February 8 - Life in Stone: The Long and Extraordinary HIstory of Life in Our Backyard. If you've ever wondered what creatures wandered this area before you got here, or if you just can't keep your hands off of rocks and fossils when you see them, you're a paleontologist at heart. Paleontologists study the ancient life of our planet, and the Four Corners region of the United States has a remarkably long and rich history of life, from some of the most primitive living organisms in the waters of ancient seas, to massive dinosaurs and beyond. From the Grand Canyon to the Uinta Basin, an incredible story of almost 2 billion years of life history unfolds right in our own backyard. Join me on a visual journey throughout the region to meet some of the creatures that swam, slithered, stomped and soared their way through our ancient history. I will bring my extensive collection of fossils to enjoy before and after the show, and I will sign copies of my publications. Offered through Zion Canyon Field Institute.Lecture is at 7:30 PM at the Canyon Community Center in Springdale, UT. Free to the public.

This special 16-day journey takes us down the Alsek River from its beginning almost to the Pacific Ocean. The more leisurely pace will allow for more hiking and exploration (and sleeping in!). This is a rugged trip through the last great North American wilderness, and an incredibly special place. Glaciers, bears, amazing flowers, scenery, and a place so wild that most of it has never seen human footprints.

October 18 through 25 - Nankoweap Canyon Geology and Natural History Backpack. An 8-day geology and archeology exploration of the remarkable Nankoweap region of Marble Canyon. Offered through Grand Canyon Field Institute.

November 1 through 4 - Whitmore Wash Geology and Natural History Class. Come explore a little known region of the western Grand Canyon, famous for its remarkable geology, history and archeology. Whitmore Wash is even more remote than its eastern neighbor, Toroweap, and its geology is no less fascinating. Remnants of massive lava flows, lava dams and perhaps even catastrophic failure of one of these dams surround this beautiful stretch of river and canyon rim. We will hike a very easy stock trail to the river, and spend several days exploring ancient pictographs on the canyon walls, lava flows in spectacular shapes, a beautiful side canyon once blocked by lava, and old cowboy routes into the hills surrounding the area. This is a wonderful place to explore the interplay between geology and human history in a remote and lesser-known reach of Grand Canyon. Offered through Grand Canyon Field Institute.
