The two main types of glaciers are continental glaciers and alpine glaciers. Continental glaciers are also known as ice sheets because their form and flow are not significantly affected by underlying geographic formations. Alpine glaciers form on mountains and flow down mountain valleys.
Hanover, Pennsylvania. See also: Hanover Township, Pennsylvania (disambiguation) Hanover is a borough in York County, Pennsylvania, 19 miles (31 km) southwest of York and 54 miles (87 km) north-northwest of Baltimore, Maryland and is 5 miles (8.0 km) north of the Mason-Dixon line. The town is situated in a productive agricultural region.
The name Hanover was suggested by Michael Tanner, who was one of the commissioners who laid out York County in 1749 and owned large tracts of land southeast of the town. Tanner's choice of the name came from the fact that he was a native of Hanover, Germany. The town's founders, who wanted to please the German settlers, agreed to the name.
