The sense of scale is fantastic. There are a couple of passages where 
I can feel a very thrilling, low Hz resonance-- particularly at the 
beginning and at 2:00 mins, around when the branch falls. If you can 
hear this, do you think this could be some standing waves in the 
canyon?  Every good storm experience must include survival tactics. 
Most folks would have lost the material. Thanks for sharing the 
experience with us, Dan.  Rob D.
