Through the archaeological record in Larimer County, CO., an understanding of previous occupants is possible by the application of archaeological site types.
The Spring Gulch site, located approximately five miles north of Livermore, CO., contains information suggesting it was occupied from the Early Archaic through the later part of the Ceramic Stage.
The Archaic levels contained hearths and McKean and Magic Mountain projectile points. Much of the lithic material came from locally available Morrison Formation gray quartzite.
Remains of bison and mule deer were the dominant animal species found in the site, but jack and cottontail rabbit, along with bobcat, pocket gopher, vole, red-tailed hawk, western painted turtle, and freshwater clams were also found.
In one of the hearths evidence of charred goosefoot seed was recovered. In the Early and Middle Ceramic levels of the site most of the recovered tool material was quartzite, and a few obsidian pieces.
Along with ceramic fragments artifacts excavated included ground stone grinding slabs, handstones, and hammerstones.
Not far from this site and Livermore is the Archaic and Ceramic stage Owl Canyon Rockshleter, where small, corner-notched, serrated-blade “Hogback” points were unearthed.
