El Malpais National Monument

History

Designation

 

On December 31, 1987, Public Law 100-225 established El Malpais National Monument and El Malpais National Conservation Area in the State of New Mexico. The Act set aside for the benefit and enjoyment of future generations nationally significant features, such as the Grants Lava Flow, Las Ventanas Chacoan Archeological Site, Perpetual Ice Caves, and other prominent natural and cultural resources.The bill provides for 376,000 acres--262,000 as a national conservation area managed by the Bureau of Land Management and 114,000 acres as a national monument administered by the National Park Service. Legislation designates the Masau Trail, a vehicular tour route, linking El Malpais National 

Monument with other major sites of antiquity in New Mexico and Arizona. 


El Malpais National Monument's boundaries include lands south of Interstate 40 near Grants, the Sandstone Bluffs area on the east side of the malpais adjacent to Highway 117, and Highways 53 and 109 flank the western boundary. The National Conservation Area extends out and circumvents national monument lands on all sides except north. Much of the National Conservation Area has been designated Wilderness Area.
