Ancient Lake Falls pours off the basalt benches into the Ancient Lakes basin in Potholes Coulee. WTA describes a waterfall dropping 160 feet into the basin below Judith Pool; this listing is probably that waterfall, but that is not confirmed. From the south end of the parking area on Babcock Bench, follow the old two-track 0.6 mile to a junction, take the left fork and follow it up the coulee 1.5 miles to the lakes. Several old two-tracks and game trails lead up the coulee. The falls are at the east end of the basin; around the lakes WTA says you can follow the numerous trails or walk cross-country.
