Mammoth Lakes lost and found resources
Where your lost items typically end up, and how ReportLost connects you

Town of Mammoth Lakes
The Town's administrative offices can help direct your lost item report to the right department and may have insights on where items turn up in local facilities and parks.
Mammoth Yosemite Airport
If you lost something at the airport terminal, contact them directly. We can include airport details in your report to ensure they're aware of what you're looking for.
Lost pet? We have you covered.
If your cat, dog, or other pet is missing, Whitmore Animal Shelter and Mono County Animal Services are your first stops. They also work with community networks like Mammoth Missing Pets and Inyo/Mono Lost and Found Pets on Facebook.

Getting ahead after a loss
The sooner you report, the sooner your item can be matched with found reports and community tips. Once you've filed with ReportLost, the work of coordinating with police, shelter staff, and local groups is already underway, and your report continues searching on your behalf.
Report my lost item →Mammoth Lakes residents know how easy it is to misplace something in the mountains, whether you're at a trailhead, in town on Main Street, at the ski resort, or even at the airport. Between the Police Department, Whitmore Animal Shelter, local transit, and scattered community groups on Facebook and Reddit, figuring out where to report your loss can feel overwhelming.
ReportLost simplifies the whole process. File once, and we make sure the right people know about your loss. We get your report to the Police Department's lost property system, route it to the places most likely to have it, and post it where the community can help. Then your report stays active in the background, automatically cross-checking new found items and community posts for months, so you can focus on your day instead of refreshing websites and groups hoping for a match.
