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/)
Sinkholes are all too common of an occurrence in Florida, frequently swallowing cars and houses. The state of Florida has so many sinkholes because it is a karst landscape, composed primarily of limestone bedrock. So what are the odds that a sinkhole appears at Walt Disney World? What if I were to tell you there’s… Continue reading Could a Sinkhole Swallow Walt Disney World?
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
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
The trailer for the new Disney/Pixar movie “The Good Dinosaur” begins by asking the simple question, “What if the asteroid that destroyed the dinosaurs missed?” As a geologist, my immediate answer to the question was, “Well, the dinosaurs still probably would have died out.” Most public knowledge of the End-Cretaceous mass extinction 65 million years ago involves… Continue reading The geology behind Disney/Pixar’s “The Good Dinosaur”
