Here's how each GeoAdventure happens. I pick a time period for proposed upcoming trips such as "Summer 2015". People contact me to be placed on the "interested parties list" for that trip. When enough people are interested, I contact the group to finalize the trip and date. Once the date is set, I announce the trip and others can register. No previous geologic course work is required.

Travel through Northern Scotland studying fundamental geological concepts and exploring the landscapes and geology of the Scottish Highlands in this unique 12-day field trip.  Scotland boasts spectacular scenery and the most varied geological landscapes of any country of its size in the world.  Edinburgh, the capital of Scotland, is one of the most beautiful cities in Europe and has two volcanoes to boot!  The trip includes multiple night stays in Edinburgh, Inverness, Ullapool, and the Isle of Skye.

Day trips will study fundamental concepts that were important in the development of geology as a science.  Participants gain first-hand experience in relative dating principles and interpreting geologic history.  Four days will be spent exploring the area around Edinburgh and will include Edinburgh’s volcanoes, the area around Dunbar, St. Andrews, and Siccar Point, the location of Hutton’s Unconformity.  The next eight days will explore the Scottish Highlands, including a three-night stay on the enchanting Isle of Skye.  Trips to the north and northwest will study geological processes, structural geology, and landscape development, expanding on the tools learned in Edinburgh.

Explore the remarkable geology along the coast north of San Francisco from Bodega Head to Mendocino in this three-day field trip. Wave-cut platforms, rocky headlands and sea stacks, uplifted terraces, crashing waves, and wide sandy beaches are your outdoor classroom as you discover how the collision of ocean and land has shaped the shore. You explore rocks formed millions of years ago when the ancestral Pacific plate collided with the North American plate, leaving the remarkable and world-famous sequence of marine sedimentary and volcanic rocks called the Franciscan complex. You also investigate the impact of tectonic movements along the San Andreas Fault that are lifting the land and slowly sliding rocks to the west of the fault zone toward Alaska.

The itinerary includes Bodega Head, Mammoth Rock, and Fort Ross on the Sonoma Coast, and Anchor Bay, Bowling Ball Beach, Point Arena, and the Big River on the Mendocino Coast, as well as shorter stops along the way. Participants stay at one or two Irish Beach homes with stunning ocean views of Point Arena. There are numerous short hikes of up to two miles.

Grand Canyon Geology TripGeology of Grand Canyon National Park
June 2011

Click here to view photos from previous Grand Canyon trips

Imagine yourself on a raft on the Colorado River entering into Grand Canyon National Park. This could be you! What better way to raft and explore the Grand Canyon than with a geologist!

The course includes a 6-day oar-powered rafting trip on the Colorado River into Grand Canyon National Park from Lees Ferry to Phantom Ranch. There is also a travel day before and after the trip.

Join me on an exciting journey back through geologic time. The rafting trip travels through progressively older rocks that span the entire Paleozoic Era as Marble Canyon deepens, before reaching the 1.8 billion year-old rocks of the Inner Gorge of the Grand Canyon. This is one-third of the age of the Earth! The geology trip reading assignments are on John Wesley Powell and his explorations of the Grand Canyon and the geologic history of the Grand Canyon and Colorado Plateau. The field trip focuses on geologic processes at work in the canyon, such as weathering, erosion, and mass wasting; depositional environments and sedimentary structures; geologic time and dating; faulting and folding; and igneous and metamorphic rocks. The trip includes a strenuous hike out of the Grand Canyon from Phantom Ranch to the South Rim and numerous daily side canyon hikes.
