1934 roof when the building was “restored” and the tile roof
was added. Some of the earlier rafters were left in place and
others were partially removed and new roof trusses installed.
The existing system appears to be in good condition,
although the details of the wall connections, a critical factor,
may not be adequate – additional investigation and analysis
is necessary to determine the adequacy of this part of the roof
system.
A 19 th century ceiling exists above the west part of the
cafeteria located adjacent to the south adobe wall. Several
19 th century buildings are known to have existed in this area
prior to the construction of the current structures attached on
the south side and this ceiling is probably the remains of one
of those structures.
Summary
The condition recording, including fabric investigation
based on a de-construction approach, will continue during the
next site visit, tentatively planned during the spring of 2004.
This will include the drilling of additional holes through the
hard exterior stucco and the removal of selected small
portions of the stucco on the exterior as well as very limited
exposure of the ceiling system in the Mesa Room. Tony
Crosby will also expose more of the top of the adobe wall
where possible. Prior to that, the additional archaeological
investigations will be undertaken.
The continued investigation in the east part of the Mesa
Room will proceed over the next two months. This may
include the excavation of the foundation near the closed
doorway in the south wall, the continuing excavation of the
south wall foundation near the southeast corner, and
completing the excavation and cleaning of the south end of
the east wall. Excavation of the foundation on the exterior
near the northeast corner of the Mesa Room may also occur in
order to collect more information about the foundation
system of both the north wall and the east wall.
The interior deconstruction may proceed with the
removal of a portion of the wall covering and siding on the
interior wall near the southeast corner where the process has
begun with the removal of the gypsum board in this area.
Prior to the actual deconstruction, the project team will
consult and determine the most effective approach.
Because of the difficulty of accessing the attic spaces
above both the adobe rooms, an additional access way will
need to be cut in the ceiling of both rooms, near the west
ends. The new access ways should be constructed similarly to
the existing ones.
Additional historical research should concentrate on the
period between 1885 and ca. 1935, where a gap presently
exists. In addition, the collection of all available historical
photographs should be completed and made available.
