Black Hills Intro	Aug 20th, 2007 1:29:24 am - Subscribe
So the Black Hills? It's true, they really do look black from a distance. I spent 10 days in South Dakota studying the geology of the region with 15 other people including the professor. Other geologic sties we visited that are related to the Black Hills are The Badlands, Devil's Tower and Bear Butte. The Black Hills are a unique and diverse geologic region that exhibit many geologic features. These features include uplifted sedimentary rock groups, metamorphic layers, granite/pegmatite intrusions including the the Harney Peak (Mt. Rushmore) lacolith. There are also faults, cenozoic intrusions (Devil's Tower and Bear Butte) as well as some of the largest caves in the United States. Other features we studied were sills, dikes, unconformities and erosion. So that's the more technical info. I'm not sure who is going to be reading these blogs but I plan on making them more accessible and detailed than that last paragraph. As I write my field report I will update the blog and illustrate with photography. So far I plan on writing about The Badlands, Harney Peak and Mount Rushmore, Jewel Cave, Devil's Tower and the Needles Highway. I may add an entry on the Mammoth Site in Hot Springs as well. I will update my first article in a couple days, I look forward to developing some readers and testing out my ability to teach through articles. I plan on being a teacher and I am going to be an Earth Science Tutor at my college this year.
