Iowa played its last home football game in town today. An 11AM kickoff, after about 8 inches of wet, heavy snow had ended just hours earlier. This is the overnight field cleanup. The game went on. (Iowa 40, Purdue 20, BTW) And the crews had a bit of fun while playing in the snow ;)
Since Thanksgiving is coming, I thought a cross-section of a Turducken might inspire some deep geo-culinary analysis. If you saw this in a quarry, how would you explain it? Other than taking a fork and knife and carefully excavating ;)
While this a bit too big of a picture to help study, understand, and manage groundwater at any applied level, it does provide interesting perspectives. Simply put, you can't keep fouling the shallow groundwater forever, and you can't keep tapping the deep groundwater forever either. Often, this is becoming a choice.
Iowa Geological Survey staff determined that anomalous conditions below the little city of Decorah, in the NE corner of the state, resulted from a meteor impact ~ 465M yrs ago. The crater contains a shale-fill with great fossils (some with soft-parts preserved), including this big boy. National Geographic had this life-sized statue of the 5-ft long "sea scorpian", made and hauled it to Decorah from Denver for a Homecoming. IGS staff involved with the work went along for the ride. Hoot!
