Ron Seman, renowned trailmaster of the Indiana Dunes, would have cherished the clear skies and perfect weather that marked the Friday night memorial hike in his honor. About 25 people joined the walk on trails 9 and 10 at Indiana Dunes State Park, paths Seman favored for their panoramic views of Lake Michigan.
The hike occurred on July 24, 2026, as a tribute to Seman, who passed away in his sleep at age 64 on June 26. Hikers descended segments of Trail 9, pausing at a scenic dune ridge. His widow, Susan Seman, though usually unable to join due to health issues, participated alongside friends and admirers.
After the hike, attendees gathered on the beach, bathed in the vibrant hues of sunset, to share memories of Seman. Known for his extensive knowledge of the area’s natural environment, Seman often added a humorous twist he called a “10% story.”
Chesterton resident Tiffany Yorek, 42, a regular on Seman’s hikes, expressed the difficulty of his absence, but acknowledged the enduring community and camaraderie he fostered. Ryan Pagell, leading the hike that Friday, remarked on Seman’s perpetual presence in spirit.
Barry Tharp, 66, recalled meeting Seman on the same trails eight years prior, noting his unique vibrancy and blend of Christian faith with scientific expertise. Seman was also dedicated to boosting the region’s monarch butterfly population.
Along with his seasonal “Monster Dune Challenge,” a 22-mile trek through the state park, Seman’s dedication extended to multiple daily hikes. Ed Oziminski, 43, recalled his last hike with Seman amidst grueling heat, a poignant memory of their friendship’s final moments.
Marcella Bernat, 71, shared how Seman’s encouragement helped her through a period of grief. His invention earnings allowed him to retire early and indulge his passions, benefitting many like Bernat who found solace in nature.
At the beach’s west end, Connor Zelasko, 33, organized a memorial circle. Despite initial setbacks, his petition to name a dune after Seman gathers momentum, representing Seman’s profound impact on the community, including those in recovery groups.
Zelasko reflected on his immense loss, acknowledging the myriad others who felt the same. He viewed Seman as a significant mentor and friend, leaving a legacy of connection and healing through nature.
