Pack 239 enjoyed a beautiful spring day searching for fossils in the Mazon Creek deposit area near Braidwood Illinois. Our trip was led by Gina Wysocki (fossilnuts@msn.com) who specializes in leading educational field trips and is an expert on Mazon Creek fossils. We started the day viewing a video showing safety tips as well as information about how concretions form around a plant or animal after it died, (some 300 million years ago!) preserving a cast of the original object. Then we were off to find our own specimens. We spent several hours digging in the ravines by the cooling lake and at the end of the day were rewarded for our efforts having collected around 60 concretions. Some of them were not sufficiently cracked to open them without damage, so Gina traded these with the boys for some interesting shrimp, jellyfish and worm samples that she had already opened. Those of us who wanted to try to open them on our own learned how to freeze/thaw the concretions in hopes of expanding small cracks.
