EAST TANK BUTTE. East Tank Butte is in Petrified Forest NP, located in an area added to the park within the past few years, and not yet open to the public. It is a great site with hundreds of images. As a volunteer Photographer for the park, I recently photographed and mapped the site for the Chief Archeologist. Click on the first thumbnail to see larger image.
