Delicate Arch, with a dusting of snow, as the sun sets.

A great reason to live in Moab, Utah, or visit there.

Rocks on the right can also be seen in this photo; can you help pinpoint the location of the photographer, and names of any of the other formations?


Annals of global warming: Great Lakes need water

Does Lake Michigan's record low mark beginning of new era for Great Lakes? At least 150 years of rhythmic pulses in Lake Michigan's water levels appear to have shifted abruptly with loss of winter ice.   Photo by Mark Hoffman, Milwaukee Journal-Sentinel

Don’t get complacent, yet.  Has enough water fallen in the Great Lakes drainage area in the past six months to change this situation at all?  From the New York Times last June:

Drought and other factors have created historically low water marks for the Great Lakes, putting the $34 billion Great Lakes-St. Lawrence Seaway shipping industry in peril, a situation that could send ominous ripples throughout the economy.

Water levels in the Great Lakes have been below their long-term averages during the past 14 years, and this winter the water in Lakes Michigan and Huron, the hardest-hit lakes, dropped to record lows, according to the Army Corps of Engineers. Keith Kompoltowicz, the chief of watershed hydrology with the corps’s Detroit district, said that in January “the monthly mean was the lowest ever recorded, going back to 1918.”

While spring rains have helped so far this year, levels in all five Great Lakes are still low by historical standards, so getting through the shallow points in harbors and channels is a tense affair.

It’s not just storms, rising sea levels, and melting glaciers, you know.

Devils Tower is beautiful in autumn

October 25, 2013

Or any other time of year.

From the Department of Interior Twitter feeds:

US Dept of Interior ‏@Interior 16h Is there any doubt fall is best enjoyed in America’s great outdoors? Here’s great example from Devils Tower NM. pic.twitter.com/YRo1U8DSMQ

What do you think Richard Dreyfus thinks when he sees that?  Stephen Spielberg?

Devils Tower NM” means “National Monument,” not New Mexico.  This volcano remnant stands in Wyoming.

Old friend, painter and photographer Nancy Christensen Littlefield offers a more close-up view.

And looking even closer, you spy Richard Dreyfus never-wanna-bes:

Climbers on Devils Tower. Photographer Nancy Littlefield said: “There were Native American prayer bundles along the trail around the base. It really is awe inspiring. Early morning gives you the best light to photograph it by.”

Devils Tower is the plug of an old volcano.  What’s left is the magma that hardened, and what we see is left after the softer cone eroded away.

Is your science class as smart as a U-Haul truck?

October 23, 2013

We had to fight to keep this stuff in Texas science books.

Then, out on the street, I see a U-Haul truck.

U-Haul truck features geographic information, and geology information

U-Haul truck features geographic information, and geology information, about Arkansas and its Crater of Diamonds State Park.

Detail:  U-Haul truck features a graphic description of the geology and information about Arkansas's Crater of Diamonds State Park.

Well played, U-Haul.  Can Texas catch up?

Update, October 24, 2013:  Turns out U-Haul has a website that features all of the graphics they use on their trucks.  I sense a geography or state history assignment in here, somewhere, social studies teachers.  Reminds me of the animals that used to (still do?) grace the tails of Frontier Airlines airplanes, the Native American on the tails of Alaska Airlines, and other specific destination promoting tricks businesses have used over the years.  Wish more businesses would do that.

Twitter open thread: Noah’s flood

July 30, 2013

No, the evidence doesn’t point to a Noachic flood.  Evidence contradicts the idea.

Welcome, @crazy_stairz @EdDarrell @paulmc107 @StrangerGirl2 @HomunculusLoikm @LogicBobomb, and anyone else who wants to join in.  Usual rules of civility apply.

Discussing this, and its many cousins:


What rocks Yosemite? Granite

July 7, 2013

Yosemite’s Nature Notes #20 (I’m behind):  A short film discussing the astonishing manifestations of granite in Yosemite National Park.

English: El Capitan in Yosemite National Park ...

El Capitan in Yosemite National Park viewed from the Valley Floor — one of the more famous granite formations in the Park. Wikipedia image

The film is simply named, “Granite.”  Steven Bumgardner produced the film.

Yosemite’s chief formations are granite, an igneous rock.  Much of the terrain was carved in the granite by glaciers and glaciation — so what Yosemite shows is how fire and ice combine to make rock, to make rock formations, and to make rocks of astonishing beauty.

(This is not a place to bolster creationist ideas.  This is real science, looking at God’s handiwork first hand.)

A North Carolina university makes field trips to Yosemite?  I’d love to take that class!

Watching this film, you get a sense of how important it can be to the education of our children to travel in the summers, to take vacations to our National Parks, and to places like Yosemite.

Where are you taking your kids this summer?  Kids, where are you going?

Enjoy it.  Geology lessons are often fun, and this one, on film, is more fun than most.
