Navajo Sandstone Soft Sediment Deformation
38o 17.059' N
111o 09.854' W
This is another example of soft sediment deformation in the Navajo sandstone called a pop up/flower structure (Morris et al. 2003). This structure may have been caused by overpressurized pore pressures and strong ground motion (e.g., possible Jurassic seismic activity).
