Site details

Lake Pend Oreille is one of the deepest lakes in North America (about 1,150 feet) and holds more than 60 wrecks, mostly historic wooden boats. The signature dive is a set of sunken railroad gravel cars near Trestle Creek at the lake's north end, lost in 1904 when a trestle gave way. The first boxcar appears around 86 feet and the wreckage continues to about 110 to 112 feet, where divers can see the couplers between cars and swim into one boxcar. This is a deep, cold-water altitude dive accessed from the Trestle Creek boat launch near Hope.
