Site details

A diver-created wreck park on the northeast side of Sentinel Island in Boulder Basin, where the local technical diving community has gathered roughly a dozen sunken boats found around Lake Mead. Several wrecks are linked by permanent high-visibility cave line starting near 140 ft and descending past 300 ft, including the Southern Cross (penetrable) and smaller speed and ski boats. The shallower wall above the wrecks makes a good recreational dive, while the wreck line itself is technical territory.
