Because it was all either eroded away or there wasn't any to be found in New York State. I fixed the fact that they used the wrong form of "there"

In New York State, significant types of bedrock include granite, limestone, and schist, but volcanic rock such as basalt is not commonly found. While there are some isolated occurrences of volcanic activity in New York's geological history, extensive formations of basalt, which are typical in other regions with more volcanic activity, are largely absent. Therefore, basalt can be considered a type of bedrock not typically associated with New York.
The surface bedrock found in New York State at a latitude of 45 degrees north is primarily from the Mesozoic Era, dating back around 200 to 65 million years ago. This bedrock includes formations such as sedimentary rocks, igneous rocks, and metamorphic rocks.

The oldest bedrock in New York State is found in the Adirondack Mountains. This ancient rock, known as the Adirondack Shield, dates back over a billion years and consists primarily of metamorphic and igneous rocks. The region is part of the Canadian Shield and features some of the oldest geological formations in North America.
The processes most likely formed a burial and compaction which the shale bedrock is found near Ithaca, New York.
The most resistant bedrock in New York State is primarily found in the Adirondack Mountains region. This area is characterized by ancient, hard metamorphic rocks, including gneisses and granites, which are more resistant to erosion compared to the softer sedimentary rocks found in other regions of the state. As a result, the Adirondacks feature rugged terrain and prominent peaks, showcasing the durability of its bedrock.
The Adirondack Mountains in New York state contain mostly Precambrian bedrock. This region is known for its ancient rocks that date back over a billion years.
Most of the surface bedrock in New York state was formed during the Paleozoic Era, particularly in the Ordovician and Silurian periods. This era was characterized by significant geological activity, including the formation of marine sediments and the development of various rock types. The bedrock primarily consists of limestone, shale, and sandstone, reflecting the region's ancient oceanic environment.
