More model informationPhotogrammetric model of an outcrop face (~2 m across) exposed at the Lower Falls Recreation Site along the Kancamagus Highway in New Hampshire. The rock is mapped as part of the Jurassic-age Albany Quartz Syenite Porphyry. The outcrop is primarily composed of anorthoclase feldspar and hastingsite amphiboles, with minor amounts of biotite and quartz. Large mafic enclaves occur within the outcrop, generally stretched in an approximately north-south orientation.
