County of coos

new hampshire

History & Founding

Located in the northeastern corner of New Hampshire, this county is a vast expanse of wilderness and small, close-knit communities. Established in 1850 from parts of Grafton and Carroll counties, its name honors Silas Coos, a frontiersman and Indian trader who played a significant role in the region’s early settlement. Coos, known for his knowledge of the land and interactions with the Abenaki people, helped pave the way for European expansion. Prior to the county's formal establishment, the area was a frontier zone, attracting hardy settlers seeking land and opportunity. The county’s development was intrinsically linked to the lumber industry, which shaped its towns and provided the economic backbone for many years. An interesting anecdote from its early history recounts a brief, localized "Coos War" in the mid-1800s, a series of disputes between rival lumber companies vying for control of prime timber resources – a testament to the importance of the industry and the rough-and-tumble nature of the frontier.

Geography & Landscape

The county encompasses 1,801 square miles, making it the largest in New Hampshire by area. Its geography is dominated by the White Mountain National Forest, showcasing a rugged terrain of steep slopes, dense forests, and pristine waterways. The Connecticut River forms its eastern border, while numerous rivers and streams, including the Ammonoosuc and Passaconaway, carve their way through the landscape. Lakes like Lake Francis and Crystal Lake provide recreational opportunities and add to the scenic beauty. The climate is characterized by cold, snowy winters and mild, humid summers. The towering peaks of the White Mountains, including Mounts Washington, Jefferson, and Adams, are visible from various points within the county, offering breathtaking views. The landscape is a haven for wildlife, including moose, bear, deer, and a variety of bird species.

Economy & Communities

The county is comprised of twenty towns, each with its own unique character. Lancaster serves as the county seat, and other significant towns include Berlin, Littleton, and Colebrook. The economy is primarily driven by tourism, agriculture, and small businesses. Historically, logging and paper mills were major employers, although their influence has diminished over time. Today, outdoor recreation, including hiking, fishing, hunting, and snowmobiling, attracts visitors and supports local businesses. Agriculture remains important, with dairy farming and maple syrup production being notable aspects of the rural economy. While small-scale manufacturing exists, the overall character of the area is rural and sparsely populated, with a strong sense of community and a slower pace of life. Notable employers include local schools, healthcare facilities, and tourism-related businesses.
