I have never noticed it before in those shots.  For many years prior to the collapse in 2016 the entire row of cap stones was missing and also most of the course underneath.  With more consistent maintenance the hope is that we won't see a failure of this magnitude again.

Has anyone ever seen photos taken during the original construction of these walls?  If any exist it would be helpful to know.  All help is greatly appreciated!

Justin,

I have never heard nor read of anyone "noticing" the historical damage to the wall, which is why I pointed it out,  I have done so in the past on another thread. see:http://c-sng-discussion-forum.41377.n7.nabble.com/Other-damage-at-Alpine-Tunnel-tp5426p5427.html



This begs the question, and I know Justin is the messenger....why the "want" to rewrite history in repairing the historical damage?, after all the D.L&G and the C&S didn't see the need to.  There certainly wasn't any want to either after the ties were bulldozed off, so why now?  

As shown in the photo's, Mother Nature got stuck in real quick to work on her version.  That snowslide chute is the source of the damage and will be again in the future.

Look at the CHS.J3611 photo I posted above, spare Rails are visible indicating the need for immediate replacement due to rockfalls at any time.  Another photo (inserted below)shows fresh Rockfall at the upgrade end of the Great Rock Wall.  


And no, I've never seen any construction photos either, those I would remember.
