History makers of Koochiching County were of many occupations. They were explorers, traders, homesteaders, and lumberjacks. They also were teachers, preachers, merchants, engineers, and builders of industry. Settlers came at the beginning of the 1900s and suffered through isolation, illness, harsh weather, and poverty. They built schools, churches, and good roads. Koochiching County is the second largest county in area next to Saint Louis County. It is also one of the youngest counties in the state having been created in 1906 after it was separated from Itasca County. The name "Koochiching" comes from either the Ojibwe word Gojijiing or Cree Kocicahk (recorded in some documents as "Ouchichiq"), both meaning "at the place of inlets," referring to the neighboring Rainy Lake and River. Reverend J.A. Gilfillan recorded their meaning, "according to some, Neighbor lake, according to others a lake somewhere," possibly referring to the neighbouring Rainy Lake and to Lake Couchiching located in southern Ontario. Early European (French) inhabitants gave the names Lac la Pluie (Rainy Lake) and Riviere ? la Pluie (Rainy River) to the nearby bodies of water because of the mist-like rain present at the falls of Rainy River and then to the settlement that became known as International Falls. About 10,000 years ago almost 90% of Koochiching County was covered by Lake Agassiz. When it receded it left low areas of decayed vegetation (muskeg); as a result, three-quarters of northern Koochiching are underlain with 2 to 50 feet of peat
As reported by the Census Bureau, the county has a total area of 3,154 square miles (8,170 km2), of which 3,104 square miles (8,040 km2)
is land and 50 square miles (130 km2) (1.6%) is water. It is the second-largest county in Minnesota by land area and third-largest by total
area.
Major rivers in the county are Big Fork River, Little Fork River, Rat Root River, Black River, and Rapid River. The highest altitude in the
county is in the Northome area which is 1426 feet above sea level which is about 325 feet higher than Rainy Lake. The land surface is mostly
flat with swampy areas where Lake Agassiz basin was deepest. There are also deposits of peat from 1-1/2 to 50 feet in the low areas which is a
result from vegetation. The general surface of Koochiching County is flat with spots of land broken in places by ledges of precambrian rock.
Bed rock in the area includes ely greenstone and greenstone schists that are said to be among the oldest on the planet. In the northeastern
