Geocache Description:

Camp Sagawau's primary attraction is a dolomite limestone canyon estimated to be 100,000 years old. The only exposed canyon of its kind in Cook County.

The canyon was formed by sand laid down in a huge shallow inland sea more than 425 million years ago and later brought to the surface.

Erosion of water in the stream gradually and slowly created the canyon you see today exposing the limestone walls.

Please note that this is an Illinois Registered Reserve and free hiking is not allowed.


Pull in the gate off of Rt 83 and park in the lot.

For Verification: Measure the depth of the canyon (take a picture of a person of known height and then count how many 'persons' deep the canyon is) and divide by the age of the canyon (ask the tour guide) to see how slowly the canyon is being created.

Not the canyon but an example on how you might measure the depth
