in the Missouri Ozarks region. Though the entrance is now sealed, the ruins of the buildings over the entrance still exist not far from the current visitor parking area. Onondaga now had competition on two fronts from both Cathedral Cave and from the back portion of itself under the name Missouri Caverns. The court battles continued over the land disputes, and Onondaga suffered due to its more distant position from US 66 on State Road H, as compared to the closer Missouri Caverns.
