Quitobaquito Springs in south-west Arizona has been called a biological wonderland with few equals. The springs are an oasis in the vast Sonoran desert along the US-Mexico border, held sacred by the O’odham people, who call it A’al Vaipia. … The spring, located within Organ Pipe Cactus national monument, provides one of the only reliable bodies of water for about 100 miles in any direction, making it vital for wildlife in the area and for humans who have lived here for millennia. But the spring is in trouble. In 2020, the Trump administration completed a 30ft-tall (9 meters) border wall in this remote area, during which time the spring flow dipped to an all-time low, and the pond partially dried up after its lining cracked. Now, plans are under way to build a second massive section of the wall, just 90-150 feet north of the existing one.
