"The lateral blast of May 18 was indeed an awesome event by both human and geologic standards, and certainly dwarfed that of the water jet pack!"

In geological terms, a contact is the place where two different types of rocks come together. This ezine is a place to find content from my favorite web sources on the the creation-evolution issue, with a focus on the subject of geology. Just as the layers of a rock can be composed of many different materials, so my sources often differ in their assumptions and in their views on the issue, but their common intersection is the belief that this is an important subject.

There was the Jehol biota (Cretaceous), with its "feathered dinosaurs," but now the "prequel" Daohugou biota (Jurassic) is opening eyes wide again.
David Coppedge dissects an open access paper on the important Daohugou bone bed.
Wikipedia also has a very interesting overview of the problematic Daohugou formation: http://en.wikipedia.org/wiki/Daohugou
"There is a lot of really interesting reading in this issue, as there always is. It’s a journal for people who want a bit more meat, and to see what creation scientists are discussing and debating."
Includes articles on fast growth of desert varnish, criteria for determining Flood boundary in specific areas, and the meaning of the Great Unconformity and the Sauk Megasequence.
"Geologists say the study raises serious questions about a supposedly reliable test. “People are recognizing that we have to be more careful,” says geochemist Timothy Lyons of the University of California, Riverside. “We need to increasingly focus on doing just what [these authors] did, a more careful characterization of samples.”
Always a need to be careful when relying on proxies, especially for age determinations.
"The National Aeronautics and Space Administration has begun deploying 28 toaster-sized satellites built by a Silicon Valley tech company that will monitor the earth faster and more completely than ever before."
Will Google buy these images?
A creationist interpretation of a fantastic fossil find.
"More and more academic papers that are essentially gobbledegook are being written by computer programs – and accepted at conferences."
Funny! Probably more difficult to carry off in geology, but not inconceivable.
"History in These Streets is a virtual recreation of the Black Panther Legacy tour that the Huey P. Newton Foundation conducts in West Oakland. The tour includes an audio narration by David Hilliard, the former Chief of Staff of the Black Panther Party. As Hilliard relates the history of different locations the Street View of that location is displayed, with a little help from the Google Maps API."
This might be an interesting way to create virtual geology field trips along highways with important outcrops.
"Northern California's Folsom Lake, above, on Jan. 16, 2014."
Scroll down to see the reservoir in 2011. Pretty spectacular drop.
"My husband and I were watching some apocalyptic group building an underground shelter on TV, and I remarked that living underground is quite cozy and pleasant -as long as you have ready access to the outside (of course, being trapped is a nightmare). My father was a geologist, and I grew up in cave country, so I find that being underground is like having Mother Earth wrap her arms around you. There are plenty of places where you can stay temporarily to find out if you feel the same way."
For your inner troglodyte.
The evidence is now in and despite weeks of official denials it's a definite "Yes."
If true, this piece is a definite eye-opener.
A deep freeze has settled in over the Great Lakes this winter and a new image released by NASA shows the astonishing extent of the ice cover as seen from space. NASA's Aqua satellite captured this image of the lakes on the early afternoon of Feb. 19, 2014. At the time, 80.3 percent of the five lakes were covered in ice, according to the Great Lakes Environmental Research Laboratory (GLERL), part of the National Oceanic and Atmospheric Administration. Earlier this month, ice cover over the Great Lakes hit 88 percent for the first time since 1994.
Each of these lakes represents a former glacial lobe. Interesting that some are almost completely covered and some aren't.
"In 1849, railroad workers in Charlotte found a skeleton that helped piece together Vermont’s geological history. The unlikely discovery of what’s come to be known as the Charlotte whale, and the scientific boon it lead to, is chronicled in a new book by Jeff L. Howe called How Do You Get a Whale in Vermont? The Unlikely Story of Vermont’s State Fossil."
Interesting tale. The article isn't quite clear on how the whale got to its fossil location. Best I can figure out is that Lake Champlain was part of a waterway that extended to either the St. Lawrence seaway, or Long Island Sound, or both.
"Prolific creationist author Michael Oard is known for his extensive literature research and cautious but thorough reports. His new book on dinosaurs achieves more than its title suggests, and does so in a surprisingly readable format. Not only does it present dinosaur challenges and mysteries, but solves them—or at least presents a solution that best fits the facts."
"There are plenty of reasons to ask for a window seat. For starters you can lean on the window if you want to sleep, and you never have to get up for someone else! But it’s what’s outside of that window that is most compelling."
It's kind of like Google Earth, except it's real. Like earth Earth.
" What causes sinkholes? A glimpse at this fascinating map of Kentucky groundwater flow routes confirms the well-known fact that sinkholes are not uncommon there, given features with such names as "Sinking Creek", "Auburn Bluehole," and "Lost River Rise."
The facts behind the recent collapse of a passel of Corvettes into a sinkhole.
"Over at Google Earth Blog, Frank Taylor nails an issue I've noticed too: support for Google Earth and development of the product seems to have dropped off Google's todo list. Frank interprets this as being a bad sign for the future of Google Earth and I think he's right."
The blogger laments "stuff educators would miss" if GE goes away as a standalone.
It's not just educators--I think this would be a tremendous blow for geoscientists as well.
"His insights, before the advent of satellite mapping and GPS, paved the way for the waves of map-making innovations that followed."
Mr. GIS--what a debt we owe this man.
Quote: “Don’t worry about what’s in it for you,” James Boxall, head of the GISciences Centre at Dalhousie University, said Dr. Tomlinson once advised him, “worry about what you’re giving back.”
"A 65-foot crack in a Washington dam has investigators worried whether it could cause a breach."
Well-supported evidence for one single Missoula megaflood.

At least 40 baleen whales and other species of marine mammals fossilized in a dry desert of Chile have been explained with a "toxic bloom" theory. Does it explain all the findings?
Among other questions, David Coppedge asks how the carcasses could have escaped scavenging and decay, and why they are located on the edge of the Atacama desert, one of the driest deserts in the world.

"Two earthquakes greater than 5.0 have rocked the Caribbean in the last week and concerns have been growing for a major tremor in the region."
The recent storms that battered the UK have offered a glimpse into the past of the Welsh coastline, by washing away peat and revealing the stunning remains of ancient forests.
"Legend has it that the region was home to the fertile kingdom of Cantre’r Gwaelod, or the Sunken Hundred, that was lost under the sea when Seithenyn, one of the two princes guarding the area got drunk, and left the area prone to the floodgates of the sea."
PRESTONPANS is buzzing with the news, as reported in the Courier, that the legendary Johnny Moat has fallen.
The story of a glacial erratic whose fate has been tied to the fate of a town.
"Most legends are about faraway places, or things we read about in books or watch in a movie. But in Prestonpans the local legend gives pride of place, a sense of belonging, a connection to a landmark that defines home.
So the fate of this stone does matter! It is layered with generations of traditions and provides a subliminal feeling of safety and continuity with the past.
And if you think it is nonsense that the well-being of a community could be emotionally attached to the fate of a stone, then just go to Edinburgh Castle! There you will see on view a much less impressive stone. Yet it is guarded as a priceless treasure, and is exhibited with the Scottish Crown Jewels.
They call it the Stone of Destiny, or also the Stone of Scone. It also has a legend attached to it, and that legend states that a monarch can only claim to be a true monarch of Scotland if they are crowned while sitting on the stone. So for 700 years this rather unremarkable stone has been an important part of the coronation ceremony of English and then British monarchs."
