In the mid-to late 1990's, also one weekend in 20I0, a friend & I were at Crystal Grove. Did find some nice individual crystals, rough with crystal pockets, and took home a bucket of sandy sub-soil where it can be sifted thru a window-screen sifter and a tea strainer sifter over paper 3-sided open 'box' to remove the sand & find micros from .05mm to 1/4" herkimers. Sometimes other things are found in sifted soil.
