    Lily Cache Creek by John Griffis

    The creek was mostly frozen oven with ice except in the middle. I stupidly stepped down from the bank, fell, then slid on my butt to get to open water, sampling while sitting in ice cold water. Then I scooted back. Next time--just skipping it if it is like this.

    Mostly ice covered except along shorelines where water velocity kept ice from forming.
