Finn Rock was once a logging community and is named after an unusual rock formation on Route 126 near the mouth of Finn Creek.[2][3] Although the rock resembles a shark's fin, the rock was named for Benjamin Franklin Finn, an early settler of the area.[3][4] Ben Finn was known as "the biggest liar on the McKenzie River", and claimed to be the inspiration for Mark Twain's Huckleberry Finn.[4][5] Finn Rock post office operated from 1947 until 1961.[3] The 1929 general store building that also served as the post office is now a restaurant.[2]
Finn Rock Rest Area, formerly known as Howard Morton State Park, is located near Finn Rock. McKenzie High School is located in Finn Rock.
