Most of our standard mammal field guides confirm this with a drawing of a bear on its hind legs. I suggest that these field guides hold a great deal of authority and I for one, am not in the habit of disputing them. But when someone gets a good look at a sasquatch they know that they have seen something other than a bear on its hind legs. I think one of the larger contributions of my book is to provide field guide-type illustrations of a sasquatch and compare them with similar drawings of a black bear. In front view, note that a bear has tapered, sloping shoulders and short hind legs.
Ears are usually visible.
Ears are not usually seen. In profile a bear has a prominent snout whereas a sasquatch has a flat face.
