I'd spooked it from a patch of willow while I was stalking a pair of Canada geese. I hadn't thought I'd see it again-I often bump into deer along Montana riverbottoms-and my only concern was that it didn't put the birds up. But then, as I rounded the bend, I caught sight of it out of the corner of my eye. It didn't see me, and at first I thought the sides of the pool might be too slick for its hooves to gain purchase. For perhaps 10 minutes it swam around, while first my gun arm and then my cramped legs went to pins and needles. Finally the deer stopped at the near edge of the pool, climbed out, and keeping its belly to the ground, slipped back into the thicket without a sound.
