Putz; Cracks in the earth. Here is a the mid continent rift, a rift valley that runs through the great lakes region and into the middle of the U.S. Its a Horst and Graben complex that is filed with debris and Loess and is only visible in Wisconsin Michigan, and Canada. It pretty close to Elk Creek, but is not geologically active.



There is also fault, the Humboldt fault, associated with the Nemaha Ridge (Under the Flint Hills in Kansas.)

https://en.wikipedia.org/wiki/Nemaha_Ridge

he Nemaha Ridge (also called the Nemaha Uplift and the Nemaha Anticline[1]) is located in the Central United States. It is a buried structural zone associated with a granite high in the Pre-Cambrian basement that extends from approximately Omaha, Nebraska to Oklahoma City, Oklahoma. The ridge is associated with the seismically active Humboldt Fault zone. It is also associated with the Proterozoic Midcontinent Rift System, which extends into northern Kansas about fifty miles west of the Nemaha.[2]

Along the Nemaha Ridge is a series of faults referred to as the "Nemaha Fault Zone".[2][3] The long term uplift along the ridge has been attributed to isostatic uplift due to the anomalously thick crust adjacent to the Midcontinent Rift.[4]



Elk Creek is located on or near the northern end of this uplift.
