About Duluth

We are excited to bring the GSA 2020 North-Central Section Annual Meeting up north to Duluth, Minnesota, USA. Perched on the western tip of Lake Superior, Duluth offers unparalleled beauty and natural amenities. The meeting will be held at the Duluth Entertainment Convention Center, within walking distance of the thriving Canal Park district and downtown Duluth. Field trip opportunities let you explore a range of geologic history: step back into the Precambrian to the Duluth complex or Mesabi Iron Range, trek up to the Gunflint Trail to see ejecta from the Sudbury impact, explore Quaternary history recorded in proglacial lake deposits, investigate modern processes ranging from landslides to peatlands to environmental remediation, or learn more about the depths of Lake Superior onboard the Research Vessel Blue Heron. Come north for a geologic adventure!


Duluth is home to the Duluth International Airport (DLH), serviced by United, Delta, and American Airlines. The Duluth Transit Authority (DTA) connects the airport to the downtown transit station via bus route 8 on weekdays. On weekends, bus route 5 services the airport. Several hotels, including the Holiday Inn Downtown, offer an airport shuttle. Duluth is also serviced by taxis, Uber, and Lyft. The Minneapolis/St. Paul International Airport (MSP) is a 2.5 – 3 hour drive from Duluth. Ground transportation between Duluth and MSP is available through the Groome Transportation shuttle service, Landline airport bus, and the Jefferson Lines bus.
