View along the Santa Fe Fault

The margin of the Rio Grande Rift is structurally very complicated in this view to the North along the Santa Fe fault west of Los Lunas, NM. A monocline cored by the Laramide Comanche Fault is cut by the rift-bounding Santa Fe Fault. Fanning of Santa Fe Group sediments along the fault indicates that faulting continued as rift sediments accumulated.

This spot is described in more detail in the Day 2 Road Log of the guidebook for the 2016 NMGS Fall Field Conference to Belen Area.
