Standard procedure for finding out what animals live in an area is to place a bait station in a clear space, then stretch a barb wire fence around it.
As the animals crawl through the fencing some hairs will be caught in the wire, and an analysis will tell what type of animal it is.
In the last sixty years, no hairs considered to be “Sasquatch” or Bigfoot has ever been found.
