Mongolia - October 7th, 2009

The lakes visible here in the Khyargas District of Mongolia’s Uvs Province are part of the same system interconnected lakes in the Great Lakes Depression.

The large, dark greenish blue lake at the top is Lake Khyargas, upon which the Khyargas Nuur National Park is based.  This protected area was established in 2000 and covers about 3,328 km². It also includes the smaller, lighter green, freshwater Lake Airag, just south of Lake Khyargas.

In the lower left quadrant is Lake Khar-Us. Its area value of 1,852 km² includes the island Agbash (or Ak-Bashi, White Head) with an area of 274 km², so the water surface area is 1,578 km² only. Here, the island appears to almost separate the bright green western side of the lake from the brown right side. Primary inflow is the Khovd Gol river, which creates a large fan-shaped river delta on the western shores.

Finally, in the lower right quadrant are Lakes Khar and Dörgön. The waters of Lake Khar, above, appear green, while those of Lake Dörgön, below, appear dark blue.

Great Lakes Depression, Mongolia - June 8th, 2009

Great Lakes Depression, Mongolia - June 8th, 2009

The greenish waters of several lakes in Mongolia’s Great Lakes Depression stand out against the surrounding dry, tan landscape.

The lake on the bottom left is Khar-Us Nuur, or “Black Water Lake” despite its green appearance here. Its area value  of 1,852 km² includes the island Agbash (or Ak-Bashi, White Head), with an area of 274 km², meaning the lake’s actual water surface area is only 1,578 km².

The lake’s primary inflow is from the Khovd Gol river, which creates a large river delta whose fanned shape is visible on the western shore.

It is the upper one in a system of the interconnected lakes: Khar-Us Nuur, Khar Nuur, Dörgön Nuur, Airag Nuur and Khyargas Nuur. Khar Nuur (above) and Dörgön Nuur (below) are located to the east of Khar-Us Nuur, while Khyargas Nuur (above) and Airag Nuur (below) are situated to the north.

The Great Lakes have completed thawing and are now entirely ice free, as the land around them becomes green with spring foliage.

The lakes appear dark blue and mostly free of sediments, with the exception of Lake Erie, which has some greenish swirls of sediments in its southern portion and around Long Point.

Long Point is a sand spit and wetlands area located on Lake Erie’s north shore in the province of Ontario, Canada. It is approximately 40-km long and is about a kilometre wide at its thickest point. Long Point Bay is on the north side of the spit, while most of the sediments flow off its southern side.

The Laurentian Great Lakes are a chain of freshwater lakes located in eastern North America, on the Canada – United States border. Consisting of Lakes Superior, Michigan, Huron, Erie, and Ontario (from left to right), they form the largest group of freshwater lakes on Earth.

The lakes are bound by the Canadian province of Ontario and the U.S. states of Minnesota, Wisconsin, Michigan, Illinois, New York, Indiana, Ohio, and Pennsylvania. Four of the five lakes form part of the Canada-United States border; the fifth, Lake Michigan, is contained entirely within the United States.

The Saint Lawrence River, which marks the same international border for a portion of its course, is the primary outlet of these interconnected lakes, and flows through Quebec and past the Gaspé Peninsula to the northern Atlantic Ocean.

These images were captured in early spring, after warmer temperatures had thawed much of the ice that frequently covers the lakes in winter. However, as can be observed in the close-ups, a patch of ice is still visible at the northernmost tip of Lake Erie, and in the marshy areas along the northern shores of Lake Huron.

Lake Erie has a substantial amont of greenish-yellow sediments clouding its waters from shore to shore. Lake Huron and Lake Michigan also have some sediments, though these are limited to their southern coastlines.

The Great Lakes, on the border of Canada and the United States of America, are partially surrounded by snow.

Cold temperatures have caused parts of them to ice over, as seen in the close-ups of Lakes Erie, Huron and Michigan.

To the right, clouds from a snowstorm over the East Coast are visible.

The storm hit the southeastern states on Sunday, causing many problems such as power outages and automobile accidents, reported NBC News, as the region is not accustomed to dealing with such extreme weather.

The storm then progressed to the northeastern states on Monday, causing more car crashes and between 8 and 12 inches of snow in New England.
