Lost gray and blue backpack with a mountain range patch near the wetlands in Elmira-Corning.

I lost my favorite gray and blue backpack while walking my dog along the paths near the wetlands in Elmira-Corning. It has a distinctive patch of a mountain range sewn on the front and contains some personal items, including a water bottle and my notebook. I realized it was missing when I got home and misplaced my keys, which were in the backpack. If anyone finds it, I'd really appreciate your help!
