With the cooperation of EBMUD, work is continuing on the Rock Wall "Observation Point" constructed along the San Pablo Reservoir in 1935.  With the help of volunteers, we have managed to stabilize most of the site, including the stone stairs that extend down the hill from the wall.  We also are continuing to find surprises as we excavate, such as this concrete structure, purpose unknown, which was apparently added some time after the original wall was constructed.  We eventually will add an interpretive exhibit within the site, serving to make known what is largely ignored by passersby at present.
