Classic Rock Tours 3. Grand Canyon Geology, One Hundred and Fifty Years after John Wesley Powell: A Geology Guide for Visiting the South Rim of Grand Canyon National Park

A comprehensive geology guide for the South Rim of Grand Canyon National Park, marking the 150th anniversary of John Wesley Powell’s exploration and the 100th anniversary of the park's establishment. It highlights the significance of deep-time perspectives in geology, tracing human history from the Big Bang to modern times, and emphasizes the canyon as an iconic field laboratory for resolving global geoscience debates. The guide offers three structured activities: a brief overview from Lipan Point, a day hike along the Trail of Time with interactive rock samples, and a full-day descent via Bright Angel Trail to Plateau Point, providing immersive learning experiences. It also chronicles the evolution of Grand Canyon geology mapping over 160 years, showcasing advances in stratigraphy, paleontology, and plate tectonics while advocating for future innovations in science literacy and resource sustainability.
