4. Crotana Park

Crotona Park is on the south side of the Cross Bronx Expressway at Exit 3. The park is in a Bronx neighborhood that has witnessed significant urban development in recent years. Numerous exposures of schist and gneiss of Cambrian Manhattan Formation are present throughout the park, many of which bear glacial polish, striations, and groves (Figure 21). Crotona Avenue extends northward from the Park to Fordham Road. Just east of Crotona Avenue, Fordham Road is the boundary between the New York Botanical Gardens and the Bronx Zoological Park.
