Lost pair of blue medium-sized snowboarding gloves with a small wrist strap near a bench at Pictured Rocks National Lakeshore.

I lost my favorite blue snowboarding gloves while visiting Pictured Rocks National Lakeshore in the Upper Peninsula. I think I accidentally left them on a bench near the viewing area after taking some pictures. They're size medium and have a small wrist strap. I would really appreciate their return as they were a gift from my sister.
