Dexter Lake is one of smaller lakes in Ferris Lake Wild Forest, known mostly for it's heart shape and how it's very centrally located in forest, in pretty remote country. There is one campsite on western shore on the Dry Lake Trail.

For a long time I've wanted to hike back to Ferris Lake but it's not the easiest hike ever as you have to either cross the East Canada Creek or Black Cat Creek, both of which are muddy and difficult to wade across -- I got up to my knees in mud trying to cross the north fork of the East Canada Creek behind Campsite 12. Ended up putting in my kayak under Powley Bridge, and paddling to Franks Pond Outlet, bushwhacking on the ridge around Franks Pond and then heading down the hill to Ferris Lake. It's less then a mile from Piseco-Powley Road but the terrian makes it challenging if not impossible to access Ferris Lake without a canoe or kayak to get across what seems like a relatively small creek.
