Lake Cardiel

iss071e582300 (Sept. 2, 2024) -- Lake Cardiel is pictured from the International Space Station as it orbited 268 miles above Argentina. The lake is highly favored by fisherman as its alkaline water creates a rich habitat for salmon and other species to live. Its color results from nearby glaciers grinding rock into "glacial flour." The sediment is picked up by meltwater streams that feed into the lake and are slow to sink to the bottom, making the water appear a bright turquoise.
