I, too have been thinking about that culvert, Bernina. I haven't been through there for years but I know there are a few bridges on the trail, but I think they all go over dry land (maybe to allow for water spill-off from the mountains?) There's even one creepy one that you have to take turns to cross because it's only one car width wide that I hated going over. Good thing that restaurant in Tortilla Flats had good chili

I don't remember paying a toll, but there might have been. That culvert seems quick and easy to me. Adrienne was about 100 lbs, I believe, that's a lot of weight to carry somewhere, or even to lift out of a trunk or back seat. As far as the condition of her remains, I don't know anything about decomposition or decay (not sure I have the stomach for all of it, frankly) but is it possible that she was wrapped in something, such as a blanket, shower curtain, tarp or something like that that may not only keep animals from scavenging, but delay decomposition? Could that explain why there were "legs" for the property owner to find? If that was the case and it came off while she was moving down the wash, it could be literally anywhere...maybe even further down stream then they found her body, right?
