There will be an ESCONI Field Trip to the Larson (Vulcan) Quarry on Barber Greene Road in Sycamore, IL on June 18th 2011, from 9 to 11:30AM. Sign up by sending me an email with the number of people and their names. I will acknowledge by return email. Dave [email protected]
Rules:
1. Must be an ESCONI member.
2. Must be at least 18 years old.
3. Must wear a hard hat and boots.
Be there by 9AM. Park by the metal office on the south side of Barber Greene Rd. We will go through site-specific training before going into the quarry area. We'll need to car-pool into the collecting area since space is limited.
The rock exposed here is Late Ordovician (Maquoketa Group) to Early Silurian (Wilhelmi Fm.). Hammers are usually not needed. Bring a bucket, plastic bags to hold fossils, and something to wrap them in (like TP) if they are delicate.
The most common fossils are brachiopods and bryozoans, but there are also trilobites, crinoids, cystoids, cephalopods and conularids.
I can send directions or a map for anyone who is unfamiliar with the quarry.
