He will work with Republicans and Democrats to find solutions to the problems facing Wisconsin citizens. He believes that every single person has value, and if we are going to change the direction of our state, we must do it together.The transition from Middle Wisconsinan to Late Wisconsinan is imprecisely dated in eastern Beringia, but floral and faunal data indicate that conditions changed from interstadial to glacial by about 29 kyr BP (Hamilton and Fulton, 1994, Anderson and Lozhkin, 2001). July air temperatures decrease during the LGM seems to have been more ...In central British Columbia, ice flow during the late Wisconsinan Fraser glaciation (ca. 25-10 ka) occurred in three phases. The ice expansion phase occurred during an extended period when glaciers flowed westward to the Pacific Ocean and east-southeastward onto the Nechako Plateau from ice centers in the Skeena, Hazelton, Coast, and Omineca Mountains.

Wisconsinan, that the middle Tahoka clay between the thin dolomite beds was mid-dle Wisconsinan, and that the lower Tahoka was early Wisconsinan (Wendorf, 1961b), in spite of the fact that the bracket-ing 14C ages indicated that the lacustrine clays between the thin dolomite beds were partially late Wisconsinan, as it was under-

present, but age control for all except Late Wisconsinan events is limit-ed to palaeosols and palaeomagnetic data (Whittecar, 1979; Baker et al., 1983; Miller, 2000). Radiocarbon ages are abundant for the Late Wisconsinan deglaciation after 13,000 14 C yr B.P., but they are much less common for earlier Wisconsinan events.Wisconsinan ice reached as far south as Nebraska and Iowa, and glacial deposits from this period provide important clues to the Pleistocene ecology and climate. The Wisconsinan Stage at the end of the Pleistocene Epoch was followed by the Holocene Epoch (11,700 years ago to the present).
