For over three decades, the Sweetwater County Historical Society hosted summertime treks to historic sites around the county, often following emigrant trails, stagecoach roads and other historic routes. From the mid 1960s to the late 1980s, Henry F. Chadey, first director of the Sweetwater County Historical Museum, led many of these treks. Henry carefully researched, planned and coordinated these events, sometimes attended by as many as 300 participants.One of the more popular trek destinations was to Browns Park, a historic outlaw hideout on the Green River near the Wyoming-Colorado-Utah border. Frequented by infamous outlaws such as Butch Cassidy and the Sundance Kid, the park was a remote valley bordering three states, making it easier to escape the law. Of all Henry's treks, his Browns Park treks were probably the most popular and best documented.This book based on the Browns Park Flaming Gorge Trek: July 31, 1982 booklet published by the Sweetwater County Historical Society. Although it has been updated as much as possible-without losing the tenor of Henry's writing-it is not intended to be a definitive guidebook, but rather a commemoration to its author, the late Henry F. Chadey.
