We saw lots of lightning from distant thunderstorms overnight, but only had one that hit our camp.  On Day 5, the big question was whether we would have turquoise or brown water entering when we reached the junction with the Little Colorado River.  And the answer was brown!  We dodged thunderstorms all day and counted the basketballs in the river from the flash floods that had clearly come through the Little Colorado drainage.  After a nice hike to the hilltop ruins above the Unkar Delta, we ran Unkar Rapid and stopped at Upper Rattlesnake for the night.
