I was more interested in actually doing
precise measurements, but considered it might improve my model accuracy. I
even thought of digging a hole to see how the soil varied. Doubt I would
have dug down 20 or 30 ft. Most of the ground here is clay, and then
probably bedrock, at this elevation of just over 4,000 ft ASL. Ansoft's
HFSS, or CST, could probably handle an accurate, stratified, ground model.

Rudy Severns, N6LF, has an interesting paper on making ground
measurements at:
