Cross-bedded ash layer at Badlands Natl. Park

A mixture of igneous & sedimentary processes were at work in this cross-bedded ash layer at Badlands Natl. Park. The layers of rock in the Badlands are dominantly sedimentary rocks deposited by ancient streams, but there were active volcanoes at the time contributing significant amounts of ash as well. That ash was frequently reworked by streams after eruptions, forming layers like this one: it is made of volcanic ash but got in its present state by being transported and redeposited by water.

I've finished a blog post at my website on the geology of Badlands Natl. Park, where you can find this and other images of geologic features: http://charleswcarrigan.wix.com/geoscienceimaging#!Geologic-Features-at-Badlands-Natl-Park/cf15/577b34f90cf2119db9ca3170

NASA Rover Findings Point to a More Earth-like Martian Past
Chemicals found in Martian rocks by NASA's Curiosity Mars rover suggest the Red Planet once had more oxygen in its atmosphere than it does now.

A new computer algorithm that can “fill in” underground water levels in areas where quality data is not available could lead to improved models of groundwater flow in regions where pumping and aquifer depletion are a concern.

Badlands Natl. Park, looking E from Sheep Mtn.

Young rocks, geologically speaking (~35 Ma), being very quickly eroded. This area of the park is not well developed; to get here requires a vehicle with high clearance! Most visitors to the park stay on the much better developed northern area. Nonetheless the views here are very rewarding. These are Oligocene rocks formed by stream deposition and volcanic ash, now being eroded away by streams cutting through the area. Streams that used to feed this area with sediment from the eroding Black Hills to the west were captured by headward erosion of the Cheyenne River, which flows to the NE away from the Badlands.

Bal Gangadhar Tilakan, the legendary Indian nationalist, teacher, social reformer, lawyer and independence activist wrote in The Arctic Home in the Vedas: “The geologist takes up the history of the earth at the point where the archaeologist leaves it, and carries it further back into remote antiquity.”
 
Now…. I am not one to take exception with Bal Gangadhar Tilaken and to what he said, after all he is a great historical figure…however in the field of geo-archaeology the geologist takes up looking at various cultures and civilizations to unravel and understand the role that natural resources, i.e., geology, geomorphology, climate, etc., played a part in the sustainable development choices and in the daily lives of prehistoric cultures.
 
 
Before I took up geology as my true chosen profession and passion I was very interested in archaeology and minored in the subject in undergraduate school.  I worked several summers in the field doing various geo-archaeological studies for the Paleo-Indian Institute at Eastern New Mexico University under the tutelage of my mentor and friend Fred Nials.  Most of this work was along the Rio Puerco de la Este, in Central New Mexico where there were hundreds of Anasazi (“The Ancient Ones”) ruins.  And I spent the summer between my undergrad work and grad school as the Site Geologist at Salmon Ruins, a Chaco ruin in Northwest, New Mexico.  I then began doing petrographic analyses of the tempering material used in pre-historic Indian pottery and helped support my way through undergraduate and graduate school doing this for the Cultural Resources Management Division and NMSU and for the Centennial Museum at UTEP.
 
 
Before all this school...my interest in archeology was largely driven by the fact that I grew up in Clovis, New Mexico just a few miles from the Blackwater Draw site where spear points of Alibates flint was found embedded in skeletons of Mammoths.  I actually worked there for one semester before I was invited by the President of the United States to join in a little soiree he had going on in SE Asia (Vietnam).  Upon return from this interesting hiatus in my life I returned to my studies and found geology a good addition to my interest in archeology and I developed a lifelong passion for geology eventually majoring in geology (that was an economic decision…LOL). 
 
Anyway, a good example of how geology is used is in studying the resources used by the earliest paleo-indians for their tools, in particular the material used for spear points.
 
The rest of this post is dedicated to looking at some of the beautiful Alibates flint as well as the Edwards Limestone Cherts (the same Edwards Limestones that the ammonites in my post come from).

Prehistoric asteroid wiped out nearly all mammals as well as dinosaurs, research suggests
Nearly every species of mammal was eradicated by the prehistoric asteroid which wiped out the dinosaurs, research suggests. Around 93% of mammal species were made extinct by the strike, which took place in the Cretaceous period, more than 66 million years ago. Examination of fossil records by scientists from the University of Bath determined that the asteroid's impact had been much more severe than previously thought.

Story
Introduction
I'm going for my Master's in geology. I also make stuff and I'm constantly learning new ways to do things. My homeland is the (BC) Rockies and there's no place I'd rather be. I like to listen to other people's stories and I laugh at dumb jokes. 
Bragging rights
I flew a glider over my house. I've been to, and done research on, the rift valley in Africa. I wrote a crappy novel when I was 16. I've seen a shuttle launch in person.
