The 39th Annual Meeting of the American Society of Reclamation Sciences (ASRS) is June 12-16, 2022, in Duluth, MN. This conference will focus on the research, technical, and regulatory issues associated with the land and water implications of anthropogenic land disturbances. It will provide a forum for the dissemination of information through presentation of research findings, field tours, and open discussion of public policy relating to the applied science of reclamation, rehabilitation, remediation, and restoration of areas disturbed by mining, oil and gas, conventional and alternative energy production, contaminated sites, agriculture, road construction, large-scale commercial development, and other disturbances to land and water resources.

Welcome Reception: Sunday, June 12, 6-8 pm (Included in registration, but please register for planning purposes.)

The Welcome Reception will be held in the Harbor Side Ballroom Foyer, upstairs from the Registration Table for all conference attendees. Reacquaint yourself (in person!) with old friends and meet new ones as you talk with the others at the reception. Appetizers and beverages available.

Haulin’ ASRS: Monday through Thursday, 6:30-7:30 am (Included in registration)

Haulin’ ASRS is an informal running activity during each morning of the conference. It is a low-key running group that meets at 6:30 am. We usually run for 30-50 minutes depending on the conference schedule. The pace is approximately 5-6 mph but is generally based on the ability of the participants. Some people stay with the group for part of the run and then branch off to either go faster, farther or slow down. Running is a wonderful way to meet new people, get some exercise in the morning, and to explore the Lakewalk along Lake Superior! Remember to bring your running shoes to Duluth in June! For those who are feeling competitive, you can look into capping off your conference week by running the renowned Grandma’s Marathon! The Lakewalk is located on the waterfront heading northeast from the Canal Park District, where the DECC is located. People with a desire to join the group for a short run should meet at 6:30 am in the Hampton Inn lobby. From there the group can get onto the Lakewalk and out toward the Gichi-Ode Akiing (Lake Place Park) at the corner of the Lake or toward the lighthouse at the Aerial Lift Bridge. Contact: Dan Guy

Taconite Tour: Sunday, June 12, full day ($65)

Take in Minnesota’s Iron Range mining district at the newly renovated Hibbing Mine View overlooking the Hull Rust Mahoning Mine complex, the “Grand Canyon of the North.” From the unique 360° vantage point, one can see the evolution of reclamation on the Iron Range. One of these sites is United Taconite’s tailings basin, which has been reclaimed to productive use as farmland, wetland, and a hybrid poplar stand. Another is Hibbing Taconite’s 5036 stockpile, an innovative, proactive reclamation site that will become the future pit lake’s littoral zone. In Hibbing, we’ll also stop at the Minnesota Department of Natural Resources mine reclamation research facility, home to field- and pilot-scale reclamation demonstration projects and Minnesota’s exploration drillcore library. We will visit the Redhead Mountain Bike project to view the development of off- road trails on mined land and the Minnesota Museum of Mining.

Duluth Stream Restoration Tour: Wednesday afternoon, June 15, 2 hours ($15)

In 2012, Duluth experienced a two-day, 500-year rainfall event that flooded the creeks running through Duluth’s hillside and resulted in millions of dollars of infrastructure damage. Many of these creeks were subsequently restored and are some of the city’s most beautiful features and are accessible by hiking trails. Guided tour with transportation included.

Peat Mining and Reclamation: Thursday, June 16, full day ($55)

This tour heads south and west out of Duluth to visit active peat mining sites that undergo progressive wetland reclamation. We’ll see the novel harvesting equipment and bagging operations along with reclaimed wetland sites at the Premier Peat and American Peat Technology sites. We’ll also have lunch in Tamarack, where Talon Metals has been actively exploring a high-grade Cu/Ni + PGE deposit. Last, we’ll stop to look at some unique geology and beautiful views at Jay Cooke State Park, located just west of Duluth.


Mine Subsidence Workshop – Wednesday, June 15th
1:30 p.m. – 5:00 p.m. Harbor Side Rooms
The workshop will be broken down into a more in-depth study of land subsidence from the underground mining of coal. It will cover key aspects of mine subsidence, a subject that is not well understood, and embraces several engineering disciplines. The workshop focuses on the causes of mine subsidence and how mine stability relates to the resulting ground movements. Different mining and geologic conditions determine the mode of failure of the mine. The mode of mine failure in turn affects the resulting subsidence movement and consequently the resulting damage. Prediction of subsidence and damage potential and mitigation alternatives are also key aspects of subsidence engineering. Workshop outline consists of causation and risk of subsidence, subsidence movement, and the effect of these movements on structures and pipelines. Also, in the last portion of the workshop, subsidence mitigation alternatives will be discussed. After each section of the workshop, there will be a question-and-answer period. This workshop will be presented in a manner that will be understandable to anyone that would be interested in learning more about mine subsidence engineering. Handouts will be provided,

Instructor Bio: Dr. Gennaro G. Marino has a Ph.D. in Civil Engineering from the University of Illinois. His thesis involved mine subsidence and structural response over room and pillar mines. He presently is a licensed P.E. in 27 states. He has authored numerous articles on subsidence and has received multiple awards for his work, expertise, ethics, and professional development. His work spanning over 40 years includes all aspects of subsidence engineering with government agencies, engineering and architectural firms, surface owners, pipeline, insurance, and mining companies, including planning, mining, and abandonment stages of room and pillar to high extraction workings, and cause and origin investigations.


Vista Waterfront Tour: Monday, June 13th, 10:00-12:00 noon ($35)

Enjoy Duluth’s Waterfront Tour by hopping on the Vista Star! This cruise will take you through the iconic Aerial Lift Bridge and out onto Lake Superior along Duluth’s shores.

See the gilded-age historic Congdon estate in detail. The home of Chester Congdon, general counsel of the Oliver Mining Company developed this 12-acre Lake Superior waterfront estate from 1905-1908. It is now a historical property maintained by the University of Minnesota-Duluth. Chartered transportation to Glensheen is included.

Zephyr Train Tour: Wednesday June 15th, 12:30-2:30 ($40)
