"Six months after a sinkhole opened up atop a golf course at Big Cedar Lodge’s Top of the Rock Ozarks Heritage Preserve, noted conservationist and Bass Pro Shops founder Johnny Morris is deep into a national treasure hunt that may well reveal a hidden natural wonder buried deep within the Ozarks.
In May 2015 a collapse occurred after heavy rainfalls throughout the Ozark region, resulting in the creation of a large sinkhole spanning 70 feet across and running 40 feet deep. The spectacle occurred directly adjacent to the meticulously landscaped Tom Watson-designed putting green and drew worldwide media attention to Big Cedar Lodge and Top of the Rock Golf Course, just south of Branson, Missouri.
After confirming the site’s stability geological engineers suggested filling the hole with large boulders and restoring the golf course to its original design. Morris, however, chose to explore in the hopes of finding a secret passageway and uncovering a massive cave system underneath the golf course and surrounding area."
