First part of August? Plan for some extremely hot weather, bring ALOT of water! Will most likely be very dusty down that way too that time of year, so plan drivetrain maintenance accordingly. Slickrock is fun, but can be challenging. Oh and it is not "slick" so don’t let the name fool you…lol. 😮 Otherwise, look into some of the local shops down there, poison spider is a good one, and they should have lots of info.
