Comment:
Survey squares are shown in Figure 4 of the article. An average of 30 measurements were performed in each square to determine active-layer depth and shear strength. The measurements were performed within three days at the beginning of August 2006. The shear strength values were originally given in N/m**2 and were converted to kPa by dividing by 1000.
