Description :
A two-dimensional finite element stress model was applied to the analysis of six selected rock columns formed in welded, horizontally jointed tuff in the Chiricahua Mountains, Arizona. The modelling revealed that failure because of slip along inclined joints penetrating the rock was much more likely. The uniformity of column heights suggests that either rare, high velocity winds or prehistoric seismicity cropped the previous generation of columns to seismic shaking.
