Raymond John Pool, Popular Science Monthly (1912)
“ There are many people who still think that the Sand Hill region is a plantless waste of wandering dunes. This is far from fact, but nevertheless the vegetation of the region is sparse and there are also many instances of actively moving sands, although by far the greatest portion of the area is effectively protected from wind erosion by the presence of vegetation. Nowhere except in the moister habitats, as in the valleys, do the plants grow densely or close together. On the hills proper the light-colored sand always shows between the individual plants. ”
