On February 17, 2012, ten contributing properties were listed on the National Register of Historic Places as part of the multiple property documentation form for El Camino Real de Tierra Adentro, the international historic trail linking Mexico City with northern New Mexico. Nearly 20 miles of the best-preserved ruts and swales marking the ancient Camino Real de Tierra Adentro had previously been added to the New Mexico State Register of Cultural Properties on December 10, 2010. The nominations were part of a package of 11 individual trail segments and an historic context for the trail.
New Mexico BLM administers all or part of eight of the nominated segments, including stretches of the 400-year old wagon road that crosses the Jornada del Muerto, the dreaded "Journey of the Dead Man," in southern New Mexico. Also included in the nomination are segments of trail at the mouth of the Santa Fe River, below La Bajada, and trail remnants on the Caja del Rio, above La Cieneguilla near Santa Fe. Linda Rundell, previous BLM state director, gave testimony before the New Mexico Cultural Properties Review Committee in favor of the nominations. John Roney, retired BLM Rio Puerco Field Office archaeologist, and his colleagues Mike Marshall and Tom Merlan, prepared the nomination package with support from BLM, the New Mexico Historic Preservation Division, and the National Park Service.
