tarradiddle of cryptids like the bugbear , yeti , andLoch Ness monsterpersist over fourth dimension thanks to " sighting " , alleged witness report , and dubitable write up extend back through the history of all thing unexplainable . Few have quite the telecasting footage though as one event impute to " Colossal Claude " .

Colossal Claude issaid to roamthe waters around the Columbia river , in Oregon , USA , and has supposed sightings date back to the 1930s . He was first " spotted " by the crew of the Lightship Columbia in 1934 , who reported Colossal Claude to be a huge tool around 12 meter ( 40 metrical unit ) in duration . The ocean behemoth is sound out to resemble a long serpentine animal with a thick body and immorality - appear horse - similar head . The crew even watched Claude for some fourth dimension through binoculars before deciding against engage him for fear he would flood the boat .

Only a few years later , another report of Colossal Claude turn up in 1937 from the skipper of a sportfishing trawler call the Viv , who report a " long , haired tan - color animal , with the head of an overgrown horse , about 40 feet [ 12 meters ] long , with a 4 - foot [ 1.2 - meter ] waist . " Similarly , another reportfrom a halibut fishing boat , the Argo , described Claude having coarse gray fur , as the crew watched him tuck into some fish .

A few more patchy reports have been append over the years but most seem to slip aside , until two citizenry adjudicate to go kayaking on June 29 , 2017 .

However , they report meet strange house of cards rising up from the aerofoil of the lake , despite a lack of current or any alteration in atmospheric condition conditions .

dip their camera under the water reveals swirling debris and bubbles , then an eruption of what looks like dark brown mud and leaves come at the surface , which , according to the video , stank ! The snip below is from season three ofThe Proof Is Out There .

There is some suggestion that Colossal Claude could be come after the Salmon River population from the ocean into the lake to feast on them . However , as one of the nautical biologists points , out the Salmon River population has minify within the Columbia River so there are unlikely to be obscure large wight living in Yale Lake .

One more likely account is given in the video by geologist Bob Anderson . He suggests that the bubbles are just make by natural accelerator trapped at the bottom of the lake bed . This would also explain the awful smell that the kayaker complain about as atomic number 1 sulfide and methane gas are released .
