So it's been more than a year since I last updated this space. The last time was for a show. And this time? Poster for our next show! A new show by Raven Amos, myself, and Zach Miller! (To be honest, I update often enough elsewhere, so it seems sort of redundant to come here every time. But here I am.) And so the details: First Friday is on the 3rd of October 2014, and we'll be there.

Soils at Imaggeo: fall into litter

Antonio Jordán University of Seville, Spain Description Wet forest soil surface after a rainfall simulation experiment in Los Alcornocales Natural Park, southern Spain. When pores are saturated with water, rainfall does not infiltrate, but a dense litter layer may inhibit runoff for some time.

Oregon's Mount Hood Rumbles. 

Volcano Science And News Blog [2014-09-08 16:45:00]  recommend  recommend this post  (43 visits) info

Oregon's Mount Hood, one of the famed Cascades volcanoes, has produced a few shallow earthquakes below the summit. What this means is uncertain, but it is probably typical of the volcano. Mt Hood last erupted in 1866 although there are some unconfirmed reports of eruptions in the very early 1900's. A magnitude 2.6 quake occurred below the summit at 3.7km depth, and a much shallower 2.1 one at 0.9km depth. There are currently no reports on these quakes at CVO or USGS.At this time it is unlikely [...]

There comes a time toward the end of the expedition where things can spin on a dime from having lots of time to not having enough. After the second bit change we were bringing up loads of rocks- sometimes recovering 70 percent. We were making progress toward drilling a column of rocks that would overlap with the rocks in the previous site to discover how this subduction zone was layered. read

Science is about asking questions, as much as it is about finding answers. Most of the time spent by scientists doing research is used to constrain and clarify what exactly is unknown – what does not yet form part of the consensus among the scientific community. Researchers all over the globe are working tirelessly to answer the

So much has happened in the field of human evolution in the last few years! Two end member theories have been popular for some time. The Out Of Africa theory says that modern humans originated in Africa around hundred thousand years ago and then spread all over the world replacing local populations of humans from older migrations. On the other hand the multiregional scenario said that

I posted in an earlier blog entry about some Trilobite fossils I had from Bolivia. At the time I could not tell what the genera was of them because there were no labels. Well I found the specimen below in a box with some older E-bay purchases and it has a label calling it Metacryphaeus sp. (which makes my job that much eaiser!). It is preserved in a neat pose that looks like it was buried in the mud, with just it's head exposed, while it awaited prey.This specimens come from the Belen formation [...]
