Memorial Hike Honors Indiana Dunes Advocate, Ron Seman

On a Friday night under clear blue skies, a group of about 25 people gathered for a memorial hike at Indiana Dunes State Park. They were there to honor Ron Seman, a beloved figure in the Indiana Dunes hiking community. Seman, known as a trailmaster, led many on the park’s scenic trails, sharing knowledge and building friendships.

This event took place on July 24, 2026, marking the first memorial hike since Seman’s passing on June 26 at 64 years old. The participants, including his widow Susan Seman, navigated Trails 9 and 10, which offered stunning views of Lake Michigan. Despite her health challenges, Susan joined the hike to remember her husband and celebrate his life.

Following the hike, the group gathered on the beach, where they shared stories as the sun set in a brilliant orange glow. Tiffany Yorek, a regular hiker, expressed how Seman created lasting bonds among participants. She emphasized that the friendships formed on hikes would continue to preserve his legacy.

Ryan Pagell, who led the hike that evening, said, “He is going to be with us on every hike here and forever.” Pagell’s sentiment was echoed by Barry Tharp, who recounted meeting Seman eight years prior and described him as unique and passionate. Tharp highlighted Seman’s deep faith, scientific expertise, and commitment to nature conservation, particularly in boosting the monarch butterfly population in the region.

Seman organized the “Monster Dune Challenge,” guiding adventurers across all 22 miles of park trails throughout the year, including winter. Ed Oziminski fondly recalled one of Seman’s final hikes, when soaring temperatures led the group to cool off in Lake Michigan.

Marcella Bernat spoke about how Seman’s encouragement helped her heal from the loss of her husband. Spending a year outdoors with Seman, she found solace and presented him with a painting of him canoeing into the sunset.

Connor Zelasko, organizing a petition to name a dune after Seman, shared his experience leading addiction recovery hikes. Zelasko viewed Seman as an inspiring figure who urged others to connect with nature and each other, helping rebuild their lives.

The loss of Seman was deeply felt. Those who walked with him remember the joy and knowledge he imparted. His influence extended beyond the trails, touching many lives and forming a lasting community.
