Jeez, Missouri used to put out State Geologist trading cards. I'm so jealous!  This is Raphael Pumpelly, MO St G from 1871-1873. The back of the card says he did big studies on mineral resources, but retired because of health problems. It also notes a shopkeeper in Pilot Knob complaining he was still owed $5 by the state for cabbage Pumpelly purchased. JFC, how much cabbage would five bucks have bought in 1871? The guy must have been spoiling his mule ~

We made it, just in time.
Generally, “February” and “Wildcat Canyon” are not words you hear in the same sentence around southwest Utah, except for maybe in this sentiment: “Wildcat Canyon? You can’t hike there in February. There’s too much snow!” Or p...

Geology Field Photo: Folds in Cambrian Rome Fm.

These folded layers are found in the Rome Formation, part of the Cambrian rocks in the Southern Appalachians.  Just up the road (to the west) is a great roadcut of the Copper Creek thrust fault, one of the major thrust faults in the Tennessee Valley & Ridge.  The Cambrian Rome Fm. is thrust up and over younger Ordovician rocks; here in the hanging wall the rocks also experienced ductile deformation.  These folds are asymmetric and west-vergent, as would be expected with thrusting coming from the east (to the right in this photo).  Happy Friday everyone!

The discovery of a slippery layer off the coast of New Zealand could help explain plate movement

Aquamarine on muscovite at the Tucson Gem & Mineral Show. You could buy a car for what this gorgeous specimen costs (see the tag)!

This looks like a thin section of a metamorphic rock!

Geopic of the week:  Don't be a square, check out these joint sets!
Here is a photograph of Pitkin Limestone from the Ozark Mountains near Fox, Arkansas.  This exposure displays a classic orthogonal joint set.  The joints are the easy-to-see fractures tha...

Overrun with visitors during the summer, with hardly anyone on it now? Just another February day in paradise.
I have never met a trail in Zion National Park that I did not like. Long, short, steep, level, paved, rocky, hard sandy slickrock or soft forest soil, it does not matter. I will hike wherever and whenever the opportunity pres...

A drive along the Causeway Coastal Route of Antrim, Northern Ireland.  This this one of the world's most beautiful coastlines and makes an amazing road trip.

More gorgeous mineral specimens from the Tucson Gem & Mineral Show. No, I can't hold a camera phone still enough to take a non-blurry photo.

Geopic time!  Who likes Archimedes screws?
This is a picture of weathered fossiliferous limestone of the Pitkin Formation.  It was taken in a quarry near Batesville Arkansas.  The picture displays fossil remains of two common aqua...

Geology Field Photo: GIANT Sigma Clast

The large white grain here is a very large sigma clast from the Southern Appalachian Blue Ridge.  This sample is located in one of the shear zones of the Eastern Blue Ridge between the Cowrock and Cartoogechaye terranes.  These rocks are exposed in a very large roadcut on Chunky Gal Mountain - some interesting place names down there!  A sigma clast is a large grain that has been sheared by deformation.  The asymmetrical tails coming out each end indicate the directions of shear movement; the motion on this one is top to the right.  This is by far the biggest sigma clast I've ever seen.  Numerous other grains, much smaller than this one, can be seen in the thin layers above it and to the right.  Estwing hammer head for scale.
