I hiked Morris Peak, Mt. Jenkins, and Owens Peak on Day 1 of a 3-day backpacking trip along the PCT in the Owens Peak Wilderness. I started with 3 liters, but by the time I climbed all 3 peaks and made it to the next water source I was pretty dehydrated. It was warmer than I expected, making this a pretty hard day. Camped in upper Cow Canyon near a small seasonal stream.
