Weld County is the third most extensive and the ninth most populous of the 64 counties of the State of Colorado of the United States. The United States Census Bureau estimates that the county population was 236,857 in 2006, a 30.91% increase since U.S. Census 2000.[1] The county seat is Greeley. The Greeley Metropolitan Statistical Area comprises Weld County.

History Edit

On May 30, 1854, the Kansas-Nebraska Act created the Nebraska Territory and the Kansas Territory, divided by the Parallel 40° North (Baseline Road or County Line Road or Weld County Road 2 in the future Weld County). Present-day Weld County, Colorado, lay in the southwestern portion of theNebraska Territory, bordering the Kansas Territory.

Colorado Territory came into existence in 1861, comprising areas formerly part of Nebraska Territory, Kansas Territory, Utah Territory, and New Mexico Territory. Weld County was organized as one of the seventeen original Colorado counties by the First Territorial Legislature on November 1, 1861. Until February 9, 1887, its boundaries included the area now comprising Weld County, Washington County, Logan County, Morgan County, Yuma County, Phillips County, and Sedgwick County.

Weld County is named for Lewis Ledyard Weld, a lawyer and territorial secretary. He died while serving in the Union Army during the Civil War.[1]

In northeastern Weld County, Minuteman III missile silo "N-8"[2], one of the many unmanned silos there, was the target of symbolic vandalism by Catholic peace activists in 2002.[3][4]


Weld County lies within the relatively flat eastern half of Colorado; the northeastern portions of the county contain the extensive Pawnee National Grassland and the Pawnee Buttes, which jut 250 feet above the surrounding terrain. Along the western border some low hills betray the presence of the foothills of the Rocky Mountains further west.

The county is served by two interstate highways: I-25 (US 87) runs through the southwestern corner and I-76 from the south central edge northeastward to the Morgan county border. Other major roads include US 85 and US 34, which intersect near Greeley, and Colorado State Highway 14, which runs through Ault.

According to the U.S. Census Bureau, the county has a total area of 10,416 km² (4,022 sq mi). 10,340 km² (3,992 sq mi) of it is land and 75 km² (29 sq mi) of it (0.72%) is water.

Note: All figures for area and population given above were as of the 2000 census. The area has been reduced since November 15, 2001 with the creation of the new Broomfield County from part of Weld County and parts of Adams, Boulder, and Jefferson counties.
