Hawkeye Point (Wikipedia)
Hawkeye Point is the highest natural point in Iowa at 1,670 feet (510 m). It is approximately 4.5 miles (7.2 km) north of Sibley on the eastern side of SR 60 and approximately 3.5 miles (5.6 km) south of the Iowa-Minnesota state border. The high ground lies 100 feet (30 m) due south of an old silo.- Farallon Plate (Wikipedia)
The Farallon Plate was an ancient oceanic plate. It formed one of the three main plates of Panthalassa, alongside the Phoenix Plate and Izanagi Plate, which were connected by a triple junction. The Farallon Plate began subducting under the west coast of the North American Plate—then located in modern Utah—as Pangaea broke apart and after the formation of the Pacific Plate at the centre of the triple junction during the Early Jurassic. It is named for the Farallon Islands, which are located just west of San Francisco, California.
