An artist's cross-section of Lake Vostok, the largest known subglacial lake in Antarctica. Liquid water is thought to take thousands of years to pass through the lake, which is the size of North America's Lake Ontario.

I spent a few days in Banff National Park in Alberta, Canada, in September 2009 - WOW- what a place! Incredible scenery in all directions, great short and long hikes, surprisingly few people and excellent weather. This is a must see if you have a chance.

A Watery Lake Is Detected on Mars, Raising the Potential for Alien Life - The discovery suggests that watery conditions beneath the icy southern polar cap may have provided one of the critical building blocks for life on the red planet.
A view of the southern polar plain of Mars, with the Mars Express’s color-coded findings superimposed at the site where they were detected. The 12-mile-wide lake is believed to be about a mile deep.

An artist's representation of the Antarctic aquatic system scientists believe is buried beneath the Antarctic ice sheet.
First view of the bottom of Antarctic subglacial Lake Whillans, captured by the high-resolution imaging system aboard the Micro-Submersible Lake Exploration Device. The imagery and other data from the mini-sub were used to survey the lake floor and help the WISSARD team verify that the rest of their instruments could be safely deployed into the lake.

This Cassini false-color mosaic shows all synthetic-aperture radar images to date of Titan's north polar region. Approximately 60 percent of Titan's north polar region, above 60 degrees north latitude, is now mapped with radar. About 14 percent of the mapped region is covered by what is interpreted as liquid hydrocarbon lakes.
Features thought to be liquid are shown in blue and black, and the areas likely to be solid surface are tinted brown. The terrain in the upper left of this mosaic is imaged at lower resolution than the remainder of the image
Most of the many lakes and seas seen so far are contained in this image, including the largest known body of liquid on Titan. These seas are most likely filled with liquid ethane, methane and dissolved nitrogen.
Many bays, islands and presumed tributary networks are associated with the seas. The large feature in the upper right center of this image is at least 100,000 square kilometers (40,000 square miles) in area, greater in extent than Lake Superior (82,000 square kilometers or 32,000 square miles), one of Earth's largest lakes. This Titan feature covers a greater fraction of the surface, at least 0.12 percent, than the Black Sea, Earth's largest terrestrial inland sea, at 0.085 percent. Larger seas may exist, as it is probable that some of these bodies are connected, either in areas unmapped by radar or under the surface (see PIA08365).
Of the 400 observed lakes and seas, 70 percent of their area is taken up by large "seas" greater than 26,000 square kilometers (10,000 square miles).
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The radar instrument was built by JPL and the Italian Space Agency, working with team members from the United States and several European countries.

The original NASA image has been modified by rotating 90 degrees clockwise, cropping and reduction in size (the linear pixel density was reduced 50%).Some of the features in this image have been annotated in Wikimedia Commons.

Crater Lake is a caldera lake in the south of U.S. state of Oregon. It is the main feature of Crater Lake National Park and famous for its deep blue color and water clarity. With a maximum depth of almost 1950 feet (594 m) the lake partly fills a nearly 4,000 feet (1,220 m) deep caldera that was formed around 2000 (± 150) BC by the collapse of the volcano Mount Mazama.

This is a view from orbit of the Caspian Sea as imaged by the MODIS sensor on the Terra satellite. Caption: The original caption from NASA: ::"The northern part of the Caspian Sea is plagued by a process called eutrophication, in which agricultural run-off rich in fertilizers stimulates rampant growth of algae in the water. The death and decay of these algae robs the water of oxygen, with obvious negative consequences for aquatic life. This image of the Caspian Sea shows swirls of green and blue near the mouth of the Volga River (top center), which indicate the presence of algae. The bright blue color of the northeastern part of the sea may be due to a mixture of plant life and sediment, for this is where the sea is most shallow. This image is from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite on June 11, 2003.
