Peteet, D., J. Rayburn, K. Menking, G. Robinson, and B. Stone, 2009: Deglaciation in the southeastern Laurentide sector and the Hudson Valley — 15,000 years of vegetational and climate history. In New York State Geological Association 81st Annual Meeting Field Trip Guidebook. F.W. Vollmer, Ed. New York State Geological Association, pp. 4.1-4.18.

We provide a review of the significant controversy concering the timing of deglaciation in the Hudson and Wallkill Valleys. We outline the differences in methodology and chronology with a circular route through the Hudson and Wallkill valleys. We begin at Lake Mohonk near New Paltz then continue to the "black dirt" region of Wallkill Valley, where John Rayburn has contributed a new GIS model of deglaciation and Guy Robinson will review the history of fossil mammals, including mammoths. We travel southeast to a rare exposure of glaciolacustrine beds on the west side of the Hudson River and on to the Croton Marsh at Croton Point to review the marsh histories of the region.

A recent review of literature relating to the last glacial recession in the Hudson Valley indicates that the timing of deglaciation is very controversial. Some question to consider: 1) Hoe does timing of new lake basal dates at the margin of the ice (Staten Island) compare with sites to the north and inland (i.e., Mohonk)? 2) What is the vegetational history of the region and how does it compare with Deevey's classical southern New England stratigraphy? 3) What is the latest model of the deglaciation of the Wallkill Valley? 4) What have the Hudson marshes added to our understanding of the vegetation and landscape history, particularly in the last few millennia?
