A group from Transylvania College, now Transylvania University, including Dr. Willard Rouse Jillson, head of the college’s Geology Department, Bob Jones and Oscar Hinton, explored Crystal Cave in Pulaski County in October 1950. The cave would soon be under water as Lake Cumberland was created by impounding the Cumberland River with the Wolf Creek Dam. This photo ran with a story about the creation of Lake Cumberland and the flooding of the Cumberland River valley. The story and photo were published in the Lexington Leader on Oct. 31, 1950.
