While on the way to the North Cleaver route on Adams on June 15, 2019, we came across a 1.5-liter blue Nalgene. It was sitting on a rock at the intersection of Killen Creek Trail and PCT. Judging by the stickers, it probably belongs to someone from Seattle, or at least from the state of Washington. Pictures attached. If you know who it belongs to, please contact me by private message.
