What are the job prospects for Geology majors?

I am applying into several colleges. I am torn between an engineering major and geology. What is the demand for Geology graduates? Where are the jobs? I assume the possibilities are everywhere in the world, but is there a geographic concentration?

Some useful comments are in the thread http://talk.collegeconfidential.com/science-majors/1367603-geology-major.html (even though it’s about 3 years old).

Obviously, the petroleum-related jobs are where the oil is.
