Flash flood is a greater worry to me than getting lost or being avalanched. Recall April 2008 when 7 of 12 “canyoneers”, most students, were killed in a flash flood in New Zealand.

I lost my video of a mountain trail that was very old and very tracherous. It was built by Indians a long time ago on sheer face cliffs and a lot of ti is crumbling and falling away. Don’t remeber the name of it but it was supposed to lead up to a site of worship.
Can anyone help me?
you did not mention were you were hiking but I think the Ledge Trail from yosemite valley to glacier point would sure be a candidate it was closed in the 50-60 becuse of fatalities the old rule we used was up ledge down 4 mile never down ledge
