wazzu - there is a little water after you leave the PCT and head towards the summit. Probably 2 miles from the top where the brush gets thick. It's not a strong flow, but should get the job done for you. My son and I carried four litres each and had plenty left. Have a great hike - we might see you there - we are coming up via Deer Springs and looping around to the south and then coming down on the other side for a big circle........................................DUG
