Christmas Tree Rock serves as the marker for both Aragon camp and rapid. Have seen photos of people swimming out to the rock, but the water in April is snow melt. Water bottles froze last night and a Dr. Pepper can exploded on the table. We seem unable to move until the sun came out and didn't launch until noon. Lucy browsing Aragon Rapid. Next bump in the road was Downpour Rapid (II). Ponderosa camp straight ahead at river mile 12.7. Looking back upstream at Dark Canyon Rapid (III) while this is Mine Canyon Rapid (II).
