Specialty drilling contractor Crux Subsurface recently completed geotechnical drilling for Kleinfelder at the site of a large landslide near Page, Arizona. Crux completed 17 holes to depths up to 250 feet using a combination of track-mounted and helicopter-moved drill rigs. Optical/acoustical downhole imaging was provided in three borings, and inclinometers were installed in seven borings. ADOT produced the following video showing parts of the geotechnical investigation.
