Rocks of the Finger Lakes |

| When geologists study rocks, they usually try to recognize similar kinds of rocks in different places, in order to relate the history of one place to that of another. A layer of relatively homogenous rock that can be recognized across a reasonable distance (for example, 10-20 miles) may be called a formation. Formations are sometimes gathered into groups or subdivided into members. Formations, groups and members are usually given names that relate to the places where they are best exposed. |
