The valley lies between Sapp Rocks and Forlidas Ridge and heads in the amphitheater between Nutt Bluff and Preslik Spur.

Ford (1979-2000) on the geochronology and petrology of the Dufek Intrusion of the northern Pensacola Mountains was critical for the understanding of the evolution of this major igneous complex.

Named by US-ACAN after Charles W. Forlidas, radioman, Ellsworth Station winter party, 1957.

A round frozen pond, 100 metres (330 ft) in diameter, lying in a morainal valley east of the north end of Forlidas Ridge.

The pond was discovered and briefly investigated in December 1957 by a US-IGY party from Ellsworth Station.

The name is in association with Forlidas Ridge and was suggested by Arthur B. Ford of USGS following geological work in the area, 1978-79.
