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?

Could a Sinkhole Swallow Walt Disney World?
https://youtu.be/nw2xA41RmcA I've done some videos about the real-life geology behind popular attractions at the Disney Parks, but Walt Disney World has some very interesting geology underfoot that may just give you a sinking feeling—sinkholes. The state of Florida is a bit like a slice of Swiss cheese, given the number of sinkholes it has. All… Continue reading Could a Sinkhole Swallow Walt Disney World?
The Wisconsin Dells | An Ice Age and modern water park
Despite its Midwestern location in the heart of Wisconsin, the Wisconsin Dells is today known as the “Waterpark Capital of the World.” However, its rocks—the actual Dells—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 gorges… Continue reading The Wisconsin Dells | An Ice Age and modern water park
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
