"Rock hounds, amateur geologists and professionals, will love this series. Great adventure geology!"
—Steve Maynard, Host of 21st Century Stone Age Series
"Well done! Very informative, entertaining and educational. Public awareness of the need for and use of rocks and minerals in our modern society is extremely important. Productions such as the "21st Century Stone Age" will help. This should be in all of the schools."
— Douglas F. Irving, Mining and Geological Consultant, Chapman, Wood and Griswold, Inc.
