1. Plowed fields: Arrowheads are often uncovered when farmers plow their fields. Look for areas with high ground and good drainage, as these were often Native American camping grounds.
2. Riverbanks: The banks of rivers and streams were commonly used by Native Americans as travel routes and hunting grounds. Look for areas where the water has eroded the soil, exposing artifacts.
3. Wooded areas: Native Americans often camped in wooded areas, especially near water sources. Look for areas with a mix of trees and open ground, as well as near rock outcrops or caves.
4. Construction sites: Construction sites can sometimes uncover Native American artifacts, especially when they are located in areas that were previously inhabited by Native Americans.
5. Public parks and nature preserves: Many public parks and nature preserves in Central Illinois have areas where Native American artifacts have been found. These areas are often marked and protected, so be sure to follow the rules and regulations when searching for arrowheads.
It is important to note that it is illegal to collect artifacts from public lands without permission. Always seek permission from the landowner or relevant authorities before searching for arrowheads. Additionally, be respectful of the land and leave no trace of your presence.
