Exit Wonder World Cave by our “Stratavator” from the bottom of the cave. The shaft was created for exiting the cave and for viewing the many geological strata formations. Travel 190 feet upward into the Observation Museum in the Sky to see spectacular views of the dramatic shifting during the earthquake and the formation of the Balcones Fault Line Cave. Look over the escarpment’s breaking-off points that reveal the location of the fault line below. See the Hill Country’s uplift and the Gulf Coastal Plains dividing points that are the major distinguishing geological landmarks of Texas.
