Geologists: what geology classes that you took are the most useful in your job?

Also, which classes do you use the least?

I think all geology classes are important, but the most important ones are:
- PHYSICAL GEOLOGY
- STRUCTURAL GEOLOGY
- MINERALOGY
- PETROLOGY
- SEDIMENTOLOGY & STRATIGRAPHY
- PALEONTOLOGY
- GEOPHYSICS
- FIELD GEOLOGY
Good luck!

Know of any universities that offer geology classes through distance learning?

I am not looking for a degree program, but rather individual classes, especially graduate level classes.

If you don't want it to count toward a degree.........

Anything to do with environmental abatement - this is one of the major issues of the 21st Century.
