These little life forms bring back so many memories of childhood, collecting them and watching them sprout legs and lose their tails as they metamorphose into the frogs and peepers that fill the swamps and edge waters of the temperate forests. These were in the Rock River. The water is flowing swiftly so they hang at the edges where the water is slow and warm. You can notice all the little green pebbles strewn in the photo.
There is a nickel mine upstream and that metals presence can add the green color to many rocks/minerals that combine with nickel. Around 5, 5:30 to the group of 3 polliwogs is a piece of chrysoprase; green colored quartz. I only noticed it when I inserted the photo. Then there is a clear green piece of something at the 10 o'clock position to the 3 tadpoles. It looks like fluorite. I've heard there is some in the area. Many more tiny green pieces are present. I may have to bring a mask to the river to get a close up view of what is in the fines of the river.
