The 1924 two-story building of rough-cut thinly coursed local sandstone includes a gymnasium wing extending from the rear of the rectangular classroom portion. 

The two-story brick building was constructed in 1911 to house the Meeker operations of J.W. Hugus & Co.  Founded by J.W. Hugus in 1877, the company operated numerous general and dry goods stores in southern Wyoming and western Colorado.

The 1897 I.O.O.F. Lodge – Valentine Lodge No. 47 provided an important social venue, not only to the I.O.O.F. Lodge members with various assistance, but also to the community and various organizations.  Local engineer Herman Pfeiffer designed the architecturally significant Late 19th and Early 20th Century Revival style building.  The Lodge used the upper floor while the lower floor was leased to merchants, a government office and for school classes at one time.

Constructed in 1896, this two-story brick building reflects the characteristics of commercial structures built in small western towns during the late 19th and early 20th centuries.

The M.J. Patterson Contracting Company of Denver completed this pin-connected, six-panel steel Pratt pony truss in 1901.

The 1892 Coal Creek School is a good example of a one-room rural schoolhouse that has also served as a community gathering space and polling place for several decades.  The coal shed/privy and horse shed remain on the property. 

The site is important for its use by Utes well into the late 19th century during their annual fall and winter gathering of pinyon nuts in the surrounding area.

In September of 1879, Ute warriors skirmished here with troops under the command of Major T.T. Thornburgh as the troops entered the Ute Reservation on an expedition from Fort Steele, Wyoming to the White River Agency in northwestern Colorado. 

The 1938 building served as an annex to the adjacent high school and provided space for classes in agriculture, a blacksmith shop for manual training, and a sound-proof music room for the band and orchestra.  While successfully serving these purposes, the building went on to provide other educational opportunities. 

The park is associated with several Great Depression era federal relief programs.  Constructed between 1933 and 1938 under the Civil Works Administration (CWA), the Federal Emergency Relief Administration (FERA) and the Works Progress Administration (WPA), creation of the park provided a source of employment in Lamar during much of the Depression.  Willow Creek Park was Colorado’s first CWA project and the first planned park in Lamar, providing a location for active and passive recreation activities.
