Whatcom County in the Northwest corner of Washington State has a fascinating and elaborate geologic history. A Walk Through Geologic Time is a comprehensive guide to the geologic sculpting of this area's landscape. The book spans the history of the North Cascades and lowland from 1.8 billion years ago to the present and includes information on palm tree fossils, marine fossils, the volcanic and glacial history of Mt. Baker, history of gold and coal mining, and much more.

This book demonstrates that the cause of Ice Ages and smaller climate changes is fluctuation of the sun's magnetic field, which controls the intensity of cosmic rays entering the Earth's atmosphere. Condensation on particles produced by cosmic rays results in formation of clouds that control atmospheric temperatures.
