I Spy Erosion: Demonstrating a Tool to Document Visual Indicators of Coastal Erosion

This is an opportunity to get down to the Lake Superior waterfront, build coastal observation skills, and learn a new tool.

Join the Coastal Hazards of Superior (CHAOS) Community of Practice (CoP), a group focusing on the Minnesota and Wisconsin coasts of western Lake Superior, for a field trip to Lake Superior's south shore.

Learn about:

  • Spotting signs of erosion
  • Estimating shoreline erosion rates
  • Understanding bluff slope stability

This field trip will start at Schafer Beach public access point to view a range of eroding shoreline conditions in bluff and beach environments. 

Presenters will:

  • Demonstrate a site assessment tool that can be used to document signs of shoreline erosion
  • Show how to collect the data and measurements needed to determine the risk of erosion and bluff instability to coastal buildings, structures, and habitats.
