Few People Know These Prehistoric Reefs In Wisconsin Are Hundreds Of Millions Of Years Old
Back during the Silurian Period, about 400 million years ago, this part of the country was covered by a shallow tropical sea. A reef collection formed that’s known as the Racine Formation. The limestone and dolomite bedrock of that was under that sea is what we still see here in southeast Wisconsin. It’s the reason so many quarries were formed here. Those shallow seas were very rich in marine life and the fossils that remain are in display in museums across the state. But you can also get up close and personal with them at the Soldier’s Home Reef near Miller Park in Milwaukee and Schoonmaker Reef in Wauwatosa.
