Buffalo Bill dam is just West of Cody Wyoming. The dam is named after William “Buffalo Bill” Cody. He founded Cody Wyoming and also owned most of the land the reservoir now encompasses. The dam was built between 1905 and 1910 and at a height of 325 feet was the tallest dam built at the time. There is a visitor’s center on site and you can walk across the entire dam. There is a small guard rail of course but it allows you to get incredibly close to the edge and look 325 feet straight down to the canyon floor. See pictures of my toes on the edge below. Everything in Cody Wyoming seems to be named after Buffalo Bill. Cody is a great little town and has bull riding every night of the week.
