Added a geotechnical talk

I added a geotechnical talk presented in January 2018 in Edmonton to APEGA (Association of Professional Engineers and Geoscientists of Alberta) entitled:

Civil engineering considerations within the Great Plains Polygonal Fault System

These contorted beds are thought to be caused by ‘glacial ice push’. However, examination of wellbore logs shows that the contorted beds exist underground for about 200 m. Therefore, I interpret these beds simply as exposed contorted beds from within the Great Plains PFS at outcrop. If so, this phenomenon should be considered (where applicable) by geotechnical engineers.
