In the Beginning: Hiking in Palo Duro Canyon in a place aptly named — Canyon, Texas. Beautiful scenery and not as hot as I would have expected in mid-July!
A lizard lounges in Palo Duro Canyon.
The Teepee Buttes northeast of Pueblo, Colorado, formed by methane seeps when this area was at the bottom of the sea during the Cretaceous.
From the top of Pike’s Peak. We came through hail and are in clouds, so not much view from here. But lightning all around caused people’s hair to stand up.
Garden of the Gods, Colorado Springs, Colorado.
This flat lander is reminded of the importance of abundant oxygen in the atmosphere. As we do some hiking through Garden of the Gods, I run out of stamina quickly, but it is so beautiful. The once-flat sedimentary layers (sandstone and shale) were uplifted by the igneous intrusion that formed Pike’s Peak and, after exposure to the elements over millions of years, have eroded into these lovely formations.
We could actually see Pikes Peak this morning! It’s beautiful and cool as we travel through the mountains toward Twin Lakes and then on to Leadville. We are traveling through terminal, recessional and lateral moraines formed at the end of the Ice Age about 10,000 years ago.
Twin Lakes, Colorado, dammed up by recessional moraines.
Our lunch location, for my chemistry geek friends!

Italy has confirmed they’ve lost their touch.. And so much more! Probably partly stolen by Uruguay who bit the shit out of the players. The usual big guns were all out half the way (the only surprise of WC 2014). 54 more words
Observing at Cerro Tololo in Chile, using the world’s largest digital camera.
Cerro Tololo, bathed in late afternoon sun. You can see the shadow of Cerro Tololo on the distant ridge of mountains.
Cerro Cinchado (cinchado means banded) in the right center, and Cerro Morado on the left. Both these mountains are on the AURA property.
The 0.9m telescope is on the left. This is the telescope we used for the Calan/Tololo photometry of bright supernovae.
The 4m Blanco telescope at sunset.
We still have a small library on Cerro Tololo. I would guess almost no one uses the bound journals since they are all on the NASA ADS server. Many of the books, however, are not. The borrowing cards show the succession of some of the pioneers in the observatories in the Southern Hemisphere.
From my walk today to the western face of Cerro Tololo. The mountain sits on an old lava flow from when Cerro Pachon was a volcano. The lava cooled and formed columnar andesite, like Devil’s Postpile in California.
A barrel cactus growing on the cliff. Cerro Chincado is the banded mountain in the back. The white layer is from the Cretaceous period, and there are fossils in the chalk. At the base of Chincado is an extensive petrified forest.
Bailahuen bushes growing on a cliff. Bailahuen is used in a common herbal tea in Chile. The mountain always has the fragrance of this herb.
Rialto Beach is probably the most unique looking beach that I’ve ever seen. The kind of beach that you’d see in a good movie and that makes you dream about being more adventurous and going to places that look like this place. 158 more words
