Today seems like a good day to take a virtual trip over to Arizona Geology, the blog of the State Geologist of Arizona. To find out about Lee Allison, the blog's author, State Geologist and Director Arizona Geological Survey, and his reasons for starting Arizona Geology, see his first post on January 1, 2007. It is entitled Arizona lives and dies by its geology.
You may actually want to go back and browse all of the posts. There is a lot of extremely interesting information in these blog archives. For instance, Basin & Range aquifers 4th most heavily used in nation is a very welcome post.
I've added Arizona Geology to The Conconino Chronicles' Blogs of Note in the sidebar.
