The forest coats of downy white; provide with tender care. Sleep 'til the time of spring returns; and gentle grace awakens.
Those patches that you can see drifting down the Rock River are a skin of freshly formed ice, and they contain bits of sediment from the river bottom. If I remember my high school chemistry correctly (no guarantees), water reaches its maximum density at about 2 deg C (36 deg F), and becomes about 10% less dense when it undergoes the state transition to become ice. It freezes at 0 C (32 F), and the extra 2 C is lost due to the energy consumed by the state transition. Therefore, that skin of ice contains unlovely yellow-green traces of whatever was on the bottom of the river when it froze. That's my theory. Anyone care to correct me?
Winter arrives in Wisconsin. It's about ten days early if you go by the calendar. So much for nice days and pretty autumn colors...
