Hello everyone! I'm heading to St. Louis to observe the Solar Eclipse this week, which is likely to be clouded out. I'm trying to salvage the trip by looking for Trilobite fossils as I have read they can be plentiful in this area. Can anyone share tips on what to look for as far as formations? I think my best bet is to look for rock cuts on the highways in the area. Any help and even general locations to search are much appreciated. Thank you!
