The people who moved into Superior were from diverse ethnic backgrounds. They came from Austria, Slovenia, England, Wales, Scotland, Germany, Italy, Japan and Greece. Other nationalities loved (sic) and worked in various Superior communities contributing much the growth and development of the area. They all shared the hardships and difficulties of relocating to a new nation and living in a remote coal town.
Edith Sunada, whose mother came from Japan to live in Superior states: "my mother thought she's reached the end of the world. Well, you can imagine what Superior looked like in those days. It just had no trees."
Mrs. Sunada cried for days, but eventually adjusted to life in the coal camp. The Sunadas stayed and raised their family in Sweetwater County despite first impressions. They, like other immigrants, found opportunities to gain employment in the remote coal town along Horse Thief Creek.
