" Exploring Iceland's Geological Wonders: From a Regional Perspective to a Hiking Expedition "

Speakers: Don Barrie & William Buckley

For the May Meeting, we return to the Catalina Room at Marina Village, for the speaking duo of Don Barrie & Will Buckley to detail their overland trek of Iceland and the Mid-Atlantic Ridge. This will be more than a mere travelogue as they will take you on their cross-country hiking expedition for a close up look at the still-erupting tectonic plate boundary and discuss Iceland's unique geology in detail. Please join us at the Walawender Bar, and enjoy this exciting presentation.

Don Barrie, San Diego Mesa College

speaker Iceland is a large oceanic island developed at the intersection of two regional submarine structures, including the Mid-Atlantic Ridge and the Greenland-Iceland-Faeroes Ridge. The origin and evolution of Iceland since early Miocene time have largely been controlled by the localization of subaerial ridge segments atop the Iceland plume, followed by ridge migrations and jumps. Plate divergence occurs along the North, East, and West Volcanic Zones; oblique divergence occurs along the Reykjanes Volcanic Belt - the site of current eruptive activity near Mt. Fagradalsfjall and the town of Grindavik. Ridge-ridge transforms include the South Iceland Seismic Zone and the Tjörnes Fracture Zone. With its ~30 active volcanic systems, Iceland hosts a diverse array of volcanic landforms, including shield volcanoes, scoria/spatter cones, stratovolcanoes, calderas, cone/crater rows, rootless cones, and subglacial volcanic landforms. Icecap margins are currently experiencing rapid post-glacial isostatic rebound at rates of up to several cm/yr.

Don Barrie is a geology professor (partially retired) at San Diego Mesa College. His passion is to make geoscience accessible to diverse audiences. Prior to joining the Mesa College faculty fulltime in 2004, he taught geology, physical geography, oceanography, and natural disasters at Mesa, Cuyamaca, Grossmont, and MiraCosta colleges and at San Diego State University. As a professional geologist (PG) and a certified engineering geologist (CEG), he has over 14 years of professional experience managing geotechnical and environmental investigations in the U.S. and abroad. Before becoming an educator, he worked as a geologist with AMEC Earth & Environmental where he managed field projects in southern California, Arizona, Hawaii, and Guam. He holds a B.S. in geology from Cal Poly Humboldt and an M.S. in geology from the New Mexico Institute of Mining and Technology. He currently serves as a board member at the Anza-Borrego Desert Natural History Association and regularly leads geology-themed trips to Iceland and New Zealand.

William Buckley, Geocon

speaker Geologic and geomorphic characteristics of Iceland were observed during a ~580 km (~360 mi) self-supported hiking expedition spanning from the southernmost to the northernmost points of the island by linking together a combination of hiking trails, road networks, and cross-country navigation. The route closely followed the tectonic plate boundary between the North American and Eurasian Plates, where the two plates are spreading at a rate of approximately 2 cm/yr. Starting in southern Iceland at Black Sand Beach in Vík, the route navigated across remnants of past eruptions which most notably included the 2010 volcanic events at Eyjafjallajökull. These volcanic events occurred over a span of several months and caused significant disruption to air travel across the western portion of Europe. The route then traversed near Mýrdalsjökull, a distinctive glacier that caps one of Iceland's largest active volcanoes known as Katla. Katla is considered to be one of Iceland's most hazardous volcanoes due to its frequent eruptions and potential for large-scale events, with its most recent major eruption having occurred in 1918. The route then led into Iceland's interior - a barren volcanic desert, also known as The Highlands, where water is typically scarce, vegetation is sparse, and is characterized by extensive lava fields, calderas, and geothermal activity. One of the notable features observed in The Highlands included a volcanic complex of nested calderas referred to as Askja, which last erupted in 1961. The route finally traverses through northern Iceland, a region characterized by mountains, fjords, kettle lakes, and coastal plains, and ultimately led to Iceland's northernmost point, the Hraunhafnartangi Lighthouse. Despite the challenges posed by severe weather conditions during this expedition, the journey ultimately confirms the unrivaled rewards gained from navigating across the captivating landscapes in Iceland, where interaction between geologic and geomorphic processes, both past and present, have shaped the island's topography and creates an exceptional environment for exploration and study.

Will Buckley is a dedicated geologist currently employed at Geocon, Inc. With over nine years of experience in the geotechnical industry, he specializes in conducting geological and geotechnical investigations across a diverse range of projects. His particular interests involve hazard studies, where risks are evaluated and assessed for proposed and existing developments in areas prone to faults and landslides. He holds a B.S. degree in Geology from California State University, San Bernardino, and an M.S. degree in Geological Sciences from San Diego State University. Prior to his professional development as a geologist in the geotechnical industry, he cultivated a unique passion for understanding geological processes through undertaking backpacking expeditions in various climate systems. This passion has taken him across much of the western U.S. and beyond, providing firsthand experience with different geological and geomorphic processes.
