Farming communities tend not have occupational histories. Cascade is no different. A vague occupational history can be found on the local rootsweb site. It boils down to this. Most of the community were farmers or involved in support industries, such as the local flour mill. A list can be found here. Like many farming communities, Cascade gained industry in the 20th century. Factories eventually began to pay a role in daily life, although farms remained important.
Unfortunately, without hearing from the individual workers, you miss a lot. Cascade probably has an amazing story. Does anyone know where I can find it?
