Announcing Sacred Mounds, a novel of Magical Realism and Historical Fantasy from Jim Metzner, with a foreword by Hutke Fields, principal chief of the Natchez Nation.
Cyclonic hordes of insects, a telepathic despot, body-swapping sex - just a few of the surprises Salvador Samuels encounters when he is swept back to pre-colonial times, walking in the moccasins of a blind Indian - who, in turn, has been transported into Salvador's body in present-day America. Sacred Mounds Book Cover Four hundred years apart, they are bound by a mission to rescue our world, aided by the mysterious presence of the mounds. Thousands of these ancient earthworks once dotted the landscape of North America. We still don't know why they were created. Sacred Mounds suggests they are as important today as when they were made over a thousand years ago. Sacred Mounds weaves the stories of two men, each a stranger in a strange land. With the help of two remarkable women, they must find a way to save our planet and return home.

Clay 4 Window to the PastIf you're searching for a window to our environmental past, you might look no further than the ground beneath our feet especially if there's clay. I'm Jim Metzner and this is the Pulse of the Planet.Schroeder: Clays are records of environmental change. There are several different types of clays that form in the environment. And if we can associate the types of clay in the types of environments we can make our way back into the geologic past, then we can tell whether the environment was wet or dry, and perhaps what types of organisms were living in association with the clays of the time.Paul Schroeder is a professor of geology at the university of Georgia.Schroeder: Geologists use the clays as kind of the key to the past. If you were to look at a clay in the modern forming environment, let's say a desert or in a very wet tropical environment, those clays are distinctly different. And we can work her way back through the geologic record and use those clays as indicators of past environments.This is how geologists reconstruct the climates of the geologic past by looking at the types of clay minerals that are preserved. What surprises us mostly is not so much how wet or how dry or how hot or how cold the earth has been through geologic time. What what surprises geologists is sometimes is how quickly that those properties change on earth. Sometimes the transition from one clay type to the next can be little more abrupt than what we thought. That challenges us to finesse the question what caused that condition to change so quickly. A heads-up that yours truly has written a novel - a work of fiction. If you want more information check out our Facebook page.
