Hiker disappears near New Mexico's Bandelier National Monument

Officials at Bandelier National Monument say a search is under way for a missing hiker who was in northern New Mexico to look for the buried treasure of a Santa Fe antiquities dealer.

Members of the New Mexico Search and Rescue team and the Los Alamos Police Department say dispatchers received a call Friday from a man in Texas who reported that his girlfriend was missing.

The woman arrived at the monument on Thursday to hike to the Upper Falls. She called her boyfriend to let him know she would return the next day. She hasn't been heard from since.

Searchers believe she headed toward the Rio Grande. The trail from the Upper Falls to the river is rough terrain, having been washed out by a flash flood in 2011.
