Definitions

Onondaga: eastern Finger Lakes region of west-central New York
limestone: a common sedimentary rock consisting mostly of calcium carbonate, used as a building stone and in the manufacture of lime, carbon dioxide, and cement. See"Limestones and Marbles," from Building Stones and Clay-Products: A Handbook for Architects, by Heinrich Ries, 1912, First Edition
chert: (chert)
a siliceous rock of chalcedonic or opaline silica occurring in limestone
flint: the colloquial name for chert
escarpment: a steep slope or long cliff that results from erosion or faulting and separates two relatively level areas of differing elevations
course: a row of stones
ashlar: cut, rectangular stone used in walls
rubble: irregular, uncut stone used in walls

Characteristics:

There are chunks of black flint (chert) embedded in the gray-colored limestone. Because the chert is much harder than the limestone, limestone is hard to "dress" (trim). The village of Black Rock was named after a large black rock near the Niagara River shoreline. The rock was Onondaga limestone with a large percentage of chert.
Quarriers have to use explosives to separate the rock

Uses:

Was used primarily for foundations.
There are a few houses in the Kensington district in Buffalo that are constructed of limestone.
Today, Onondaga limestone is used primarily for crushed stone in cement aggregate and in riprap (a loose assemblage of broken stones erected in water or on soft ground as a foundation).

Onondaga escarpment:

In Western New York, Onondaga escarpment parallels Route 5 and continues east and it crosses under the Peace Bridge into Ontario and can
be seen along the northern shore of lake Erie. The Onondaga Limestone
underlies the rest of Western New York in the subsurface across NY to the
Hudson River Valley and down into Pennsylvania. It is a very extensive rock
unit.
Extends east to Albany. South of Albany, the escarpment is part of the Heiderbergs Mt.
In South Central New York State, the height of the escarpment varies from 10' to 245'. There are large deposits of gas and oil in this section.

Onondaga escarpment in Buffalo:

Height varies considerably. One high area in Buffalo is at Masten and Best Streets where City Honors School is located. The school building, when it housed Fosdick-Masten H. S., was known as the "The School on the Hill." Another high area is at Kensington and Bailey.
In the Kensington area, as well as in the Delaware Park and in Central Park areas, basements often had to be blasted because the bedrock was so close to the surface, i.e., next to no soil on top of the limestone.
At Robie and Main Sts., the rock is only about one inch below the surface.

Former quarries in Buffalo:

UB (behind Baird Hall). Filled in in the 1960s. UB Main St. campus has many Onondaga limestone buildings, e.g. Hayes Hall.
Bennett Quarry (behind Bennett High School)
On Kensington Expressway at Scajaquada exit, at Delavan entrance, etc.
Next to McCarthy Park in the University Heights area in Buffalo
Vogelsang Quarry at Main and Kensington (at Thruway entrance)
Buffalo Crushed Stone Quarry in Cheektowaga - STILL ACTIVE
