Grey North Face backpack with orange zippers

I lost my grey North Face backpack yesterday around 3pm near the Weatherford Hotel on Route 66 in downtown Flagstaff. It's a Borealis-style backpack, medium size, with orange zipper pulls and a blue paracord loop on the top handle. There's a small green cactus-shaped keychain attached to the zipper and a faded patch on the front pocket. Inside I had a spiral notebook and my laptop sleeve, plus a few hiking maps; it feels sentimental because it carried my field notes from last summer. If anyone found it, please drop it off somewhere safe or contact me—I'd really appreciate getting it back, especially before this weekend's hike.
