Colorado White Water

We took a short hike along one of the rivers running out of the mountains. There's still lots of snow on the peaks and the river was running fast, high, and incredibly cold.
I couldn't believe it when I saw people in inner tubes doing their best to keep up-right in that wild water. If they'd fallen out hypothermia would have had them in just a few minuets and them they'd get smashed by the rocks. Crazy!
