As with many western mining towns, the Bingham Canyon area evolved into a collection of diverse neighborhoods, many with pronounced ethnic affiliations. Many Scandinavians lived in the Carr Fork area, while southern and eastern Europeans congregated in Highland Boy, which was in another branch canyon toward the top of the main city. As the mainstreet in the bottom of the canyon grew, Copperfield became the name of the upper section of the main town. Bingham itself attracted British, French, Irish, Puerto Rican, Mexican, and other immigrants and ethnicities. Numerous other small neighborhoods and communities also existed. Most took the name of the mine where they were located. Commercial, Boston Con, and "the Niagara" were the first three communities to be mined away or covered, as the last one was by Galena Gulch waste dumps. Others were the Galena, Old Jordan, and Silver Shield (these three found in Galena Gulch), along with Niagara. Telegraph was in the upper part of the canyon, along with Copperfield, which was threatened when the mining excavating was expanded and a long one-way tunnel was built before 1940 to allow traffic to reach the upper communities. Many names were colorful: Terrace Heights, Dinkeyville, Jap Camp, and Greek camp were sections of Copperfield. The Frisco, Yampa, Phoenix, and Apex were in Carr Fork along with Highland Boy. Further down the canyon were Markham, Freeman, and Frog Town (lower Bingham).
