Join geologists and authors Paul Link and Shawn Willsey as they describe and present their completely revised second edition of "Roadside Geology of Idaho." This new guidebook uses vivid maps, pictures, and text to describe the geology and landscapes along all of Idaho’s highways and freeways. One of several side trips describes the geology of Trail Creek road into the Pioneer Mountains which will be featured in the presentation. A book signing will follow, and books will be available for sale from Chapter One. Register to attend or learn how to join us virtually at
