Many people searching the lakeshore for petoskey stones are unaware that it is a fossilized coral. Vast coral reefs grew in the shallow sea covering the middle of this continent long before the glaciers gouged out the basins for our Great Lakes.

I recently visited a remote (and undisclosed) portion of the lakeshore to visit some giant pieces of that ancient reef:

Petoskey stones are abundant along some stretches of the lakeshore




Here's another piece of reef with fossilized corals

And I saw a new (to me) moth on this hike, 
the Leconte's Haploa Moth.




Can you find it here?


How about here?
