A bird’s-eye view drawn in 1882 shows Black Hawk in Gilpin County, Colorado, with Gregory Gulch near the top center, Chase Gulch to its right, and both gulches feeding into North Clear Creek as it winds across the town. Mills, foundries, homes, and businesses occupied the limited level ground and stone-buttressed terraces on the steep hillsides, while the Colorado Central Railroad followed North Clear Creek and continued to Central City on a four-mile spur with two switchbacks. By 1882 the Gilpin Tram had not yet been built, and the hillsides were already bare because trees had been used to fuel mill furnaces and construct buildings. Surviving structures include commercial buildings such as the ca. 1860s Rohling Block, the 1875 Jenkins-McKay Hardware Building, and the mid-1880s Gilpin Hotel, as well as a portion of the Polar Star Mine in Chase Gulch, residential houses including the Carpenter Gothic-style Lace House on Main Street, and public buildings including the 1870 Schoolhouse, the 1863 Presbyterian Church, and the 1877 City Hall. The mills, foundries, and related businesses shown in the lithograph no longer exist, and much of the land along North Clear Creek that they once occupied is now used by Black Hawk’s casinos and their lodging and dining facilities. The Colorado Central Railroad made its last run to Black Hawk in 1941, and the Gilpin Tram ended its nearly forty-year life in 1917; the tracks, depots, and trestles of both railways are gone. Black Hawk’s population has declined from about 2,000 in the late 1880s to 140, the church above the commercial center beside the public schoolhouse has been converted to city offices, and the schoolhouse now serves as the police station.
