Continue north from South Well for 3.3 miles to cattle guard. Turn left just before cattle guard and travel for 1 mile. Mass of particles collected by BSNE sampler. The BSNE sampler pointed into the wind and caught airborne particles through its 2 square centimeter area mouth. BSNE's have fins mounted on each collector to keep them pointed into the wind at all times.
Dust collection is done weekly.
There are 2 stands of 3 collectors each, installed near each of 3 instrumented towers on the Scrape Site. These are referred to as the West, Middle, and East towers and are used to reference the location for the BSNE collectors. The three towers are set on the direction that is that of the dominant wind eroding wind. The E or East tower is quit close to the deposition area East of the scraped site. The towers were set up to measure sand fluxes on a downwind line.
