Mount Desert Rock
About 20 miles southeast of Mount Desert Island, this is one of the most remote and lonely lights. Even mild storms scour the island, denuding it of anything not firmly secured, and frequently submerge it entirely. Yet each spring keepers transported soil from the mainland, tucking it into crevices on this otherwise barren rock in hopes of cultivating flowers and vegetables. For a few months in summer and early fall, the rock became a colorful garden in the middle of the sea. But late fall and winter storms always washed it all away. It's a challenge to see this lighthouse, even from a boat, but whale-watching cruises from Bar Harbor sometimes pass by.
Mount Desert Rock Lighthouse was built in 1830.
