1906 San Francisco in Ruins - Zoomable!

Man, I hate to bring folks down, but take a look at this - the USGS has rephotographed George Lawrence's famous photo of the ruins of San Fran taken just a few weeks after the famously apocolyptic 1906 earthquake. Super high resolution and completely zoomable, it is really a pretty amazing piece of work. Show More Summary

Sandy Troughs!

All this nice weather is makin' me hanker some field work! Instead, I wither away, chained to the ol' Word Processor, processin' words. Oh well.However, a few of us grad students were recently able to slip off for a little local rock hammering. Show More Summary

Real Time Wind Map!

Whew! Kinda quiet in these here parts, on account of my tryin' to WRAP THIS NONSENSE UP! Writing, writing, writing, and more writing, which leaves precious little time for some of that sweet sweet bloggin. Anyway, here's something totally...Show More Summary

Leap Day Soft Sediment Deformation!

Pretty busy here...lots o' writtin', lots o' workin', and even a little bit o' thinkin' going on. Anyway, I really just wanted to grab a Leap Day post, so here's a picture of some rad soft-sed deformation from the Wilkins Peak arkosic intervals in SW Wyoming. Enjoy! Back to work!

50 Most Loathsome Americans List!

It's here! The crafty bastards at the Buffalo Beast have finally released their annual list of the 50 most loathsome Americans! Go and READ IT now! Who knows; maybe you made it this year!?!

Sed Structure Sunday - Adhesion Ripples!

As previously mentioned, my visit to Sandy Hook in New Jersey was on a pretty damn windy day. Big, 40 mph gusts were walloping the beach, coming in obliquely off the sea an onto the sandy foreshore. These winds were mobilizing a LOTShow More Summary

Crab Pavement!

Day three of our "dead beach stuff" marathon here at the ol' Blog; you can catch up on all the grim action on these previous posts. Anyway, today's litore mortem comes again from the Jersey coastline at Sandy Hook. It was a blustery day, with 40 mph gusts along the shoreline, and very very very cold. Show More Summary

More Dead Things on the Beach!

Continuing the trend from yesterday, here's another picture of some dead stuff I found on the beach over the holiday break! We've moved out of the Gulf and onto the Atlantic coast, and a far bit more northward as well; these pictures are from Sandy Hook, off the coastline of New Jersey. Show More Summary

Jellyfish on the Beach

The shoreline is always a fun place to visit; not only is it a picturesque confluence of all sorts of sedimentary and geomorphic processes mingling and interacting with on another, but there's all sorts of wiggy critters and nifty biology to see as well. Show More Summary

Steno on Google!

Jumpin' Cats! Take a look at today's Google Doodle thingy...it's Nick Steno's 374th B-Day, and they've got a cartoon in honor of it! Neat-o! Steno has, of course, been mythologized as one of the fabled "father's o' geology", most often remembered for his "three Laws": Original Horizontality, Lateral Continuity, and of course Superposition. Pretty nice exposure!

Desert Horned Lizard!

A quick picture of some more neat-o herpetofauna! This one is a desert horned lizard, from the Valley of Fire State Park in Nevada. Pretty slick camo, eh?

Privilege, Equality, and Disparity: A Link To A Totally Rad Essay

I just wanted to quickly point out a really excellent essay that does a killer job deconstructing and exploring the (sometimes stealthy) role that "privilege" has in creating disparities between folks. The essay, titled "SacrificingShow More Summary

Evaporite Casts in Sandstone

I've been working, as part of the ol' PhD rigamarole, in the Wilkins Peak Member, which is part of the Eocene Green River Formation in southwest Wyoming. Anyway, this part of the world during the Eocene was characterized by extremely...Show More Summary

Ophiomorpha in core

Trace fossils are, as I've said before, pretty rad. As a sed/strat type, I mostly appreciate them for their utility in paleoenvironmental reconstructions, their ability to help us constrain substrate conditions, and the help they can give us in interrogating rates and processes of sedimentation.

Burgess Fauna Zapruder Film

Here's something to start the day off RIGHT! A little movie, from the Royal Ontario Museum, showing a catastrophic mud-rich turbidity current sweeping over some poor Burgess Critters! They've even got the ol' cinematic rumble going on! Poor little Anomalocaris!

Lower Mississippi Valley Geomorph

Google informs me that it is ol' Mark Twain's 176th Birthday today, so a quick post pointing out some pretty nifty Mississippi River research seems appropriate today. The Army Corps of Engineers has a pretty nice Lower Mississippi Mapping...Show More Summary

Rocks at Dawn!

Busy busy busy! Just a quick post with some more pretty pictures from out west...let the glow of dawn light on the fluvial/alluvial Cathedral Bluffs keep you warm on these wintery days! Interbedded sandstones (of both the channelform...Show More Summary

Channelform Picture #3241 - Cathedral Bluffs

Cold and dreary November days call for cheery remembrances, so I thought I'd share one with you: a spiffy little single-story, lateral-accretion dominated channelform from the Eocene of southwest Wyoming, truncating some mud-rich overbank/floodplain deposits. Man, I have a LOT of pictures of channelforms...

Frickin' Fracking...

Our intense and escalating addiction to sweet, sweet hydrocarbons combined with our collective paranoia about dependency on foreign oil (damn you Canada!) has driven some pretty clever advances in the petroleum geosciences. Whether in...Show More Summary

Armored Mudballs!

"Quiet water conditions" is the depositional mechanism most often evoked to explain the presence of fine-grained mud in the rock record. Mud, generally made up of clay minerals, is defined on the Udden-Wentworth grain size scale as particles smaller than ~0.00015 inches, or around 0.003 mm. Show More Summary
