This collection of ten essays honors the retirement of Dan and Phyllis Morse from the Northeast Re­gional Office of the Arkansas Archeological Survey and the University of Arkansas system. A brief recounting of the honorees' professional lives is the subject of a well-written essay by Mary Kwas accompanied by a "selected" bibliography and a short collection of anecdotes. An environmental ac­count of the central Mississippi valley from 16,000 BP to 1000 BP (radiocarbon or calendric is signifi­cant but not stated) by Paul and Hazel Delcourt and the late Roger Saucier follows. Constructed around Saucier's 1994 mapped reconstructions of hydrology/geology, it is fleshed out by paleovegetation derived from eleven sites in the region, four new (but not described here). The Holocene central valley is as well known now as any area south of the glacial border.
