Geology Field Photo: Bryce Canyon Hoodoos

A hoodoo is an erosional feature, a tall column of rock that has been left behind after the rock around it has been worn away.  Bryce Canyon National Park, Utah, has some spectacular hoodoos.  They form when an upper layer of rock is more resistant than the layers below.  Consequently once the top layer is removed by erosion, the other layers are removed quickly, leaving tall remnant spires.  Although referred to as a canyon, Bryce Canyon is really more of an amphitheater-shaped depression, formed not by a river carving through it but by erosion processes at the heads of small streams.  The orange and white rock layers here are part of the Eocene age Claron Formation.

I spent over a week one early May camping at Bryce Canyon, and driving along the rim, walking down in.  Up before sunrise, and past sunset, to see all the varying effects of light on the hoodoos.  An amazing place.  I hated to leave.  Great photo, +Charles Carrigan

Geology Field Photo: Garden of the Gods & Pikes Peak

The mountains are calling, and I must go.  John Muir

Going through some more of my old shots from back in the "spray & pray" days, and found this one from near Garden of the Gods near Colorado Springs, CO.  As in many places along the Front Range of the Rocky Mountains in CO, the sedimentary rocks are tilted upward at steep angles from the uplift of the mountains to the west.  Here again it is the Pennsylvania Fountain Formation forming the red sandstones jutting up toward the sky.  In the distance is Pikes Peak, the highest summit in the southern Front Range at over 14,000'.  Pikes Peak is part of the Precambrian rocks, composed of ~1000 Ma granite.  The Fountain Formation sandstone is composed of eroded material from Pikes Peak granite and other nearby Precambrian rocks, which were laid down flat ~300 Ma when the Ancestral Rocky Mountains first arose.  Those old mountains were cut down completely flat by erosion, however, long before the modern Rockies began to rise in their place.

Video on Wegener  

Today's +The New York Times has a short op-doc article & video on the life of Alfred Wegener, who pioneered the idea of continental drift 100 years ago.  A Meteorologist by training, his ideas were revolutionary but poorly accepted by the geoscience community at the time.  Nonetheless, his work was fully vindicated by the 1960s, several decades after his death, with the widespread acceptance of the theory of plate tectonics.  It was 50 years ago (coming up this July) in 1965 that J. Tuzo Wilson published his monumental work "A new class of faults and their bearing on continental drift", which was for many the culminating paper that really fleshed out the new theory.

Geology Field Photo: Abe Lincoln up close

Today is Presidents' day here in the US, and I thought I'd share a photo from Mt. Rushmore.  Mt. Rushmore is carved into the Harney Peak Granite, a large granitic pluton that intruded the metamorphic rocks of the Black Hills around 1700 Ma.  Looking in detail above Lincoln's left eye, several cross-cutting dikes within the Harney Peak granite are seen; these are likely the last gasps of melt that crystallized very late as this large magma body was slowly cooling. 

This also marks 50 photos added to my Geology Field Photos album - here's to 50 more, Mr. President!

Climate Change  - 
 
A new study predicts unprecedented droughts in the American west and Great Plains in the next century due to climate change.  Perhaps Steinbeck will come back and write a sequel to The Grapes of Wrath after the dust bowls of the future.  

H/T +Vicky Veritas 
 

I couldn't quite say it out loud when I wrote this post, but here's a really scary study.
Our best climate models, combined with our best climate records, foresee at least a century of profound drought in the Midwest and Southwest.

Wow!!  Read below on how +John Chumack  obtained this incredible image of the Andromeda galaxy.  
 
