3. Sinnott Memorial Building (Bldg. #067)
An early Crater Lake service facility, the Sinnott Memorial was Merel Sager’s prototype for the later rustic architecture style he developed for the administrative area. Dedicated in July 1931, the building became a popular park attraction. It is considered to have architectural significance, for it is constructed mostly of rock and located on a precipitous cliff overlooking the lake. Used as a museum, contact station, and viewing point, it has a naturalistic profile that makes it blend into the rim wall. Its large uncoursed stone walls tie in well with the park’s rustic architecture theme. It is recommended that the structure be nominated to the National Register of Historic Places.
