The red line is where the road ran.  Just above it is where the Rialto (Originally the Domado) used to be.  
That's the only new cave-in I found on my trip, and it's a big one.  Notice the water 
is actually colored, while all the surrounding water is clear.   In the foreground is what we used to call 
"The Elephant Hump". It looks much less dangerous filled with water.  The story goes that one of the McGowens 
was riding a bike down about here, and couldn't stop.  Grabbing a tree saved him, but not the bike. 
 It went on down.
