This image shows the crib of Michigan's DeTour Reef Lighthouse, which is an offshore lighthouse in Northern Lake Huron and is situated on a submerged rocky reef a mile off the southeastern tip of Michigan's Upper Peninsula. The lighthouse sits atop a 60' x 60' square by 22' tall box like wooden foundation built with 180,000 board feet of lumber. The crib was assembled on shore at DeTour Village, Michigan, and towed to the lighthouse's designated location. Once there it was sunk onto a 75' X 75" square leveled bed of crushed rock. The crib's interior compartments were then filled with rock and the outer ones with concrete. Additional concrete was poured around its base forming an apron, and rock riprap was placed on top and beyond the concrete apron to further protect the structure.
