NABSQNO 13S-386810-3961090. This unnamed irregular natural arch has eroded through a tent rock of volcanic tuff. It is located along highway 4 southwest of White Rock, Los Alamos County, New Mexico. Although small, it is quite photogenic and has graced many brochures advertising the scenic qualities of the area.
