Team dives into deepest-known underwater cave in United States

A Texas A&M University at Galveston professor is part of a diving team that descended 462 feet in a West Texas cave, believed to be the deepest underwater cave in the United States.

Tom Iliffe, professor of marine biology and one of the world’s most experienced cave diving scientists, led a diving team on a seven-day trip to explore, map and investigate the depths of Phantom Springs Cave, located near Balmorhea in West Texas. Team members went as deep as 462 feet and recorded the dive on cameras, but still did not find the end of the cave.

“There’s really no telling how deep it is or how far the cave goes,” Iliffe says of the Jan. 8 cave dive.
