Using N6LF's formulas I get skin depths around 5-10 meters at 2MHz (0.005 S/m, epsilonr = 3-10)

You might get 60 feet (20 meters) if the soil is particularly non-conductive (rock). Dropping the conductivity to 0.5 mS/m gives you skin depths of 22-34 m at 2MHz

Rock and sand are quite prevelant throughout the west, and pretty much what we have in the mountains. :)
