 The 1902 Soil Survey map of the Hickory, North Carolina, area shows Denver having a small grid of streets running along what are now Highway 16 Business and Campground Road.By 1914, the soil survey map of Lincoln County showed only a grid of three short streets running northwest to southeast parallel to what is now Highway 16 Business and one street running parallel to Campground Road (which still exists and was called by locals for many years "Back Street").Apparently, one of the short streets perpendicular to Campground Road ran beside what is now the telephone building on St. James Church Road, and another of these perpendicular streets connected to what is now Campground Road right at the Rock Springs Campground.
