Outcrops of gneiss on Eau Claire River at Big Falls County Park. The best exposure of almandine in rocks of the park (a large porphyroblast in gneiss) was illegally removed by a collector a few days after he was shown the outcrop on a field trip led by UW-Eau Claire geology faculty. This deprived any future geology groups of the ability to study its occurrence in place. Such geological vandalism reflects poorly on the collecting community, and deserves to be discouraged and condemned when discovered.
