I'm by no means an expert in these things, but the first time I traveled to the east coast from my home in the western US, I was struck by how much darker the soil is there. Rich dark brown. Thousands or millions of years of lots more vegetation growing means lots more vegetation decomposing and adding more organic material to the soil.
In contrast, the dirt where I'm from (Tucson) is very pale in color, presumably because we've long been a desert, and don't have nearly as much plant matter adding to our soil. So using my own very limited experience as a guide, I would analyze the picture this way: The dirt in this picture is not quite the same color as what it would be in my area, but definitely a little bit lighter than what I would expect from some place like Virginia. So, not necessarily the dirt of a harsh desert like Tucson, but definitely the dirt of somewhere in the Western US.
