In different areas of North America, people have found trees, big trees, that have been uprooted and shoved back down into the ground in an inverted position. Does bigfoot cause this, or is there some other explanation?
One photo on that site shows an upside down tree found on top of a ridge in Northern Colorado. It was located near an old burn area and the site says, “This is Sasquatch related activity mainly found in the West, Canada, and Alaska.” The upside down tree is estimated to be about 30 feet tall and looks as if it has been in that position for awhile. As noted on that site such a feat would require either machinery or a phenomenal amount of strength.
