DENVER (AP) — Authorities braced for the possibility of another landslide in a remote part of western Colorado as they surveyed a massive debris field Tuesday amid dangerously unstable conditions that led them to call off the search for three ranchers missing there.

Mesa County Sheriff Stan Hilkey said the search eventually could resume for Clancy Nichols, 51, who also worked as a county road and bridge employee; his son Danny Nichols, 24; and Wes Hawkins, 46.
