BANDELIER NATIONAL MONUMENT, N.M. (AP) — Officials at Bandelier National Monument in northern New Mexico are planning to replace the wooden ladders that visitors use to reach some of caves and alcoves in the surrounding cliffs.

Monument staffers say maintenance and preservation crews will lay out and fit all the parts that make up the ladders and then do the actual assembly where each ladder will be used.

The long logs will be transported as far as possible by all-terrain vehicles on the trails and then hoisted up on the workers' shoulders and carried the rest of the way.

Rehabilitation of the roof on the kiva inside the Alcove House is also scheduled to begin in September along with trail work along the switchbacks that connect the monument's campground to the archaeological sites in Frijoles Canyon.
