Customs and Border Protection just announced that the next round of detonations within the Huachuca Mountains will occur on Thursday, November 20 from 12 pm to 3 pm. The blast site is located 1,500 feet west of the southern terminus of the Arizona National Scenic Trail on lands managed by the Coronado National Forest. While the Arizona Trail is out of the immediate zone of impact and there is no threat from flying debris, visitors to Coronado National Memorial’s Montezuma Pass and the Arizona Trail (aka Yaqui Ridge Trail) are warned of impacts to scenery and natural quiet during these operations.
