For the person interested in how NPS maintains their historical
architecture, you may want to contact the local regional office in San
Francisco who maintain Yosemite Park. For Crater Lake Lodge, contact Mr.
Loren Huffman, Historical Architect, Pacific Northwest Regional Office,
Cultural Resources Division, National Park Service, in Seattle [they have
a new address I'm not sure of] phone number:(206) 220-4000
good luck.
