Have you ever traveled up Mitchell Canyon Road and looked at the quarry?  As docents, we often try to answer these questions from visitors:  What is happening up there? Where is that rock going?  What kind of rock is this and what does it tell us about the origin of Mount Diablo?  How long will that quarry be in existence and what happens when they are done?  All of these questions and more will be answered by representatives from CEMEX, the operator of the quarry and a supporter of MDIA.
