An Oddity: A large rock has impressive (large) root complex on top of it. How these roots survived after the massive carving & pounding of this canyon is interesting. Keep in mind the distance - it is large (rock and roots). (see image in post 2444 by Repeal The 17th to see the relative size of closer workers).
I suspect the heavy rock trapped these roots underneath it following hillside vegetation erosion near the upper spillway break. For the roots to remain after the hydraulic forces + the rock debris pounding on the roots is impressive. note: I do not believe that this is a mass of rebar.
This image shows a good view of intact "Load Transfer Bars" left in the Sidewall Slab. This evidence confirms the missing design detail -of these load transfer bars- in the original construction blueprints. Discussion links 1 & 2 on FRposts below.
The size/length of these "intact load bars" answers another question on the broken junction of the sidewall slab and remaining main slab that is pulling away from the upper main spillway. An "illusion" was created by concrete remaining around the hidden load transfer bars. The remaining concrete was left attached to the left sidewall slab but this remaining concrete is not part of the sidewall slab but is part of the main slab that fractured away. Thus it created an "illusion" that the joint between the two slabs was a "beveled" type. (see third FRpost link below, circled section in post image).
These "Load Transfer Bars" confirm the "bonding force torque" link re: the downslope sliding of the failing Upper West Sidewall and the adjacent spillway slab (sliding & slight rotation). Hopefully the new drilling & subsurface repair work will have stabilized this section from further movement when the spillway is put back into use.