Into the Heart of the Beast! Ever wonder what is deep inside the bright Core of M31 The Andromeda Galaxy?
Here is my attempt to image past the overwhelming bright central glow of the Galaxy &  to peak into the core to see all those dusty lanes, stars, & gas Spiraling into the central 100 million solar mass Black Hole.
The double nucleus, recently discovered by Hubble, was found not to be two black holes as some first speculated. The double nucleus is actually an elliptical ring of old reddish stars in orbit around the black hole,
When the stars are at the farthest point in their orbit they move slower, like cars piled up on a crowded freeway. This gives the illusion of a second nucleus.
I took 60 minutes worth of various short exposures ranging from 5 seconds to 2 minutes and layered them in Adobe to cut through the bright light to try to see the details in the core. I've been working on this on and off since Sept of 2014, and finally finished the processing last weekend.
M31 is Our Sister Galaxy, Closest spiral to us at 2.5 Million Light years away & contains over 1 trillion stars. M31 Andromeda is visible to the unaided eye from a dark location. M31 The Andromeda Galaxy and our Milky Way Galaxy
will experience a Galactic Collision in about 4 billion years.
Attached is an Image I  captured with a QHY8 cooled Color CCD camera, and my Home-built 16"diameter Newtonian telescope, from my observatories at JBSPO in Yellow Springs, Ohio 09/19/2014.

Best Regards,
John Chumack

Planetary Geology & Meteorites  - 
 
Not exactly geo, but this is a pretty interesting study.  A reconstruction of a red dwarf's trajectory indicates that it passed within 0.8 light years of our sun ~70,000 years ago, picking up a few comets from our Oort cloud along the way!  They say that even at that distance, this tiny star and its brown dwarf companion would not have been visible in the night sky, which makes me wonder how close it would have to be to be seen at night - or during the day?  
Astronomers say a red dwarf star and its brown dwarf companion passed within a light-year of our own sun 70,000 years ago, moving through the comets in the o...

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!

Introduction
I'm a Professor of Geoscience at Olivet Nazarene University.  I'm a big fan of hiking, camping, & other outdoor activities.  I'm also into photography, technology, culture, politics, psychology, sociology, education, the interaction of religious faith with the above, music, games with friends, cooking, yadayada.  

On Google+, I post geology field photographs I have taken about once a week and give a brief explanation of what you are seeing from the eyes of a geologist.  These are kept in my album "Geology Field Photos".  I am also the owner & a moderator for the Geoscience Community here on G+, and I hope other geoscientists will join the discussions there.  
I sometimes write a blog about mineral resources & the environment & anything else geological I feel like called Earth-like Planet.  Circle me here on Google+ if those things sound of interest to you.  
Professionally, I study the application of mineralogy, petrology, & geochemistry to the understanding of mountain belts and tectonic processes, specifically in the Southern Appalachians.  My students and I use the tools of geochronology and thermobarometry to establish P-T-t paths of metamorphic rocks, and thereby constrain the timing and rates of tectonic processes.  Our current, ongoing project focuses on information that can be obtained by emphasizing the study of rutile & other minerals in pelitic schists.  

I also study the best practices for improvements in education within the MPG (mineralogy, petrology, & geochemistry) disciplines, as well as geoscience for general education.  My work has focused on a complete redesigned the way I teach mineralogy with an emphasis on geologic context, as well as the way students relate upper level course work back to material and skills they learned in previous courses.  I'm also in the process of designing video tutorials for optical mineralogy, which I hope to begin publishing on the web in the next 6 months.

Nice place, but really expensive. The price is way too high for tent sites.

There's lots to love about this park. The trees are wonderful in the fall. The stars are incredible at night! The camp sites are decent, with good fire pits and picnic tables. They could use some flatter tent pads in some areas. Some of them have really poorly designed drainage and one site we stayed at was very muddy. But as much as I love this place, I have to give it three stars for two reasons. First, the water quality issue. I've stayed at this campground many times over the past ~15 years, and the water always has a boil advisory. They really need to fix this and get clean, potable water that is safe to drink. I've never had a problem, but it is a risk that shouldn't be tolerated anymore at a Provincial Park. Secondly, the price of these sites is absurdly high. It costs ~$35+ per night just for tent sites. That's way too high for a spot to set up a tent esp. when the water can't be trusted.
