As part of the work to install a lift for ADA access and stairs to the second floor, portions of the wood plank floors were removed exposing the soil underneath. State Park Archaeologist, Mark Hylkema, spent two days unearthing artifacts in the dirt floor below the wood floor.
He also exposed the river cobble foundation supporting the historic adobe building. Mark found: shells; bones from bird, deer and fish; ceramic plates; horse tack, metal, old marbles; a shell button; and various parts of glass bottles. The items Mark discovered help with the overall interpretation of the site and a few items may date back to the Castro or Hansen era.
