An extraordinary story

Visitors whose curiosity is whetted by this unusual and varied panorama

are not satisfied with only a few questions and answers. They sense that

here for the asking is an extraordinary _geologic_ (_geo_—earth;

_logic_—science) story. With a little direction, many subtle features

become evident—features that otherwise might escape notice. Here, for

example, is a valley with an odd U-shape. There is a sheer face

crisscrossed with light- and dark-colored rocks. On the valley floor is

a tuft of pine trees that seem to be confined to one particular kind of

rock. On the rolling hills is a layer of peculiar white soil—the only

soil in which coyote dens are common. All these are geologically

controlled phenomena. In short, with a bit of initial guidance, the

viewer gains an ability to observe and to understand so much that the

panorama takes on new depth, vividness, and excitement. It changes from

a flat, two-dimensional picture to a colorful multi-dimensional exhibit

of the earth’s history.
