Portions of the North Kaibab trail, between Manzanita and Supai Tunnel, will be closed beginning at sunrise on Monday, December 18 and ending at sunset on Sunday, December 24. Closures will be in effect from 8 a.m. until 4 p.m. to allow for contractors to install seismic survey nodes in Roaring Springs Canyon.
Work crews will be installing survey nodes in highly technical terrain above the trail, which may result in inadvertent and unpredictable rock fall onto the North Kaibab Trail. These survey nodes are small, wireless sensors that will be able to detect and record seismic activity in the area.
