West of the Van Ness corridor, the 1661 Pine street site contains the remnants of a late 19th Century residence. In 1995 Archeo-Tec unearthed a series of redwood floorboards, along with an assemblage of historic domestic refuse and remnants of one or more wall partitions lying atop and adjacent to the redwood flooring. Analysis of these materials, coupled with the findings of historical research, strongly suggest that the structure met its end in the Great San Francisco Earthquake and Fire of April, 1906.

Although the architectural remnants were not as well preserved as originally hoped, the cultural assemblage represents a relatively broad cross-section of the products and furnishings contained within a typical middle class San Francisco household during the late nineteenth century.
