(You may have missed out on this event this year, but you can certainly read about it at the Waterloo-Cedar Falls Courier website. A link is available here. Also images have been posted at the UNI STEM Facebook page)
The public is invited to the annual Sunday at the Quarry event, hosted by BMC Aggregates LLC. Everyone will have the opportunity to do rock, fossil, and mineral collecting with the Gem and Mineral Society of Black Hawk County, do a geological tour of the quarry provided by UNI Earth and Environmental Science Faculty, and many other programs and displays. There is no charge, and all are welcome.
