Biological Scientist: ‘I Saw a Giant Beaver’

Minn. — A couple claim they encountered a giant beaver in northern Minnesota.


P. Pieper says he and his wife were in the wilderness of the region between the United States and Canada when they spotted the animal in 2007.

“We did not tell anyone because we did not think we would be believed,” Pieper told Cryptozoology News.

The man, who claims to be a UC Berkeley graduate, said he has a degree in biological science and that he is “very familiar” with North American mammals.

The creature, he explains, was approximately 5 to six feet long “not including the tail”.

“I estimate it might have weighed about 200 pounds.”

The rare report comes 31 years later after a man allegedly encountered a similar creature in an undisclosed location in the state of Maine. He said the animal was about 14 feet long and believes it weighed over 300 pounds.

It is believed that giant beavers, also known as Castoroides, went extinct about 10,000 years ago.

Arizona author and Bigfoot researcher Mitchell Waite last year said he and his team had seen a “giant rabbit” but were not able to capture it on video due to an “unexpected camera malfunction” they believe could be linked to the additional “strange activity” linked to the area.

    This should be extra easy to verify since beavers stay in their ponds. Since it is not verified I call BS.

    I have recently been studying local beavers and habitat, and have seen several river lodges about 9 feet tall, 15 feet wide, and up to 40 feet long.

    Then, after noting the shape, the linear design, and the level surface of the top,
    I recognized, in other places, HUGE structures at creekside, long abandoned, with the same characteristics.
    But these are about 50 feet high, 100 feet widee, and 200 feet long, also absolutely level on top.
    Both are in the southern Lake Michigan area, and the largest is about 5 miles south of the south most point of Lake Michigan.
    The creek now turn permanently to go around this structure.
    The soil here is clay, no rock, and no reason for such a structure to exist in the middle of this wide but shallow river valley where all the surrounding area is level flat. I am still looking for some kind of paleo-archeologist to discuss these.

      50 Feet high and 100 feet wide??? What on earth could make structures of this size??? Let me ask you: When you see one of these Giant Beavers in modern day like some have claimed to have seen, do they look really old and ancient or not??? I would think something this old and supposedly extinct would look exactly like such???
