The Great Blue Hole is a giant submarine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km (43 mi) from the mainland and Belize City. The hole is circular in shape, over 300 m (984 ft) across and 108 m (354 ft) deep.

Analysis of stalactites found in the Great Blue Hole shows that formation took place 15,000 years ago.

Its almost perfect circular shape made it very popular among tourists who often visit this place, being the most attractive for scuba divers who are exploring its depths. Divers are also attracted with plenty of rare animal species and forms of life which can be found only in this place.

Located in northern California, the Monticello Dam is the largest morning glory spillway all over the world. This funnel-shaped outlet, allows water to bypass the dam when it reaches capacity, as it swallows a rate of 48,400 cubic feet per second (1370 m³/s). The distance from the funnel to the exit point – which is situated in the south side of the canyon – is about 700 feet. This type of spillway is basically a giant cement funnel. The hole’s largest diameter is 72 feet and narrows to about 28 feet. For obvious reasons, swimming near the glory hole is prohibited
