In 1974, the US Army Corps of Engineers included Sasquatch as a species in the state of Washington. The Army Corps of Engineers devoted a complete page to Bigfoot in their 1974 Washington Environmental Atlas.
In the Atlas it describes Bigfoot as standing 8 to 12 feet tall, weighing up to 1000 pounds and having feet measuring up to 24 inches long.
Does Bigfoot exist? Well the Army seems to think so.
