Don Juan Pond is a little, lower leg profound lake placed in the Mcmurdo Dry Valleys of Antarctica, settled in Wright Valley between the Asgard Mountain Range and the Olympus Mountain Range. With a saltiness level of in excess of 40%, it is the saltiest known waterway on earth. The lake is 18 times saltier than the sea, or twice as salty as the Dead Sea in Jordan. Despite the fact that its arranged in one of the coldest district in Antarctica, its salty to the point that it never stops even in temperatures as low as low as minus 40 degrees Celsius.
It's accepted that Don Juan Pond gets its salt from groundwater stream leaking down from the bases of the Olympus and Asgard Ranges, and dissolving minerals from the encompassing rocks. Be that as it may, late studies by a group of geologists from Brown University recommends that Don Juan Pond gets its salt from precipitation, not groundwater.

Analysts have discovered that when the humidity in the air spikes, surface salt close to the lake ingests that stickiness as a component of a procedure called deliquescence. Those water-laden salts then trickle down through the detached soil until they achieve the permafrost layer underneath. There they sit until the infrequent stream of snowmelt washes the salts down the channel and into the lake. The discoveries have high ramifications on the grounds that it recommends that waterways like this could structure on Mars.
The pictures of water tracks at Don Juan Pond look a considerable measure like peculiarities as of late imaged on Mars called repeating incline lineae, the scientists say. The gimmicks show up on Mars as dull streaks that appear to stream downslope on cliff faces. They frequently repeat in the same spots at the same times of year, henceforth their name. A few researchers accept these streaks demonstrate a streaming brackish water, the best proof yet that there may be streaming water on present day Mars.
Furthermore, chloride-bearing salts have been identified on Mars, which would be fit for the same kind deliquescence seen in Antarctica. Furthermore vitally, the methodologies at Don Juan Pond oblige no groundwater, which is not thought to exist as of now on Mars.
Researchers have since quite a while ago contended that Don Juan Pond is the best conceivable area in which to recreate conditions where life on Mars may exist, because of the great states of extreme frosty, aridity, hypersalinity and amazingly high ultraviolet radiation.
Wear Juan Pond is named after two helicopter pilots - Lt Don Roe and Lt John Hickey, who found the pond in 1961.
