Blue North Face backpack with orange zipper

I lost my blue North Face backpack yesterday around 3pm. It's a medium-sized cadet blue pack, with bright orange zipper pulls and a small red enamel pickaxe pin on the strap. Inside there's a gray fleece, a stainless steel water bottle, and a folded trail map. I think I left it near the Orphan Girl Brewing on Main Street in Uptown Butte, close to the old Mining Museum and the corner with Quartz Street. It has sentimental value—it's my hiking bag from a trip with my grandfather, and I really need it back. If anyone found it, I'd really appreciate getting it back.
