Perched on a pole in low light (evening cloudiness) - I'm thinking white juvenile red-tailed hawk.

Why do we wait to go back somewhere extraordinary, when it's not even that far away? #geology #Canyonlands #hiking  
For someone who can’t get enough of a place, I certainly don’t go there very often. I went maybe thirteen years ago to visit friends living in Moab, Utah, and to watch the Perseid meteor shower on a moonless night in Arches N...

Holy Geyser, Batman! Head out of Reno for a relaxing hot bath under the desert moon after a hard night chasing criminals. Fly Geyser's been spouting for over 50 years since an abandoned geothermal well went awry. Travertine terraces are brilliantly colored by thermophilic microbes, making Fly Geyser one of the more colorful oddities in this normally dry desert.

Staurolite

What otherwise looks like a boring brown mineral, takes on a completely new interest by its crystallographic habit. This is a sample of staurolite, an Aluminum-rich silicate mineral that forms in medium-grade metamorphosed mudstones. It only forms in a fairly narrow temperature range starting ~550 °C, and is one of the important index minerals in metamorphic rocks. It gets its name from the fact that it commonly forms penetration twins, where one crystal appears to be growing through another. The word stauros comes from Greek, meaning cross, so-named for its common appearance due to the twinning phenomenon. Today being Good Friday, a day celebrated by millions of Christians world-wide as the day that Jesus was crucified on a wooden cross, this sample seemed appropriate to share. Most staurolite twins occur at an angle of 60°, like this one, but the 90° cruciform shape also occurs frequently. This spectacular sample, showing an unusual "double" twin on the top left side, is housed at the @fieldmuseum in Chicago.

By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: why slabs of Earth's sinking tectonic plates sometimes stall and thicken 930 ...

We're headed on a blog adventure through the most dangerous kind of plate boundary in the world. To make things clear, the boundary we are exploring is not currently the most dangerous in the world, although it is certainly v...

Sunrise and skiing in our national park. #BryceCanyon #NationalParks
Before the lamb of March turns into the showers of April, there are unanswered questions from my previous post that must be addressed. 1) Will we make it out alive before the amphitheater erodes completely? 2) When exactly d...
