On a sunny day the Tetons seem ageless and constant. Stand by a river during the spring run-off and listen to the clack as one stone tumbles over another. Hike a mountain trail in the summer and see the tops of sub-alpine fir broken by an avalanche the previous winter. Watch the clouds build along the crest as you race a thunderstorm down from Paintbrush Divide on a summer afternoon. Witness the re-growth of grasses, wildflowers, and sapling lodgepole pines following a fire. Soon you begin to realize that the park is constantly changing.
Some of these forces are incredibly powerful and their impact is easily and readily observed. Some, however, work on a time-scale that is imperceptible, but change the landscape in no less dramatic a fashion. Some changes are the result of natural processes and some are the result of human actions. It is certain, however, that change is a constant in the Teton Range.

Did You Know?
Did you know that the black stripe, or dike, on the face of Mount Moran is 150 feet wide and extends six or seven miles westward? The black dike was once molten magma that squeezed into a crack when the rocks were deep underground, and has since been lifted skyward by movement on the Teton fault.
