I was on a short hike today and I walked past a small area where rainwater often collects and due to the recent low temps, it was ice. So I began to wonder if the ice was drinkable. Would it be safe to just pop in a small piece? Aside from the obvious dangers of lowering your core body temp, would there be any bacteria present in the ice to be worried about? Perhaps the safe bet would just be to throw some chunks in a cup and boil it over the fire?
