Teaching Notes and Tips
Since soil maps are available for much of the United States, it would be very easy to develop something for any given area/region. I have especially found it beneficial to incorporate activities where students do mapping, cross-sections, and timelines/reconstructions. To get started, I would recommend using a paper copy of the soil survey and consult the "General Soil Map", which is usually located in the middle of the book. This map is constructed at a scale of 1:250,000 and can be used to acquaint yourself with the basic soil geomorphology of the county.
Accuracy and completeness of map and/or cross-section
