The stratigraphic deposits consist of sandstone, shale, siltstone, evaporites, and limestone representing submergent and emergent landscapes throughout the time frame represented by sedimentary rocks.
Chapter 1 begins with the physiography and geologic overview of the park. Chapter 2 provides a stratigraphic overview of the park's formations. Chapter 3 presents a summary of the Laramide orogeny and its effects on the park and surrounding region. Chpater 4 offers a field tour of the Canyonlands National Park addressing the geographical setting, rocks and landforms, and park observations of the three main divisions: The High Mesas, the Bench-lands, and the Green and Colorado River canyons.
