Contest #432: Landslide dam at the confluence of Clearwater and Cathedral Creeks, Nahanni National Park, NWT Canada

Contest #432 is a lake found behind a landslide dam in Nahanni National Park in the Northwest Territories of Canada.

The lake was formed when a landslide occurred during the winter of 1996-97 forming a landslide dam at the confluence of the Cathedral and Clearwater Creeks, just north of Virginia Falls on the South Nahanni River. In July 1997, part of the dam collapsed on Clearwater Creek with the lake that had formed behind the dam resulting in a large volume of water surging into the South Nahanni River causing water levels to rise rapidly but briefly.

The landslide dam across Cathedral Creek remains in place at this time. It is not obvious that there is any work being done to mitigate the collapse of this dam, with nearly 20 years of water in Cathedral Creek now stockpiled behind the dam.

Contest #427 Bull Arm, Newfoundland, Canada – site for the construction of the Hebron Project drill platform

Bull Arm, Newfoundland, Canada is the construction site for the Hebron Project drill platform. This week’s image shows the Gravity Base Structure (GBS) still in its dry dock, before the dry dock was flooded and the platform floated out into Bull Arm for final preparations. The base structure will have the top side structure attached and eventually will be sunk to the bottom of the Atlantic Ocean.

The GBS is scheduled to be in place and pumping oil by 2018.

Contest #424 Verdenskortet, near Hobro, Denmark

A world in a lake in the world – Verdenskortet is Danish for “world map”. This incredible piece of work is found in Lake Klejtrup, southwest of Hobro, Denmark. Built between 1944 and 1969, the map was the handy work of Søren Paulson, a farmer living on family land with an adjacent lake. It’s about 300 feet by 150 feet in size, and 10 inches on the map corresponds to a scale of about 69 miles.
