The first documented report of Bigfoot by a settler in Washington can be traced back to Rocque Ducheney, a trader who worked for Hudson’s Bay Company. His daughter, Agnes Louise Ducheney-Eliot was quoted in ‘Told by the Pioneers‘ (page 111) that:
“Grandpa Ducheney firmly believed the story of the huge apes near St. Helens Mountain. He went there to hunt once and one of these apemen beckoned to him. He just turned and ran and ran until he reached home.”
There is no specific information concerning the date, but based on other events, the year range would have been 1850 to 1852.
