Archeological maps of Chicago, as well as oral stories from Native communities, tell us that Chicago was home to both permanent village sites and more seasonal camps for centuries before the arrival of Europeans. Though the Thompson Center is more often recognized for its unique post-modernist design and rotunda, it is also the site of one of these many seasonal camps.
These camps were used for "seasonal rounds," annual patterns of coming to a particular place at a particular time. Indigenous people developed these cycles based on the growth cycles of plants and the migrations of animals. Many Indigenous people lived this way before colonization because it was a sustainable way of life. These seasons followed a predictable pattern for planting, hunting, fishing, and harvesting. Moving this way allowed for communities to regularly renew their connections to each other. In Chicago, some examples of seasonal activities include: Collecting sap from maple trees to make sugar and syrup and harvesting plants like ramps in the Spring; fishing and
tending to vegetables like corn, beans, and squash in the Summer; hunting migrating birds like ducks and geese and harvesting wild rice in marshes and small lakes in the Fall, and hunting muskrats, otters, and beavers in marshes, as well as deer in forested areas in the Winter.
Because of how close this camp is to the river, we can guess it may have been a spring camp used for harvesting ramps, or a summer fishing camp. Ramps, which are a type of wild onion, are where Chicago gets its name. Several Native place names for Chicago have meanings related to this plant, including Zhegagoynak (Potawatomi) “place of wild onions” and Šikaakonki (Myaamia and Illinois) "wild leek place." Others have names related to strong smells, such as Gųųšge honąk(Ho-Chunk) "skunk run" and Sekākoh (Menominee) "place of skunks." If you've ever walked into a patch of ramps you will understand the reason these words are related - the smell of these spring onions is known to be overwhelming.
