Last week was a tough week as I tried to stay home as much as possible. On top of the Corona situation, a snow storm dumped 9 inches of heavy wet snow on us. The rain/ snow line was only 30 miles south of us so after looking out on the white landscape for days, I was ready to see green grass again. A decision was made to trek south for the day and enjoy spring again, but with no human interaction. I had wanted to look at a road cut that was discovered on Google-earth this winter and thought this would be a great opportunity. So I was up and on my way early the next morning, leaving the snow just as the sun began to peak above the horizon. The drive through this country is always beautiful. Gently rolling hills with an agricultural community that still is mostly "family farm". The road cut that was explored is shown next, exposing the Stewartville member of the Galena Formation, Ordovician. Road cuts that expose this layer are always nice to explore in the spring. The face is very crumbly and it is obvious in the next picture where the new exposures are hopefully revealing a fresh crop of fossils. Next are some photos showing the fossils hidden in the cliff face. One must be careful not to overlook the sloughed rock at the base of the exposure. Not always are the fossils easily extracted as is shown here!! That is why a bottle of superglue is ALWAYS in my pocket. Almost as important as my rock pick.
