Thought I'd compare photos to see if it's dropping - it is! The photos are taken from slightly different angles, so the non flush surfaces give a false impression, but check out the upper right of the bottom block - in the first pictures it's in line with the dark scratch on the main face, in the second pic it's below it!

He he, that's scary. Can you estimate what time it'll drop!

Eek! I posed my daughter for a "comedy" photo beneath the guillotine a couple of weeks back. Good parenting eh!

I think it'll be a while before it goes, since it's only dropped a couple of inches in 3 years, and you never know if may just be getting more wedged, but would be interested if one day it parts company!

Had a walk into California earlier today.......This block has now parted company with the rest of the cliff!!!

Really? It was moving glacially slowly, I didn't think it would drop for years...
