Angel Falls is a 90-foot (27 m) waterfall on Mountain Brook in Township D – northwest of Houghton – in the White Mountains of Franklin County, Maine. The "remarkably scenic"[2] Angel Falls is a set of plunging tiers totaling 90 feet (27 m) in height, and with surrounding cliffs of 115 feet (35 m) in height. Flowing out of a 25-foot-wide gap (7.6 m) in the cliff, it is thought by many to be the tallest waterfall in Maine, tied for height with Moxie Falls,[2] though this is not the case; as Katahdin Falls, also in Maine, is some 710 feet (220 m) taller.[1] Angel Falls is so named as, when the water flow is right, the falls appear as an angel.[3]
