A 250-foot long, 10-foot wide lake rediscovered by Rene Rogers on January 23, 1999.  After finding this lake the exploration team consisting of Rene Rogers, Marc Ohms, and Paul Burger discovered a single set of foot prints on the far side of the lake. It has been speculated that these foot prints were from Alvin McDonald. Alvin reported discovering a river in the cave, which many people had discounted until Phantom Lake was found.
