A message in a bottle got to hikers downstream. - The family was stuck upstream. Tassajara Creek flows into Willow Creek right before they meet Arroyo Seco River near the Horse Bridge. This sounds exactly like the area where we used to go upstream to from the Horse Bridge. But that much water? Maybe another spot. But we'd go to a waterfall that wasn't so high - maybe ten feet, This NY Post article says the waterfall was forty feet so it's somewhere else if that's true. The one we went to came down into a deep pool. There was a rope on the right side. I never climbed it because there was too much water and I'm not a climber, but Niels Holm did. To get there you walk and swim upcreek half a mile or so and go through a place right before the waterfall that is maybe two yards wide with high walls on both sides. Have to swim there. I've written about that area a few times in the book I'm working on, Tassajara
Stories. Here's a page for some of that and more on the Arroyo Seco.
