San Juan River trip

Next Saturday, 15th of March, I'll be going on a river guide class trip on the San Juan River in south-eastern Utah. It will be a four day journey and hopefully we'll get good mileage down the river during the day so we can pull into our spots early and explore the areas with some small hikes. I'll keep a journal with me as well as a camera to take plenty of pictures. Hopefully I'll get to see some of the petroglyphs there. When I return, I'll add onto this and share some of the stuff our class went through. If there's any thoughts or suggestions on what to take note of in that area, let me know.
