At the end of July of 2006, a massive monsoon rain storm pounded the Santa Catalina Mountains northeast of Tucson. The USGS reported approximately 240 new slope failures occurred as a result of the storm. At least two notable failures occurred along the Catalina Highway that goes from Tucson to the town of Winterhaven and Ski Valley at the top of Mt. Lemmon. NCS was tasked by Pima County to design fixes for two of these sites. Both were fixed using soil nailing techniques.
