This book explores the landscape evolution of the Paleo-Bell River, a vast ancient river system that once drained much of North America from the Cordilleran mountains to the Atlantic Ocean. The author, James W. Sears, delves into the geological and tectonic history of this river, its impact on the formation of the Grand Canyon, and its eventual destruction by tectonics and glaciation. The study utilizes detrital zircon geochronology and sedimentary analysis to reconstruct the river's history and its environmental significance. Intended for geologists and earth science researchers, the book offers insights into North America's paleo-geography and the processes shaping continental-scale river systems.

"The Belt Basin displays one of the planet's best-exposed and best-preserved sequences of Mesoproterozoic sedimentary and igneous rocks. This volume focuses on research into this province; kindles ideas about this critical era of Earth evolution; and covers aspects of the basin from its paleontology, mineralogy, sedimentology, and stratigraphy to its magmatism, ore deposits, geophysics, and structural geology"-- A collection of papers from the 5th Belt Symposium, Salmon, Idaho, 2013, on the geology of the Belt Basin, or Purcell Basin; the region is the Rocky Mountain Region of the northern United States, extending into Canada.
