What materials did the Iroquois use for their houses?

The Iroquois primarily used natural materials for their houses, known as longhouses. These structures were built using wooden frames made from trees, particularly bark from elm trees, which provided a weather-resistant covering. The interiors were often divided into compartments for different families, and the roofs were typically thatched with additional bark or other vegetation for insulation. This construction method allowed for durability and adaptability to their environment.
