see the full deal here. That photo seems to have a big impact in presentations I've done over the past few years. In a field trip a month ago, participants found quite a few nice agates at our first stop, and were somewhat distracted from the geology we wanted to point out. No great loss, though. If they take away the importance of geological materials in construction, I can concede distraction from other rocks.
