Looking back down at the river we were dropped off at... It's very flat and fairly easy to hike along the riverbed, but dusty and sandy, and you just have to accept that your boots will get wet. There are a lot of incoming streams to cross, and even where they braid, it's not so likely that you can get across without having to step through water over your boot. We didn't run into anything deeper than mid-calf, and most of it was much shallower, but a couple of inches of fast running water will go quite high on your leg (and into your boot) when you step into it and block the flow.
In the list of silly things we did to try and keep from getting our boots wet, attempting to toss our packs across had to be the most ridiculous. We were faced with a stream that was only a couple of feet across -- narrow enough to jump without a pack, but not with a pack. Deb was eyeing it like she might try to jump, so I suggesting tossing the pack over. It's just a couple of feet, right? As if one can easily toss a backpack with a week's worth of gear and food in it. She tried, and held on to the pack a moment too long, and the pack carried her right into the stream with it. She pulls it out on the other side, and for some reason, I thought I would be able to toss my pack better than she did. So I proceeded to do exactly the same thing she did, and ended up in the stream, laughing at myself. Not just wet boots, but wet pants.
