A seasonal drop, Copper Adit Falls drains the old Copper Falls mine through a young forest and over a sudden drop onto the a wide expanse of stamp sands left from an old mill. The water bubbles up from the ground in a weird, spring-like fashion, before flooding through the forest along a young path. There is some remains of the old operation nearby for curious visitors.
Take Pine Street west out of Eagle Harbor, heading past the Pine Grove Cemetery and Eliza Lake on the way. Continue down the road as far as possible, parking and walking if the way gets too rough. After 1.9 miles the road turns sharply up the hill. Stop here and head down to the stamp sands, either by following the overflow downstream to the falls or just going down to the sands and walking west to the water.
