Logarithmic spiral, nautilus, and rainbow

Autumn, Western Style

Geotripper | 28 November, 2014
Sycamore at the Pinnacles National Park Visitor CenterI can't help but notice that winter has set in around much of the country, but my calendar says it's still autumn for another few weeks. I don't know why so many of you are so anxious to jump right into winter, but I'm not. As I've traveled around these last two weeks, I've seen some beautiful sights that I'm sharing as part of a feeling of thanksgiving.

field inspiration

Accidental Remediation | 28 November, 2014
My last post was sort of a long rant, so I thought I'd balance things out a bit with a more positive subject. If you do fieldwork and love being outside, (potentially) out in nature, do you have someone who gave you that love of nature? Maybe it was someone you grew up with, or a camp counselor, or maybe it was a teacher.

Geo 730: November 28, Day 697: Hood River Rubble

Outside the Interzone | 28 November, 2014
I was not able to get a good, clear photo of the lahar deposits around the river at this stop, but this is the best of them. In the little slice of whitewater right near the center of the shot, you can see some of the rounded boulders that characterize much of the upper stretch of this river. And though it's over exposed, you can see more of the poorly sorted and essentially un-bedded deposits on the far bank. Near the top, it looks as if we're seeing a talus pile from a still higher (though not necessarily younger) lava flow, based on the angular, un-transported nature of the rock, and the consistency of color and apparent composition.

IID to state of California on Salton Sea restoration: “But you guys promised!”

Inkstain (John Fleck) | 28 November, 2014
The Imperial Irrigation District earlier this month threw down a significant marker in the ongoing struggle to deal back overuse of Colorado River water with a petition to the California State Water Resources Control Board demanding action on restoration of the Salton Sea.

Geo 730: November 27, Day 696: Another Knockoff

Outside the Interzone | 28 November, 2014
Well, okay, yes, this photo is very similar to the previous one in the series, and maybe doesn't add much in the way of information. On the other hand, look at that talus pile of loose boulders behind the barrier; it has taken a lot of beating. And the fact that one of those boulders was able to knock that large chip right off the reinforced concrete is really pretty impressive. At least it was to me.

Water buffalos – embracing the pejorative?

Inkstain (John Fleck) | 28 November, 2014
I tend to hear the term "water buffalo" as pejorative - the old, lumbering water managers of a bygone era of dam-building and overconsumption. Not so, say the folks at the Central Arizona Project:

Wet Rocks and European-wide Ripples. By Carol Cotterill

Maps of wet rocks might not seem like a growth area, but BGS are currently the lead partner in the geology theme of one such multi-national endeavour. The EMODnet (European Marine Observation and Data Network) Geology project covers an area of ~11 million km2, has a budget in excess of €5 million to date and draws on expertise from every geological survey with a marine department across Europe, in a pan-European collaboration.

A clearer picture how climate change affects El Niño?

RealClimate | 28 November, 2014
I still remember the first time I was asked about how climate change affects El Niño. It was given as a group exercise during a winter school in Les Houghes (in France) back in February 1996. Since then, I have kept thinking about this question, and I have not been the only one wondering about this. Now I had my hopes up as a new study was just published on the evolution and forcing mechanisms of El Niño over the past 21,000 years (Liu et al., 2014).

Sovereign Glacier Retreat, Talkeetna Mountains, Alaska

From a Glaciers Perspective | 28 November, 2014
Sovereign Glacier is on the northeast side of the Talkeetna Mountains, Alaska and drains into the Talkeetna River. The Sovereign Glacier, red arrow, was joined by a tributary from the south in the map image, pink arrow. Molnia (2007) noted that all glaciers in the region have retreated since the early 1950's when the area was mapped and that all the major termini were retreating and thinning in 2000. Here we examine Landsat imagery from 1986 to 2014.

A Mildly Promising View of Mt. Shasta...It Has Snow!

Shasta from the vicinity of Dunsmuir from the southA short note from the highway tonight. We were on a long road trip into central Oregon today and followed Interstate 5 through northern California. One of the real treats of following I-5 is the chance to see Mt. Shasta from many different directions.

Give the Gift of Paleoart!

One of my favorite things about the Internet Age, among many favorite things, is the way in which it facilitates access to some incredible paleontology-themed art. The talented artists who illustrated the dinosaurs of my childhood reached their audiences through books or magazines. Now, a quick Google image search, or a brief stint on Twitter, or a browse through deviantART, turns up countless creative and compelling works by artists around the globe. We are living in an age of incredible abundance. Yet, as noted by many paleontologists and paleontological artists, it is still incredibly difficult even for well-known artists to be compensated appropriately for their talents.
