A Greener Sahara: Ancient Oases and Prehistoric Human Habitation in the Modern Desert

via A Greener Sahara: Ancient Oases and Prehistoric Human Habitation in the Modern Desert I was able to interview Dr. Kathleen Nicoll, an Associate Professor at the University of Utah, as part of the Geological Society of American Science Communication Internship. You can learn about some of the research Dr. Nicoll works on in the… Continue reading A Greener Sahara: Ancient Oases and Prehistoric Human Habitation in the Modern Desert

Could an Earthquake Destroy Disneyland?

https://youtu.be/mZhLp-Sa3Ug Ah Disneyland, the Happiest Place on Earth, home of Mickey Mouse, churros, and some shaky rocks. I've previously gone over how Walt Disney World is located in a very sinkhole prone area and that the Epcot World Showcase Lagoon is in part a massive sinkhole, but don't worry the Disneyland Resort has its own… Continue reading Could an Earthquake Destroy Disneyland?

A journey to the center of the Earth | Peridotite xenoliths

You don’t need to go on a Jules Verne journey down to the center of the Earth, sometimes the center of the Earth is brought up to us! These rocks are examples of peridotite xenoliths. A xenolith is a fragment of rock that becomes enveloped by magma without being melted or incorporated into it. In these… Continue reading A journey to the center of the Earth | Peridotite xenoliths

Can you find the unconformity?

An unconformity is an erosional or non-depositional gap in the geologic record. They typically form when an older layer is subject to a period of erosion before the deposition of new sediments.  This road cut near Payson, Arizona shows a pretty cool unconformity. Can you find where it is? Check the jump below to see… Continue reading Can you find the unconformity?

The Wisconsin Dells | An Ice Age and modern water park

Despite its location in the heart of Wisconsin, the Wisconsin Dells is today known as the “Waterpark Capital of the World.” However, it was its rocks—the actual Dells—that first made it a popular Midwest tourist destination back in the 1800s. The Wisconsin Dells—which come from the French word dalles, or narrows—is a 5 mile stretch of… Continue reading The Wisconsin Dells | An Ice Age and modern water park

Speleothems

Imagine that there’s a faucet that’s slowly dripping. If the faucet is left to drip long enough, you’ll notice that it will leave behind deposits from the dissolved minerals in the water. Now, imagine if you left your faucet dripping long enough to create a mineral deposit that was a meter-plus tall. This process is the… Continue reading Speleothems

Pinacate Volcanic Field 

Located in far northwest Sonora, Mexico, the Pinacate volcanic field comprises a 1,500 km2 area of Pleistocene lava flows with over 400 cinder cones and 8 maars. The volcanoes in the Pinacate are monogenetic—meaning they erupt only once and each have a unique magmatic signature. The field today is part of El Pinacate and Gran… Continue reading Pinacate Volcanic Field
