Old Faithful

Old Faithful about to blow sky high. My photo.
OLD FAITHFUL.

There really isn't an option of talking about Wyoming without talking about Yellowstone and Old Faithful, especially because most people think Yellowstone is in Montana. Yeah, like 5 minutes of it (it's a sore spot for Wyomingites).

Members of the Washburn-Langford-Doane Expedition spotted Old Faithful on September 18, 1870 (of course, Native Americans in the area had long been aware of Old Faithful).







Nathaniel P. Langford wrote an account of the expedition:

In another part of Langford's diary, he described the complete lack of understanding by white folks of the delicate ecosystem of geysers. Old Faithful was sometimes used as a laundry in the early days:

Along WY-28 and WY-131

One of my favorite roads is WY-28, and one of my favorite places is Sinks Canyon, just off WY-28 near Lander. The middle fork of the Popo Agie River(*Puh - Po Shuh) "sinks" into a limestone cavern and then reappears on the other side of the ridge. It can take water up to two hours to make the journey through the cavern. It's a incredible place.

Not for those without good walking shoes or agility, however. There's a bit of scrambling up and down the enormous rocks that were left there from the last Ice Age. The ice scraping down the canyon exposed the deeply buried Madison Limestone Formation and then billions of gallons of water from the melting glaciers flowed into the soft rock, creating the underground passages.

The Sinks are still slowly eroding from current of the river, but haven't changed much over the past hundred years. Historic photos from the early 20th century show the cavern to be almost identical to how it looks today. Which is kinda cool, geological speaking. :)

Get a sandwich at The Breadboard in town while you're at it. I highly recommend the Hot Pastrami.








Red Canyon: remember, red usually mean IRON!

I went to Peru!

I do want to talk about our travels to other places. Hope that's Ok. :)

Our travels mix geology and anthropology so seamlessly, it's hard to talk about them separately. But to shorten each post, I'll give it a whirl:

Peru is smack in the middle of the Andes. Because of this geography, one side is Amazon Rainforest, and the western side is mostly desert (Google "rainshadow"). I was on the western side for my recent trip, so the similarities between where I visited and southwest Wyoming were striking.

The rocks of Peru are amazing. Andesite, one of the fundamental types of igneous rocks (made from magma and lava), was first understood by studying the rocks of the Andes. The geological of the Andes is similar to the Cascades in Washington State, but different because of the availability of different elements and minerals in the crust there.

Here are a few photos of both landscape and rocks I found during my time in Lima, Cusco, and at Machu Pichu. I took LOTS of pictures, more than I can possibly share.

And yes, I love taking pictures of rocks.






PS - The food is AMAZING. The original home of the potato!
