Advanced General Geology is an introductory class in geology designed for students who have some science background. A laboratory run in conjunction with the lecture is designed to introduce students to rocks and rock forming minerals. There are at least two required day-long field trips. The required text is The Inaccessible Earth by Brown and Mussett (this text is out of print, so copies can be obtained from the DEES office in Schermerhorn).  There will also be a large number of supplemental readings and handouts given at the beginning of lectures. A copy of Earth by Press and Siever is on reserve in the library as a general reference.
