While New York City is certainly best known for its towering skyscrapers and classy historic districts, its earliest monuments of stone are just that: stone. The geologic landscape of the city was formed between 20,000 and 18,000 years ago with the movement of the Wisconsin Ice Sheet down from Canada. The rock and debris deposited from the ice sheet, as well as the valleys it deepened, bedrock it smoothed and glacial grooves it left, formed the landscape of the city that began to grow in the colonial era. In some cases the rocks have been moved or crumbled in the name of urban development. But some of this geologic history can still be seen within the urban environment. This collection highlights some of the more well-known geologic features.

364 Van Duzer Street CLIENT: Robert M. Hazard ARCHITECT: Unknown DATE: 1835 STYLE: Greek Revival This frame house, built in modified Greek Revival style, is one of the last remaining examples in the area. The most striking feature of this house is the stately tetrastyle portico with its Doric columns rising two stories to an entablature below an overhanging spring-eave. The use of a spring-eave on a Greek Revival house, rather than a triangular gable, is unusual and is more characteristic of the so-called Dutch Colonial style.
