These trips are custom-designed for the geology enthusiast. I pick an existing trip or develop a new one and propose a time frame for offering that trip such as "September 2015". People contact me to be placed on the interested parties list for that trip. When enough people are interested, I finalize the trip dates and costs and announce the trip to the interested parties list and collect deposits. I then announce the trip to the general public to fill any remaining spaces. No previous geologic course work is required.

Scotland Geology TripScotland Rocks! Geology Field Trip
June 2-13, 2015

Photos from the Scotland trip

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, whiskey-tasting, castles and more!  Trips to the north and northwest will study geological processes, structural geology, and landscape development, expanding on the tools learned in Edinburgh.

Scotland Geology TripIceland GeoAdventure
August 2016

An 14-day adventure to one of the world's geologically most fascinating places with Doris Sloan, me, and a fabulous local guide, Elisabet Brand, who knows everyone and seemingly everything Iceland! 

Iceland's great variety of volcanic features is due to a hot spot and a tectonic plate boundary where the North American and Eurasian plates spread apart.  In addition, it has fjords, glaciers, waterfalls, puffins, fulmars and many other birds, beautiful small horses, and wonderful people.  We will take you around the island to see many of its special places and we will walk across the spreading plate boundary in three different parts of Iceland.

This trip is going to fill early, so contact me for more information.

September 19-21, 2014 - $400 - Registration open & filling up fast.

Photos from previous North Coast trips

Explore the remarkable geology along the coast north of San Francisco from Bodega Head to Mendocino in this three-day field trip, spending nights in cliff-top custom homes. 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.

Yosemite/Eastern Sierra Geology Field TripYosemite/Eastern Sierra Geology Field Trip
September 2015

The Yosemite and Eastern Sierra trip is a 5-day exploration of the Yosemite Valley and the Eastern Sierra from Bridgeport to Bishop, including Devil's Postpile, Bodie, Mono Lake, and the Long Valley Caldera.  The beauty and spectacular geology and landscapes of the Yosemite Valley are awe inspiring.  The Mammoth area is the most active volcanic area in the continental U.S. in the last million years and has some impressive glacial features.  We will even have the chance to soak in several hot springs!  Camping and lodging options are planned in both the Yosemite Valley and Mammoth area.

Grand Canyon Geology TripGeology of Grand Canyon National Park
September 2016

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. Contact Tom for details on the Grand Canyon Geology Field Trip and to be added to the Interested Parties list.

Private Half-Day or Full-Day Geology Field Trips
Along the Marin and Sonoma Coast from the Marin Headlands and Point Reyes to Salt Point State Park I would love to design a short trip for your family or group. Price negotiable based on group size.

Come experience the geological playground that is Death Valley National Park in this unique week-long field trip. Travel through geologic time and view the limestones and volcanic rocks of Titus Canyon. Explore a ghost town at Rhyolite. Hike through the colorful sediments of Golden Canyon. Ponder the mystery of Racetrack Playa. Hunt for fossils at a Paleozoic limestone reef.

This is a 6-day geology field trip that begins and ends in Bishop, California. We all meet in Bishop on Saturday evening and return the following Friday evening.
