Stabilization of a reactivated landslide near Wagon Mound on Interstate 25
Arlon D. Lovelace

Abstract:

Wagon Mound lies in north central New Mexico. The surrounding area is characterized by large volcanic buttes and lava flows that terminate in bluffs west of Interstate Highway 25 near a dry lake bed. Interstate 25 skirts the edge of a basalt-capped mesa whose perimeter is composed of landslide debris. One problem that arose during construction of the highway was a landslide condition which developed during excavation on the north end of the project. On February 4, 1970, during the final stages of excavation between stations 1 1306 and 1317, an ancient landslide was reactivated and movement and cracking were noted. On February 10, as the excavation continued, a small perched groundwater reservoir was breached and an estimated 10,000 gallons of water were released.
