This post unifies two of my absolutely favourite topics: geology and classical Greek history. I have always had a soft spot for the classics. In fact, when I started my undergrad I was planning on...

The 184 diamonds in the Seahawks Super Bowl Championship rings can tell us a thing or three about Earth’s inner self. We’re still interrogating those valuable, shiny rocks (which...

One of the most fascinating things about geology is its ability to reveal global events from evidence contained within a single outcrop. The cliff exposure at Aust in Gloucestershire, UK, is a spectacularly colourful example of this. Located beneath the original Severn Bridge, and running alongside the Severn Estuary, the 40m tall rock face records
Jul 13, 2014, at 1:55 PMHello,My name is Ross [----] and I will be a senior at [----] High school in Missouri this year. I am considering either geology or geophysics as a major for college. I am specifically looking for guidance regarding the future job outlook for both of these careers in the next 20 years. I am also considering majoring in petroleum engineering and need some insight about the advantages and disadvantages concerning this career compared to geology/geophysics. Also, [...]
The most important lessons drawn from geology are that the earth’s climate can change radically and that the pace of change can be rapid. The precision of measurement is currently too poor to give an exact answer to a critical question, At what carbon dioxide level are we in danger of melting Antarctica? However, while crude, these estimates suggest that this threshold will be reached in 150-300 years, if carbon dioxide levels continue to rise at the current
“Swamp gas?” Mulder, F.W. in the “X-Files ” (1993) Summer is traditionally Silly Season, when newspapers publish strange stories about aliens and monsters again and again to bridge holiday time – and so will July on “History of Geology” be dedicated to frivolous science stories… Earthquake Lights – or short EQLs – seem to be
My favorite waterfall in Montana is Natural Bridge Falls, located on the Boulder River, south of Big Timber. At high water—such as in this photo taken this spring—some of the water flows over the top of the cliff, while a considerable part of the flow comes out of caves in the side of the cliff.
“With regard to precipitous heights, if you are beforehand with your adversary, you should occupy the raised and sunny spots, and there wait for him to come up.” The Art of War, by Sun Tzù The battleground of Gettysburg was shaped by ancient tectonic movements, sediments transported by rivers and deposited in lakes and finally
A small town in Wyoming, Kemmerer, is touted as "An Aquarium set in stone" due to it's proximity not only to Fossil Butte National Monument but also to a bunch of other fossil hunting locals in the region. While we were staying there we wandered around in the center of town (home to the first J. C. Penney Store). Outside the storeInside the storeHowever, I noticed that where all of the sidewalks dip down to the street around the park in the center of town (across the street from the J. C. [...]
In Current Science K.S Valdiya explains (Open Access):
It will be obvious from the distribution of dam locations (Figure 1; Tables 3–6) based on information culled from reports of Central Electricity Authority, Uttara-khand Hydroelectricity Nigam, Uttarakhand Renewable Energy Development Authority, etc. that the existing hydroelectric projects and those that are under construction or
When I plan subcontracts, there are generally two ways that I prefer to pay for the work: by the unit of x produced, or by time spent. For drilling, most of the time, I prefer to pay by the foot rather than a day rate.
The footage rate is a performance basis. If the driller brings equipment prone to break down or encounters problems with the geology and can't go as fast as he'd planned, then
“Hence the saying: If you know the enemy and know yourself, your victory will not stand in doubt; if you know Heaven and know Earth, you may make your victory complete.” The Art of War, by Sun Tzù In 1863, after more than two years of Civil War, the Confederate Army of Northern Virginia launches

And that's something that I really love about science and geology: the acknowledgement that there are things we don't know...yet. No matter how ingenious our technology becomes, no matter how much data we collect, there will always be new things to discover, and each week research reveals something new about our Universe that no one has ever known before. And that's the fun of exploring a
A great video short that talks about Utah’s expansive fossil record and dinosaur findings due in part to our wide variety of geology. Watch it to find out more about Utah’s contribution to dino
Whenever I go to a hearing on the Senate side of Capitol Hill, I usually arrive via Union Station. It's a really beautiful building and one of the few grand train stations left in the country, and I'm always impressed by the architecture there. According to the architectural history, it was designed in the Beaux-Arts Style and meant to mimic the Roman Baths of Caraculla and Diocletian. It was completed in 1907, and then restored from 1986-1988 (and it's actually being worked on right now, too). [...]
Spirifer consobrinus is a fossil that is confined to a specific strata within the Windom shale at Penn Dixie and 18 Mile Creek in New York. It's a small brachiopod that resembles Mucrospirifer but has a much shorter hinge line and a larger interarea on the pedicle valve. The pedicle valve's "beak" is also recurved more strongly. It has taken me a few years to really figure this out and I only have a handful of decent specimens.Specimen #1Specimen #2Spirifer consobrinus is well documented in [...]
While the majority of geoscience blogs is in English, I personally have the feeling that Spanish must be the second most popular language in the geoblogosphere. Videoblogs are not so numerous, but there are some really good ones out there. … Continue reading
