Bridges Over Running Water

I love hiking while the rivers are full, but it seems like the snow comes down from the peaks so quickly.  I hiked a ways up Slate Canyon a couple of times in June, but there was very little water.  I went up Rock Canyon a little ways earlier this week, and still found quite a bit of water coming through there.  I'm interested to keep tabs on it this year and see how long it lasts.  I've also always wondered how many bridges there are up that canyon, but have never bothered to count until this week.
