In the mid-to-late 1980s, the Jefferson County Historical Commission embarked on an ambitious Place Names Project to research, document, and catalog known geographic place names in Jefferson County, both contemporary and historic. A large committee was established, and its members scoured USGS quadrangles, history books, and other sources to write descriptions of areas with which they were familiar. The database of almost 2,500 entries was first placed on the county’s website in the 1990s. In 2020 it was transferred to Golden History Museum & Park, City of Golden.

Still a work in progress, you can peruse the descriptions here. We are continually refining the contents. Let us know if you see any errors.

“Golf course construction was authorized in 1968 as a result of a major bond issue passed by North Jeffco District residents.

Indians had planted seeds on hills as a guidepost for their trails. Before the highway department could move the tree, vandals demolished it in 1937. A slab of the tree was taken to the U.S. Forestry Service who determined that the tree sprouted in 1807, was later struck by lightning, and had survived three severe droughts.
