Yeah, I hadn't meant the caption to be a total explanation, only a reminder to me. It was puddled rain water (and therefore water I didn't have to carry for the dogs).
Heading back out for about 3 or 4 miles of hiking today and then we've got to quit for a few days: the snow above 5,000 feet down here needs to melt some with the coming heat before we can hike it. So, after hiking we're off to the Red Rocks for a while, to return here on Thursday or Friday.
