Up at 6 and emptied packs so we could make it to the river and back with less weight.  Made our way through the wall of foliage and discovered the water we were looking for and thought was dried up.  Went back to camp and got our gear and went back to water to have breakfast.  Since we were already pretty late in the day we decided to spend the day in the shade and in the afternoon hike back up Unkar to the drainage that would lead us to Vishnu.  We spent a relaxing day hydrating, eating and resting.  Around 1:00 we pumped enough water for a dry night and headed back up Unkar.  Found the drainage we needed and finally a small space for camp.  It was difficult as there were trees, scrubs and cacti everywhere.
