Info

Erosion: There has been post airport construction gully erosion on parts of the slope near where this profile was described, but not at the site of this profile. Moisture condition when described: The soil was moist throughout when described. Picture of profile described, taken by Matt Salos, Oct. 3, 2011, the same day the pit was opened with backhoe by Ed Wallis, SRAP Manager of Pit 2 at the airport for the Nov. 4, 2011 VAPSS/MAPSS tour. The light gray clayey soil materials were rock-like (Ed’s term was non-durable stone) and when broken up and tested with 30% hydrogen peroxide gave a violent heat-generating reaction, however, it took about 15 minutes for the reaction to “take off”, probably because of low surface area available for the reaction. Fracture surfaces in this rock-like material were decorated with iron oxide and jarosite concentrations. 20
