Palm Fossil from Arizona

During my visit to the Gallery of Natural History at the Arizona Historical Society Museum at Papago Park (1300 N. College Ave, Tempe Arizona 85281) I saw fossil specimen (AHS-NH#14891) from Yavapai County, Arizona USA. It is a polished palm tree...

Accidental Remediation | 21 October, 2014
I used to talk on the phone while driving... quite often, actually, although not for very long for any given conversation. I've stopped entirely, for two reasons: in the last couple of years, more and more jurisdictions have made cell phone use illegal while driving; and when I broke down and got a smartphone and started receiving work e-mails, I had to have an "unlock" password that makes the phone a giant pain to dial with.

Hot Topic | 21 October, 2014
In my post at The Daily Blog this week I take inspiration from the great Ian Dury, and reflect on the disconnect between political ambition and the state of the climate system as it continues to warm. It will be my last post at TDB for a while - fo...

Geo 730: October 21, Day 659: Full Punchbowl

Outside the Interzone | 21 October, 2014
I've mentioned Devils Punchbowl quite a number of times, but shown a photo of it only once before in this series. That one was at a low-ish tide, though clearly not unusually low. At negative tides, the interior is easily accessible on foot, and it looks as if in that photo, there's water in the right portal, where one would enter. But here we see it at high-ish tide, and in relatively calm conditions. Even calm, you wouldn't want to get stuck in here; the water is extremely cold. I don't clearly recall the weather on this day, but it was cool and quite gusty. I know I didn't enjoy being exposed to the wind, and I had to hold my cap down frequently. It would not be fun, in fact, quite hazardous, to get soaked in this water, then if you made it to shore safely, trying to trudge out in the chilly breeze. Hypothermia is a serious concern year-round on the Pacific Northwest coast.

QGIS user group – presentation

scottishsnow | 21 October, 2014
I spoke today at the second Scottish QGIS user group meeting. It was a diverse gaggle of practitioners including academics, council, quango and no doubt many more. Some really interesting talks went on, a few of which I took photos of (see below). Unfortunately I was so absorbed in the best two talks (Mag Low and Heikki Versanto) that I didn't take any shots! They both demonstrated the excellent threejs plugin which allows you to create 3D fly throughs in html very quickly, Anita Graser has a good example.

Climate, Water and Hay Aligned in Kittitas Valley

Climate, available irrigation water and good soils align in the Kittitas Valley to make this central Washington valley an attractive area for growing livestock feed. Some history might play a role as well.

Seven Hills of Seattle

Stories in Stone | 21 October, 2014
"Seattle's hills have been its pride and they have been its problem; they have given the city distinction and they have stood in the way of progress," wrote Sophie Frye Bass in her 1947 memoir, When Seattle Was a Village. As the granddaughter of city founder Arthur Denny, Bass was in a good position to witness the early history of Seattle and her book is often credited with popularizing the sentimental notion that Seattle was built on seven hills, just like ancient Rome.

I’m on TV!!

Geosphere | 21 October, 2014
About a year ago I was asked to appear as a guest on a kids television show about rocks and minerals called Finding Stuff Out. I was asked to come an talk about rocks, minerals, geology in general and how I got interested in geology. The show is for 8-10 year olds and it is truly fantastic! It has a really interesting format where kids actually ask questions and the host, Harrison, answers them with the help of experts (me), goes to places to find the answers or does experiments. In the end the show concludes with an answer to the question that started it all. In the case of my episode it was about diamonds.

Slow Worms at Wormsloe

Every time I visit the Georgia coast, traces that have been there all along make themselves apparent to me for the first time. One would think these personal discoveries would stop happening after more than fifteen years (on and off) of going to that coast and studying its traces, especially after writing a 700-page book about them (Life Traces of the Georgia Coast). Nevertheless, they happen, and when they do, these insights underscore the importance of doing regular field work in the same places. However familiar it might seem, there's always something different you missed previously while there. So before each trip to the Georgia coast, I make sure to become wide-eyed and expectant, rather than jaded and bored.

Why don't people use viz rooms?

Agile Geoscience | 21 October, 2014
Matteo Niccoli asked me why I thought the use of immersive viz rooms had declined. Certainly, most big companies were building them in about 1998 to 2002, but it's rare to see them today. My stock answer was always "Linux workstations", but of course there's more to it than that.
