For many years John and Carol Adams of Rochester would drive by Tunnel Mill, enchanted by its beautiful setting. Finally, in 1982, they negotiated with owner Larry Maus to purchase the mill about five miles north of Spring Valley on Hwy. #1. Badly deteriorated, the mill has seen unbelievable rehabilitation. Maus had bought it from Stafford Hansen in 1972 with the intention of restoring it to its former glory: tuck-pointing the foundation, insulating the structure, and doing upgrades throughout. Maus sought to have it designated to the National Register of Historic Places (and it is indeed) as it was "one of a kind" and Maus loved its history. He hoped to make it livable, the biggest obstacle being able to finance the project, and he cautioned he might not be able to bear the cost.
