lake with telling depth or unequaled geologic feature that obscure their true scale are often , deceptively , pronounce as “ bottomless lakes ” . Despite lakes being found atstaggering elevationsand being able-bodied toproduce their own tsunamis , they still lack one feature : an actual bottomless astuteness .

While no lake can in truth claim to be bottomless , some seem imposingly close by either plunging to monumental depths or featuring characteristics that make the conjuring trick of being never - end .

The world’s deepest lakes

The deepest lake on Earth , Lake Baikal , reaches an extraordinary depth of 1,642 metre ( 5,387 feet ) . Located in Siberia , Russia , it contains about 20 pct of Earth ’s unfrozen freshwater , making it the large freshwater lake by mass .

As the world ’s oldest eff lake , having formed around25 millionyears ago , Baikal ’s remarkable deepness is partly due to the area’stectonic activity , as it lies at a diverging crustal plate bound . Nestled in the planet ’s deepest continental rift , Lake Baikal is feed by over 300 rivers and drain by just one , leaving its unreachable bottom more than a km below sea level .

Another lake that could easily be assume to be bottomless isLake Tanganyika , located in Africa , bound Zambia , Burundi , Tanzania , and the Democratic Republic of the Congo . At a depth of 1,436 meters ( 4,710 human foot ) , it ’s the populace ’s secondly - deepest lake – and , stretching 660 kilometers ( 410 Admiralty mile ) , it is also the longest fresh water lake . With its brackish waters , the lake sits at the crossroads of eastern and westerly African flowered regions , supporting a robust diversity of works and animal life .

Sinkholes and cenotes

Aside from lake that are just incredibly thick , some of the most convincing bodies of body of water to appear " bottomless " come in the descriptor of swallow hole orcenotes – which are take form when the top of a cave body structure break , exposing a large pee - fill cavity .

As cenotes work around sometimes vast cave organization , they can look like simple-minded lake from the surface , but with a deep base that extends to the cavernous space below . unwashed in the Yucatán Peninsula , cenotes were once used as sites for ritualistic offering whereby object , and sometimes mankind , were thrown into their apparent never - ending depths .

TheGreat Blue Holein the Caribbean Sea is a giant underwater swallow hole that plunges 124 metre ( 407 feet ) . Aerial views of the hole show a vast cavern surrounded by shallow ocean water , this enticing body structure and its clear-cut waters make it a popular site for divers .

In the United States , Bottomless Lakes State Parkin New Mexico is home to nine sinkholes , ranging from 5.5 to 27 meters ( 18 to 90 pes ) in depth . The lakes ’ murky waters may have fuel the myth of their " bottomless " nature . However , the park ’s namereportedlyoriginated from a mathematical group of vaqueros – Mexican cowpoke – who , in an attempt to measure the deepness of the lake , marry rope together and dropped them into the H2O . When the R-2 failed to strain the bottom , the lake were deemed “ bottomless ” .

While no lake is really bottomless , some come pretty near with their impressive profoundness or features that give the magic trick of endlessness . These lake preserve ancient ecosystem and provide worthful perceptivity into Earth ’s history , raise that , while we may never find a sincerely bottomless lake , what lies below can still be fascinating .
