When Grand County was created in 1874 it was carved out of Summit County and contained land to the western border of the state which is now in present day Moffat and Routt counties. In 1877 Routt County was created and Grand County shrunk down to its current western boundary. When valuable minerals were found in North Park, Grand County claimed the area as part of its county, a claim Larimer County also held. It took a decision by the Colorado Supreme Court in 1886 to declare North Park part of Larimer County. So its northern boundary was set. Population in 1996: 9536 people
