https://www.youtube.com/watch?v=1SXaMH8gV6I Earth fissures are long, narrow cracks in the ground that form where the ground is sinking. They can erode very quickly, posing a hazard to nearby infrastructure. In Arizona, land subsidence--the sinking of the earth--is caused by groundwater withdrawal, meaning that earth fissures are a man-made--or anthropogenic--hazard. This video that I made as part… Continue reading Understanding Earth Fissures: A Man-Made Geohazard
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
Not too long ago at a theme park not too far away, Star Wars: Galaxy’s Edge opened at Disneyland—and soon at Walt Disney World—transporting people to Black Spire Outpost on the planet of Batuu. While the tall rock spires of Batuu enhance the other-wordly experience, they take their inspiration from some very real rocks here… Continue reading The Geology of Star Wars: Galaxy’s Edge | Black Spire Outpost, Batuu
Geology, Earth science, and natural history are fun and fascinating! I'm incredibly passionate about the amazing stories the Earth has to tell us! In the blog posts below, you'll find content covering the spectrum of introductory geology to more advanced topics. You can also check out what I'm currently researching and learn more about myself!
Thanks to a variety of weathering and erosive processes, rocks can come in all shapes and sizes. The above rock from the McDowell Mountains near Phoenix, AZ has a peculiar shape similar to that of a mushroom! This rock is an example of a tor--an exposed mass of rock that abruptly rises above the surrounding ground… Continue reading How do you form a mushroom rock?
Disneyland may be one of the happiest places on Earth, but it’s also smack in the middle of California earthquake country. The San Andreas fault runs through nearly the entirety of California and has produced many great earthquakes. The San Andreas fault defines a tectonic boundary between the Pacific Plate and the North American… Continue reading Could an Earthquake Destroy Disneyland?
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
My undergrad advisor has a really interesting article in the New Yorker about the recent earthquakes that have struck Mexico—turns out it’s not the type of faulting you would expect in a subduction zone. The Strange Tectonic Coincidence of Mexico’s September Earthquakes
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?
Ever wondered why the rocks of Sedona are so vibrantly red? I made this video for Arizona State University’s Science Showcase competition, I’d greatly appreciate anyone who can view/share! Plus learning about geology is fun! (Source: https://www.youtube.com/)
