    Harms Woods/Glenview Woods by Mac Austin

    Took water from the southeast side of the bridge because I was unable to get down to the river and past the ice on the north side of the bridge where I normally take the water from. The edge of the river and much of the river bank were slick and slippery with ice. Had to break through the ice at river's edge to get to the water. Deep freeze in past week; warming slowly over the past few days. High thin clouds with small patch of clear.
