Dark blue North Face backpack with orange zippers

I lost my dark blue North Face backpack yesterday around 3pm near the Susanville Library on Lassen Street, outside the coffee shop by the crosswalk. It's a medium-sized pack with a slightly worn exterior and bright orange zipper pulls that are easy to spot. Inside there's a galaxy-print lining, a red silicone fox keychain on the front zipper, and a 'Trail Scout' patch on the front pocket. It also has a small sticker with my sister's initials on the inner pocket, and it has sentimental value—my grandmother gave it to me, and I really need it back.
