Once again we put the raft in on the Nevada side of the Colorado River and headed over to the Arizona side. After some searching, we located several possible habitat sites, and I say “possible” because of what we found about half-way through the day. We never found any bottles or Bud Light cans, but we found an “arrow-shaped” design made of rocks. This put in doubt some of the things that we were finding - are they historic or prehistoric? It was still a great trip even though half of what we found may be historic.
