These soils• <br />were not found to be dispersive, as defined ltv these tests. Some <br />of the native soils sampled .in this exploration progs•art~ were <br />found to be of relatively low density and tend to develop "l,ip- <br />ing" s~.ructures which are common for these soils in this nal.ive <br />grid environment. <br />i <br />
