Tree macrofossils dating from the middle to end (about 1000 years, ca. 12 600–11 600 cal years BP) of the Younger Dryas chronozone were found in an organic deposit on the southwest side of the Mohawk River, near its junction with the Hudson River in Cohoes, New York, USA. The fossils included substantial wood fragments, associated plant remains, and pollen, which indicate a forest of white spruce ( Picea glauca ), balsam fir ( Abies balsamea ), and tamarack ( Larix laricina ). The presence of white, rather than black ( P. mariana ) or red ( P. rubens ) spruce in the Younger Dryas was probably due to a riparian-type environment, confirmed by its location and American beaver tooth marks on some of the wood fragments. The clusters of wood radiocarbon dates indicate periodic changes in erosion and deposition at the site. One possible but very short decline (temperature reversal?) may be indicated by tree-ring growth, but in general, the ring widths of the trees and their growth responses suggest variable but slowly improving conditions over time, possibly from warming temperatures, before the end of the Younger Dryas.

Cable Stayed Bridges

<p>The Governor Mario M. Cuomo Bridge has replaced the existing Tappan Zee Bridge in New York. The new bridge was built by Tappan Zee Constructors, LLC. and is owned and operated by the New York State Thruway Authority (NYSTA). The new bridge is a 3.1 mile long crossing of the Hudson River and has an iconic main span structure, consisting of twin cable-stayed bridges, with 1,200’ main spans and 515’ side spans. Each new bridge carries four traffic lanes and the new crossing has been designed to accommodate the future addition of a rail bridge between the roadway decks. Utilizing a probabilistic-based service life design approach, the new bridge has been designed for a minimum 100-year service life before major maintenance for non- replaceable components, such as the foundations, sub-and superstructures. This paper provides the design features of the main span bridge and describes the design solutions, such as the use of fib Bulletin No. 34 to address the Service Life Design of the concrete components to address the durability challenges of this world- class project.</p>

Numerous British fortifications were constructed in the 1750s along Lake Champlain, Lake George, and the Hudson River, all on the eastern edge of the colony of New York. Many of these positions were reoccupied twenty years later during the American Revolution. The author has conducted excavations for nearly thirty years at several of these forts and encampments, seeking to understand the strategies, provisioning, foodways, and building techniques employed by British Regulars and Provincial soldiers as they fought on the American landscape. These sites include Fort William Henry, Fort Edward, Rogers Island, and Fort George, each of which helped to open up the interior of the colony of New York to further settlement.

Glacial Advance

Widespread evidence of an unrecognized late glacial advance across preexisting moraines in western New York is confirmed by 40 14C ages and six new optically stimulated luminescence analyses between the Genesee Valley and the Cattaraugus Creek basin of eastern Lake Erie. The Late Wisconsin chronology is relatively unconstrained by local dating of moraines between Pennsylvania and Lake Ontario. Few published 14C ages record discrete events, unlike evidence in the upper Great Lakes and New England. The new 14C ages from wood in glacial tills along Buttermilk Creek south of Springville, New York, and reevaluation of numerous 14C ages from miscellaneous investigations in the Genesee Valley document a significant glacial advance into Cattaraugus and Livingston Counties between 13,000 and 13,300 cal yr B.P., near the Greenland Interstadial 1b (GI-1b) cooling leading into the transition from the Bölling-Alleröd to the Younger Dryas. The chronology from four widely distributed sites indicates that a Late Wisconsin advance spread till discontinuously over the surface, without significantly modifying the preexisting glacial topography. A short-lived advance by a partially grounded ice shelf best explains the evidence. The advance, ending 43 km south of Rochester and a similar distance south of Buffalo, overlaps the revised chronology for glacial Lake Iroquois, now considered to extend from ca. 14,800–13,000 cal yr B.P. The spread of the radiocarbon ages is similar to the well-known Two Creeks Forest Bed, which equates the event with the Two Rivers advance in Wisconsin.

The region under consideration comprises the coastal portion of New York State east of the Hudson River, including Manhattan Island, Long Island, and southern Westchester County (Map, Fig. 4). The archaeological sites consist of shell middens along the tidal waferways. Although construction work coincident with the expansion of New York City has destroyed many of them and the rest are at least partially disturbed, sufficient material has been obtained for the purpose of this analysis. An attempt is made to establish a chronology of ceramic traits based upon sherds excavated by the writer and his associates as members of the Committee on American Anthropology of the Flushing (New York) Historical Society. Additional data were obtained from a study of collections made by Harrington for the American Museum of Natural History. Consideration of the non-ceramic material is beyond the scope of this paper and must await further study.

First Time

When my wife Joan and I were newly married, we lived in a north Jersey suburb not far from the New York state line. Every weekday morning we drove down the Palisades Interstate Parkway to the George Washington Bridge and crossed the Hudson River to Manhattan, where I taught and Joan was a graduate student. The parkway runs along the Palisades, a magnificent, igneous bluff that flanks the west bank of the Hudson and faces, on the far shore, Yonkers, the Riverdale section of the Bronx, and Manhattan. Wooded parkland extends on both sides of the road for its entire length until just before the approach to the bridge, where many lanes of superhighway converge on the toll booths. We loved the woods along the parkway—they calmed us before our immersion in the chaotic city, and soothed us when we left it at the end of the day. That was before we went on our honeymoon, a three-week hike on the Appalachian Trail (interspersed with some hitchhiking on country roads), from Springer Mountain, Georgia, to the border of the Great Smokies in North Carolina. The forest we walked through was a mixture of tall pines and an incredible variety of native hardwoods—an experience of natural diversity that was overwhelming. Nearly every tree we saw was new to us, yet we could feel the pattern and cohesiveness of the forest as a whole. Rhododendrons formed a closed canopy over our heads, fragmenting the June sunshine into a softly shifting mosaic of dap-pled patches. We stepped on a carpet of rhododendron petals. The trip was over all too quickly. The plane carrying us back de-scended through a dense inversion layer of black smog before touching down on the runway at Newark. Home. We were depressed and silent. The ride from Newark Airport to our house took us on the Palisades Parkway. For the first time, we became aware that the woods along the park way were dominated by thin, ungainly Ailanthus, with their coarse(and, we knew, rank-smelling) foliage, and by other weedy species such as the lanky Paulownia. Suddenly, these exotic species seemed very much out of place.
