In the frontier days on the Great Plains, most settlers either lived in a log cabin or a soddy, which was made of grass turf.
A soddy, or sod house, was an alternative shelter when wood or stone was scarce. Settlers who lived in sturdier homes might still have built soddies to house their animals. Using thick strips of turf, dense with deep-rooted prairie grass, people would pile stacks into sturdy walls. Doors and windows were fitted into the soddy walls, and a sod roof added on top. These grass houses were cheap and quick to build, but vulnerable to rain.
