Remembering Ron Seman: A Legacy of Friendship and Nature

Ron Seman was a beloved advocate for hiking in the Indiana Dunes. On a clear Friday evening, around 25 people gathered to honor him with a walk through some of his favorite trails at Indiana Dunes State Park. This event took place on July 24, 2026, and celebrated Seman’s impact on the community he cherished.

Seman passed away in his sleep at the age of 64 on June 26, leaving behind family and friends who had joined him in exploring the Indiana Dunes State and National Park trails. His widow, Susan Seman, although typically unable to participate in hikes due to health issues, attended the memorial event.

The hike concluded with a gathering on the beach featuring a stunning sunset, where attendees shared memories of Seman’s inspiring presence. Seman was known for hosting Friday evening hikes starting at the State Park’s Nature Center, where he shared the wonders of the dunes, along with insights into its flora and fauna. He was famous for his “10% stories,” which added an entertaining flair to his factual knowledge.

Tiffany Yorek, a regular on Seman’s hikes, expressed the difficulty of his absence but recognized the lasting bonds he forged among the hikers. Ryan Pagell, guiding the memorial hike, remarked that Seman’s spirit would accompany them in future walks.

Barry Tharp recalled his introduction to Seman eight years ago while retracing the same trail. He shared how Seman’s exuberance and expertise made him a unique character. Seman’s contributions extended beyond hiking; he was a “genius-level scientist” and expert on sound technology and computers, balancing these traits with strong Christian faith.

Seman boosted the monarch butterfly population and led the “Monster Dune Challenge” four times a year, covering all 22 miles of trails regardless of the season. Ed Oziminski recalled one of Seman’s final hikes, marked by sweltering weather that drove the hikers into Lake Michigan to cool off.

Marcella Bernat remembered Seman’s influence during her grieving period, when he encouraged her to embrace nature. His presence and insistence brought her solace and recovery. As a gesture of gratitude, Bernat painted a scene of Seman in a canoe, capturing his love for nature.

Connor Zelasko was busy organizing the memorial circle on the beach and had collected 900 signatures for a petition to name a dune after Seman. Although initially declined by Indiana Department of Natural Resources officials, Zelasko remains hopeful.

Seman also contributed to recovery efforts, initiating Thursday night hikes for individuals with alcohol and drug addiction, offering support through nature and community.

Seman’s legacy is deeply felt by many, including Zelasko who recognized the collective sense of loss among friends. Jim Woods reported these reflections for the Post-Tribune.
