With the springtime high-water, exploring side canyons from the boat is an option for the first time. Cannot remember the name of this canyon but Mark liked it while Mark/Rich both paddled 10 Mile Canyon. It's a warm lunch at Bull Hollow Canyon where we take a fruitless hike in search of reported petrified wood. We leisurely paddle on and soon park at mile 83 for a couple of hours of pectoglyph hunting.
