Charcoal gray North Face backpack with red zippers

I lost my charcoal gray North Face Borealis backpack yesterday around 3pm near the Town Square on West Broadway in Jackson, Wyoming. It's a 26-liter backpack with water-resistant fabric, a black bottom panel, and bright red zipper pulls. There’s a white pine-tree patch on the front pocket and a small blue enamel compass pin inside the main pocket. The bag shows light wear on the bottom but is otherwise in good shape and it holds my camera charger and a folded photo that’s sentimental—my grandmother gave it to me. It has sentimental value and I’d be really grateful to get it back.
