The Taconic Mountains are a 150-mile-long sub-range of the Appalachian Mountains lying on the eastern border of New York State and adjacent New England. The range, which played a role in the history of geological science, is separated from the Berkshires and Green Mountains to the east by a series of valleys, principally those of the Housatonic River, Battenkill River and Otter Creek. The Taconics' highest point is Mount Equinox in Vermont at 3,840 feet (1,170 m); among many other summits are Dorset Mountain, Mount Greylock and Mount Everett.

The river flows west from a rugged portion of the central Sierra Nevada into the Central Valley and ultimately the Sacramento–San Joaquin River Delta, where it empties into the San Joaquin River-Stockton Deepwater Shipping Channel. Together with its main tributary, the Cosumnes River, the Mokelumne drains 2,143 square miles (5,550 km2) in parts of five California counties. Measured to its farthest source at the head of the North Fork, the river stretches for 157 miles (253 km).

The Archaeological Conservancy is a 501(c)(3) non-profit organization that acquires and preserves archaeological sites in the United States. Whereas nearly every other nation protects all archaeological sites within its borders as part of its national patrimony, in the United States archaeological resources on private land are the private property of the landowner. As a result, archaeological sites in the United States are subject to destruction by urban development and sprawl, mechanized agricultural and land-leveling, and commercial looting to fuel the antiquities trade. By the 1970s the extent of archaeological site loss was increasing recognized as a crisis for the scientific study of the nation's past.

White-nose syndrome (WNS) is a fungal disease in North American bats which has resulted in the dramatic decrease of the bat population in the United States and Canada, reportedly killing millions as of 2018. The condition is named for a distinctive fungal growth around the muzzles and on the wings of hibernating bats. It was first identified from a February 2006 photo taken in a cave located in Schoharie County, New York. The syndrome has rapidly spread since then. In early 2018, it was identified in 33 U.S. states and seven Canadian provinces; plus the fungus, albeit sans syndrome, had been found in three additional states. Most cases are in the eastern half of both countries, but in March 2016, it was confirmed in a little brown bat in Washington state. In 2019, evidence of the fungus was detected in California for the first time, although no affected bats were found.
Black Pond Wildlife Management Area is a 526-acre (213 ha) New York State Wildlife Management Area (WMA) that lies on the eastern shore of Lake Ontario, and at the northern limit of an unusual region of sandy barrier beaches and lagoons.

Glacial Lake Albany was a prehistoric North American proglacial lake that formed during the end of the Wisconsinan glaciation. It existed between 15,000 and 12,600 years ago and was created when meltwater from a retreating glacier, along with water from rivers such as the Iromohawk, became ice dammed in the Hudson Valley. Organic materials in Lake Albany deposits have been carbon dated to approximately 11,700 years ago. The lake spanned approximately 160 miles (260 km) from present-day Poughkeepsie to Glens Falls.
Joppenbergh Mountain is a nearly 500-foot (152 m) mountain in Rosendale Village, a hamlet in the town of Rosendale, in Ulster County, New York. The mountain is composed of a carbonate bedrock overlain by glacially deposited material. It was named after Rosendale's founder, Jacob Rutsen, and mined throughout the late 19th century for dolomite that was used in the manufacture of natural cement. Extensive mining caused a large cave-in on December 19, 1899, that destroyed equipment and collapsed shafts within Joppenbergh. Though it was feared that several workers had been killed, the collapse happened while all the miners were outside, eating lunch. Since the collapse, the mountain has experienced shaking and periodic rockfalls.
North Woods and North Meadow are two interconnected features in the northern section of Central Park, New York City, close to the neighborhoods of the Upper West Side and Harlem in Manhattan.
