Once we discover the tools past civilizations used to locate resources or mark seasonal changes, we must move to protect them and promote their significance to Indigenous history.
For thousands of years, indigenous people of North America constructed monuments of earth and stone. Each structure had a meaning and a purpose. Some honored those who died. Some were used to mark and prepare for seasonal changes. Some pointed the way toward valued resources. Some were landmarks. Some mapped the destinations to be reached from a trail crossing.
Measuring the Earth
Measuring the Earth is a set of lessons designed to show how astronomy, geography, and geometry are connected to the construction and use of earthwork monuments across North America.
Astronomy
Watching the movement of the sun, moon, stars, and planets from a set location was a way to understand a place and time.
These images of sunrise show how observing the sky from a specific location can provide a wealth of information. Similar patterns are related to certain mound and stone monuments in North America. (Images obtained from opensource software available from Stellarium.org using background for Grossmugl Mound, Austria.)
Geometry
Geometry shouldn’t be limited to lessons on a flat piece of paper. Understanding geometry in 3-dimensions starts with a basic understanding of how most people perceive the world with two eyes.
Geography
Indigenous oral traditions recount the origin of the continent of North America with Turtle placing mud on its back. In English, the name for North America is Turtle Island.
