Midwest Nature Quote of the Week: Oct 16

“If one were able to cut through the Loess Hills deep into the earth, the knife would slide easily through the unconsolidated earth nearly to the base of the hills and then would saw with difficulty through several horizontal layers of successively older solid rock.  Eventually, the knife would dig deep enough to hit Precambrian bedrock one billion to two billion years old, a part of the same rock system that forms today’s Rocky Mountains.”

From Cornelia F. Mutel, Fragile Giants: A Natural History of the Loess Hills
