The Conference Center Site is located within Lincoln Home National Historic Site, Springfield, Illinois.  In anticipation of new construction onto the rear of the circa 1966 building, Fever River Research conducted archaeological excavations to mitigate the impact of construction on a middle-nineteenth century historical archaeological component present at the site.  The excavations were conducted within what would have been the Mid-Yard activity area of a late 1830s and/or 1840s urban occupation.  Besides a relatively intact (and encapsulated) midden, several shallow features were documented.  These features probably represent the remains of two relatively ephemeral Mid-Yard frame outbuildings (such as summer kitchen and/or wood house).  Additionally, the midden yielded a variety of domestic artifacts once associated with this occupation.  One unusual feature documented during these investigations was a shallow, rectangular pit that was filled with charred corncobs and wood fragments.  This pit may represent a smudge pit (associated with insect control), or document either hide or meat processing activities.
