I spent the weekend camping "in the field" in some of the mountains of Norther Cal. Near Mt. Lassen (an active volcano) Here are a few quick pics of some of the geological structures I looked at.


On the right of the picture you can see columnar jointing
And on the left you can see Pahoehoe Lava flows


Here is a better pic of the igneous columns. Geology Rocks!


Here is a pic of a dormant Cinder Cone; a type of volcano. The boulders at the base of it are as big as a man to give you size reference.

Ok class that ends today's lessen. Tomorrow we will address the effects of chemical weathering.

 

This is better than the Discovery Channel...with trucks! Thanks for sharing the experience

 

I've hiked lassen. There is some beautiful country up there.

Were you around Almanor at all?

 

Wow I didnt realize the pics were so big until now. I used someone else's camera with my SD card. To be nice I didnt change any of his setting but dang those are big. I didnt have enough room on my SD card to fit anymore pics of the stuff I saw. Like some great tufa mounds and some great quarts lined schists.
