This last Sunday, July 29, I rebolted two bolts on "Tilting Terrace" (5.8)
on the Flumes Formation.  On the first pitch, I easily removed the fourth
protection bolt, which consisted of a 1/4" x 1-1/2" threaded split shaft
bolt and a homemade aluminum hanger.  I enlarged and deepened the existing
hole so that I could install a Rawl 6-piece 3/8" x 3-1/2" bolt and a Kong
S.S, hanger painted brown.

I tried to pull the only protection bolt on the second pitch, but the 5/16"
diameter (possibly 1/4") threaded bolt broke at the threads after coming
partially out.  This bolt also had a homemade aluminum hanger.  I pounded
the remaining bolt flush with the rock.  I drilled a new hole in the same
solid block about 4" from the other bolt (the new bolt is in essentially
the same location and orientation as the previous bolt).  I installed a
S.S. Rawl 6-piece 3/8" x 3-1/2" bolt and a Fixe S.S. hanger painted brown.

Bolts Pulled or Broken:  2;  Bolts Replaced or Placed:  2
