The Contoocook River ( ) is a 71-mile-long (114 km) river in New Hampshire. It flows from Contoocook Lake on the Jaffrey/Rindge border to Penacook (just north of Concord), where it empties into the Merrimack River. It is one of only a few rivers in New Hampshire that flow in a predominantly northward direction. Four covered bridges span the river, one in the town of Henniker, one on the Hancock-Greenfield line, and two in the town of Hopkinton, New Hampshire with one being in the village of Contoocook, and the other in the populated place of West Hopkinton. Residents and tourists have made the Contoocook popular for fishing and whitewater boating. The name Contoocook came from the Pennacook tribe of Native Americans and perhaps means "place of the river near pines". Other variations of the name include the Abenaki meaning "nut trees river" or Natick language meaning "small plantation at the river."The river gives its name to Contoocook, New Hampshire, a census-designated place (CDP) within the town of Hopkinton.

Penacook, originally called "Fisherville", is a village within the city of Concord in Merrimack County, New Hampshire, United States. It lies along Concord's northern border with Boscawen. The name comes from the Pennacook tribe that lived in the area. "Penacook" (Pennycook) was the original name of the plantation incorporated by present-day Concord.Penacook is located along a stretch of the Contoocook River that falls 100 feet (30 m) in slightly over 1 mile (1.6 km), just before joining the Merrimack River. Early hydro-powered industry was attracted to the site, and Penacook grew as a mill town. While dams on the river still generate electricity, most of the 19th- and 20th-century factories, such as Allied Leather, have long since closed.Penacook has its own phone exchange (753), which includes a portion of Boscawen, and its own ZIP Code (03303), shared with Boscawen, Webster, and parts of northern Concord east of the Merrimack River. Most of Penacook is located in the Merrimack Valley School District, though part is in the Concord School District.

The 1638 New Hampshire earthquake struck central New Hampshire on June 1, 1638 (Julian calendar). It was the first major earthquake to strike New England following the start of European colonization. Modern analysis places its epicenter somewhere near what is now central New Hampshire, with an estimated magnitude between 6.0 and 7.0 mbLg. This makes it the largest earthquake on record in New Hampshire and New England, and the second strongest in northeastern North America after the 1663 Charlevoix earthquake.

Lake Merrimack was a glacial lake that formed during the late Pleistocene epoch. After the Laurentide Ice Sheet retreated, glacial ice melt accumulated at the terminal moraine and blocked up the Merrimack River, creating the narrow lake. The lake extended from Manchester to Plymouth, New Hampshire. It is unknown when the lake was drained. Lake Hitchcock is an important part of the geology of New Hampshire. It experienced annual layering of sediments, or varves: silt and sand in the summertime (due to glacial meltwater) and clay in the wintertime (as the lake froze).
