Thanks for responding. I have a whole photo-tour of the Buttes on my About.com site

Mary Beth:
Those lone buttes on the way to Chico are the “Sutter Buttes” – An old eroded volcano. It is the southern point of the Cascade Range, which includes Shasta and Lassen. These mountains extend north to Oregon and Washington State.

I want you to come and live with me and do a running commentary on the geology in my life. I am SO grateful whenever anyone can tell me something about the geology of a area. Like why are those lone buttes on the way to Chico? and why is the dirt red in Redbluff and Redding and nowhere else? What are those yellowish grayish rocks in the clay in my back yard that shatter so easily? You get the picture. You would have to move to San Mateo…

“Glaukos” means blue-green or simply gleaming. Minerals and rocks with glauc- in their names are blue or green.

I thought glaucus meant white, not blue.
