INTRODUCTION

Valley Forge National Park represents an important part of our nation’s history as it honors the memory of the thousands of American soldiers that died here during America's War for Independence. The park also illustrates a significant part of the region’s geologic history, as it contains rocks that formed as far back as 525 million years ago. Over the course of hundreds of millions of years, the Earth’s internal and surface forces have worked to produce a resource of practical value and scenic beauty. The lush, fertile hills have supported agriculture for most of our nation’s history. Topographic features furnished protection from attack for General George Washington and his troops during the long winter of 1777-78. Rocks within the park have been the source of industrial raw materials and scientific specimens.   By understanding the geologic history of Valley Forge, we may understand the significance of some of the park’s most interesting features and landforms.
