Modern day Sasquatch is a very interesting topic. The first sight of the modern era was in 1811. A man in Jasper, Alberta, Canada had seen a large hairy man-like creature. The first reported Bigfoot attack came from the state of Washington in 1924. Sightings then died down until the 1950's which saw the first casts of feet as well as the coining of the phrase Bigfoot. Since then there have been hunters, organizations, science, and literature devoted to the topic of the existence of the creature.
