Hi Chris,

The plan is to reconstruct the wall as it was originally built and to historical completion.  Stone masons who specialize in "the old ways" have been consulted and will be providing the formal bids.  Below the failed portion the wall is also bulging out.  This will all be taken down and properly reconstructed as it was originally.

In addition there will likely be a rock scaling effort above the wall to try to minimize damage for the foreseeable future.  Also the lower portion of the Williams Pass Road below the grade will be restored in order to provide access for the repair.  It is actually pretty lucky that this road passes just below the wall otherwise construction would be even more complicated!

Thank you very much for the photos showing the historic damage.  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!
