This bridge over the open channel marks the last opportunity for surface water access until Cottonwood Creek or Tylerhorse Creek. This crossing is only 2 miles after Hikertown so you probably have enough water. After crossing the open aqueduct the PCT turns north, and begins to follow the half-buried big rusty pipe of the Los Angeles aqueduct. The water in the closed aqueduct cannot be accessed except for a very bad, undrinkable opening in 20 miles. Luckily people leave gallons of water cached there. To be safe carry extra water and hike during the cool early season and night/early morning to get to Cottonwood Creek.
