Castner Range is a site with ancient rock art, cultural deposits, and historic military locations. The land, which is a part of Fort Bliss, was a training site up until 1966 and needed to be remediated because of unexploded munitions. It is known for waves of yellow and orange poppies in the spring.”When you see it, it’s just breathtaking,” Biden said. “Once it is safe for public access following remediation of military munitions … Castner Range will become a natural classroom offering unique opportunities to experience, explore, and learn from nature in a unique setting that is close to a major urban center.”
