Summary:
Pg. 142-144, 150-157, pls. 2, 3. Term Hudson Highlands complex or High Highlands complex includes entire sequence of crystalline rocks older than Storm King granite. Colony (1921, New York State Mus. Bulls. 249-250) considered Highlands complex synonymous with Highlands crystallines, that is, including Storm King granite. Complex is cut by a variety of pegmatites, and it is not always easy to relate individual ones to specific magmatic interval. Complex includes Grenville metasediments (oldest units of complex), Pochuck diorite phase, and Canada Hill granite phase. Age is Precambrian.
[Type locality not stated.] Report discusses area around Bear Mountain, a prominent summit of Hudson Highlands, about 40 mi north of New York City, southeastern NY. Complex, in this area, is a relatively broad syncline or synclinorium plunging about 40 deg. NE. Storm King granite fills core of syncline.
