The Taconic and southern Green mountains form a system of ridges drained by four watersheds in eastern New York and western New England: Lake Champlain and the Housatonic, Hudson, and Connecticut rivers. Ten species of mussels distributed among the Margaritiferidae and Unionidae are recorded, based on museum records and recent collections, from the area. The presence of species representing two regional faunas, the Mississippian and Northern Atlantic Slope, indicates that some western streams of the Taconic Mountain region were connected with both the Atlantic coastal and interior Mississippian drainages during the Late Pleistocene. However, a divide has persisted along the north–south trend of the two mountain chains that has prevented late glacial east–west migration between the Hudson River – Lake Champlain systems in eastern New York and the Connecticut River – Housatonic River systems in western New England.

In the first half of the 19th century scientific philosophers in the United States, such as Emerson and Thoreau, began to pursue the relationship between man and nature. Painters from the Hudson River School discovered the rural spaces to the north of New York and began to celebrate the American landscape in their paintings. In many places at this time garden societies were founded, which generated widespread support for the creation of park enclosures While the first such were cemeteries with the character of parks, housing developments on the peripheries of towns were later set in generous park landscapes. However, the centres of the growing American cities also need green spaces and the so-called «park movement»reached a first high point with New York's Central Park. It was not only an experimental field for modern urban elements, but even today is a force of social cohesion.

Two syenite sills intrude the local Paleozoic strata of eastern New York State and are exposed along the western shore of Lake Champlain. The sills are fine-grained, alkali feldspar syenites and quartz syenites, with phenocrysts of sanidine and albite. The two sills are compositionally distinct, with crossing rare earth element profiles and different incompatible element ratios, which eliminates the possibility of a simple petrogenetic relationship. Zircon extracted from the upper sill yields a U–Pb age of 131.1 ± 1.7 Ma, making the sills the youngest known igneous rocks in New York State. This age is similar to that of the earliest intrusions in the Monteregian Hills of Quebec, >100 km to the north. Sr and Nd radiogenic isotope ratios are also similar to those observed in some of the syenitic rocks of the eastern Monteregian Hills. The Cannon Point syenites have compositions typical of A-type, within-plate granitoids. They exhibit unusually high Ta and Nb concentrations, resulting in distinct trace element signatures that are similar to those of the silicic rocks of the Valles Caldera, a large, rift-related magmatic system. We suggest that the Cannon Point syenites were melts derived primarily by anatexis of old, primitive, lower crustal material in response to Mesozoic rifting and to the intrusion of mantle-derived magmas. The sills indicate that the effects of continental rifting were spatially and temporally extensive, resulting in the reactivation of basement faults in the Lake Champlain Valley hundreds of kilometers west of the active rift boundary, and crustal melting >50 Ma after the initiation of rifting.

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.

This chapter describes the first British invasion of New York via the historic Lake Champlain, Lake George, and Hudson River route in the autumn of 1776. It starts with General Sir Guy Carleton’s successful defense of Canada and repulse of the American attempt to seize Quebec. The increasingly fraught relationship between Carleton and Lord George Germain is also addressed as is the naval arms race between the Americans and the British. This race delayed Carleton’s offensive south on Lake Champlain more than the celebrated Battle of Valcour Island, and he was forced to abandon the offensive after he reached Crown Point, much to the dismay of his second-in-command, Lieutenant General John Burgoyne. This failed first invasion planted the seeds for a new plan created in part by Burgoyne.

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.

This chapter recounts how the author became an evangelist for floating pools by the end of the 1990s. It mentions plans for twenty-five major projects by 1986 that went before the New Jersey Waterfront Commission for approval, from Fort Lee on the north of Hoboken to Bayonne eighteen miles to the south. It also talks about proposals that included parks, marinas, and a continuous waterfront walkway along the west side of the Hudson River. The chapter details how the author won a $25,000 grant from the New York Community Trust to do a feasibility study for the floating project, which in turn brought her to architect Jonathan Kirschenfeld's office to seek his professional help. It describes Kirschenfeld as an earnest man and the very picture of a serious idealist.

Abstract The North East State Foresters Association (NEFA) commissioned a study that resulted in the publication of a report titled, “A Forest Resource Model of the States of New York, Vermont, New Hampshire, and Maine.” In this article we used the integrated NEFA computer simulation framework to go beyond the reported results and further explore the effects on the forest resource in terms of timber harvest, inventory, and price under various market and demand assumptions. Five scenarios were run through the integrated SRTS-ATLAS model to project long-run effects on timber inventory (growing stock) and price. Besides reflecting differing assumptions about demand and supply, these scenarios defined different markets, thus affecting how the wood harvest was allowed to move across the region in response to demand. Regionally, at the end of the 50 yr projection period, cubic-foot growth and harvest were approximately in balance in the Reference Case, the scenario that we felt was most likely. Initial inventory on all timberland was 66.7 billion ft3. By 2050, inventory volume increased 13% to 75.4 billion ft3. Net growth declined over the 50 yr period from 35.3 to 32.1 ft3 ac-1 yr-1, while harvest increased from 26.6 to 31.9 ft3 ac-1 yr-1. Regional real price increased approximately 1.1% yr-1 over the period. Changes in the resource situation in one state affect the situation in the other states. There is a mutual dependence in markets that policy makers need to recognize. The integration of a market module into the NEFA modeling process added the interplay of market forces and improved upon the policy information available from the model.
