An inconvenient set of facts...

This stands in stark contrast to predictions that global warming would increase storm frequency and intensity. Hmm, and I thought the debate was over.

"Quinn expects the winter of 2009-10 to produce about 25 inches of snow in places like Cheney. 'That’s half to less than half of normal snowfall at lower elevations,' he said."I'd warn you, however, not to bank on this. EWU geography professor Quinn was in error by more than 100 percent in his forecast for last winter when the Spokane region received nearly 94" of snow.

Dinosaur Museum Presents Biblical View of Origins
Hat tip: Geogal.
"We are totally different from the Museum of the Rockies in that we present fossils and all the exhibits in the context of biblical creation," said Otis E. Kline Jr., the museum's founder and director.
It's ironic that this so-called museum exists smack in the middle of an area in western Montana rich with paleontological sites that have yielded tremendous scientific information about dinosaurs. But perhaps that's exactly why it is there.Jack Horner, the curator of paleontology at the Museum of the Rockies, agrees the two museums are fundamentally different.
"It's not a science museum at all," Horner said. "It's not a pseudo-science museum. It's just not science. …There's nothing scientific about it."

will strike the lunar south polar region early tomorrow morning as depicted in the embedded video above. The impact of the spent Centaur rocket stage should send bits of lunar regolith and suspected water ice deposits into ballistic trajectories high above the crater rim to be imaged from Earth. The LCROSS spacecraft itself will fly through the cloud of debris shortly thereafter with its own on-board sensors and imagers, transmitting data back to Earth. It will also strike the Moon releasing a second debris plume, all in an effort to verify the presence of water ice.

Enjoy the full Moon...
tonight, the so-called Harvest Moon. That moniker is assigned to the full Moon that occurs closest to the autumnal equinox (22 September) when the bright apparition apparently assisted farmers during the harvest of their crops.
So take a glance, people who like to take glances.

Diggin' holes today...
at the Washington Division of Fish and Wildlife office in Spokane with members of the Northeast Chapter of the Washington Native Plant Society. The group secured a $10,000 grant to create a demonstration garden surrounding the government office.
High water use plants traditionally used in urban landscapes were excavated and replaced with water-conserving native species as shown below.

An image of Earth...
from space showing a smoky Pacific Northwest region on 19 August 2009 in a true-color image (click to enlarge.) Smoke from fires burning in British Columbia, Canada (red dots on enlarged image) obscures Vancouver Island, the Puget Sound lowland and parts of eastern Washington.
Perhaps more interesting, from a geological perspective, the channeled scablands scoured by repeated outburst flooding from Glacial Lake Missoula in western Montana during the Pleistocene appear in stark contrast against the tan-colored farm fields in eastern Washington.

Times are tough...

Heh.

Christmas comes early...
for our geochemist, Dr. C. Nezat, as she's finally secured her promised start-up monies to purchase this wiz bang instrument to support her research interests in aqueous geochemistry: ICP-OES. Congrats!
And no, despite its appearance, the sophisticated device doesn't do laundry.

Moving atoms...
one at a time. I particularly like the nanometer-scale sign that says "If you can read this you are too close."

Turbidity current unleashed...
in the sed lab yesterday morning as a demonstration for my sed/strat students. The image above shows a time series of shots taken seconds apart (click to enlarge.) Yeah, that's a chunk of kerogen-rich oil shale from the Green River Formation at the right side of the image. Read more about turbidity currents and turbidites.
I have to confess that my sand box was one of my favorite toys as a child, and it seems like I haven't really grown up.

Wise words...
When one door closes another door opens; but we so often look so long and so regretfully upon the closed door, that we do not see the ones which open for us.
