Reddit mentions of Geoscience Handbook: AGI Data Sheets, 4th (revised) Edition

I did field camp at sac state. It was a lot of fun, I highly recommend it. But it can be a lot of work and stressful at times. The entire geology program at sac state is very field heavy so by the time you get to Sr. Field the professors expect you to work independently. So if you have experience mapping, identifying different rocks, and interpreting their structural relationships to each other you have nothing to worry about. If I was you I’d make sure day one to know the geologic timescale and IUGS igneous rock classification by heart. That stuff will come in handy. Also I recommend getting some kind of field reference book. This is the one I used: https://www.amazon.com/Geoscience-Handbook-Data-Sheets-revised/dp/0922152845. Feel free to DM me if you have any specific questions. And have fun at field camp, it really is a great and memorable time!

Kind of expensive for what it is, but this little handbook is pretty, well, handy.
