Bourbeuse Eagle Site (23FR152)

A pictograph site under a shallow overhang along the Bourbeuse River was discovered by R. Bruce McMillan during 1963. The site is situated on private property and is not open to the public. I first visited the site in 2014 with Neathery Fuller and revisited the site in 2020 with a team that included Eric Fuller, Thomas Mercer, Mark Leach and Alan Westfall.
