Located at the base of the foothills of the Guadalupe Mountains, the Black River Recreation Area is an oasis in the desert. The Black River is spring fed through the gypsum karst system, giving it a unique color. Then it turns clear further downstream. Photo by @BLMNewMexico https://t.co/mFVX4lKgNp — PolitiTweet.org
