Around noon, we returned to the car to change clothes and pack for a day of leisure along the banks of the river. After eating the rest of the papaya, and bolillo and avocado tortas, we each took three turns on the swing and plunged into the cool river. I landed badly, and my left ribs still smart days later from landing poorly. We then moved camp to the main section and snorkeled and napped and played games for hours. There were beautiful tropical fish in the water, blue ones and a few sword-tails, bright and colorful and tame. There were small grebe-like ducks diving and swimming underwater. Fresh water springs left a darker grey residue around their geysers, and a thermocline clouded the warmer surface water from the cold springs. It was a paradise! We played Idiot with the cards for a few rounds, read, and napped, until we actually felt a little too much sun. At the end, I wore myself out as I swam and finned a long way upstream, then flew quickly with the current downstream, then labored to return back upstream.
Eating avocado tortas again while they changed and showered, I watched Mexican and Japanese scuba divers enter and exit the river and practice their skills. It seemed so confining to war all that gear just to stay at 20 feet below the surface at the deepest pool at the bend in the river.
