Getting oriented in Mono County
Mammoth Lakes fill out the town list, and Bridgeport is where the county seat sits. By Census Bureau figures, the county had roughly 13,066 residents in 2023, spread over about 3,049 square miles of land. Sparse settlement means wide parcels. Outside Mammoth Lakes the county map reads as a quilt of large holdings with long gaps between houses. Terrain such as the White Mountain Peak explains why some parcels are long and narrow while others follow ridgelines.
Where to find the official Mono County GIS map
For parcels from Aspen Springs to Coleville, the Mono County parcel viewer is the county's own public map. A parcel number from a Mono County tax bill is the most precise search; failing that, an owner name or a click on the map near Aspen Springs works. We keep the link current on our Mono County (CA) directory page, next to the neighboring maps.
How to find property lines in Mono County
Zoom in far enough on a lot in Mammoth Lakes and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Out past Bridgeport, rural deeds usually cite a section, township and range, and those section lines often show on the parcel layer. A survey is the only document that settles where a Mono County boundary actually runs.
Behind the map: land records in Mono County
The map near Aspen Springs is only as good as the deeds behind it, and those are kept in the county's recording office. Recording offices go by different titles from state to state, including register of deeds, recorder, county clerk and clerk of court; the official Mono County website names the one that handles deeds. For subdivision lots in Mammoth Lakes, the plat book and page on the record leads straight to the recorded plat.
Who uses the Mono County parcel map
For a hunter with permission on one farm near Bridgeport, the parcel map shows exactly where that permission stops. Land shoppers looking between Mammoth Lakes and Bridgeport measure road frontage on the map and check whether a tract is landlocked. Rural owners near Coleville use the map to see how many acres the county has on record for them and who owns the land next door.
Private and public hunting ground in Mono County
The woods between Mammoth Lakes and Coleville can look like one block from the road, but the parcel layer often shows several owners. The California Department of Fish and Wildlife handles licenses, seasons and public-land maps for Mono County. Ask owners near Aspen Springs early, ask politely, and send a thank-you after the season.

Recreation money shows up in the Mono County land market as demand for cabin sites and small getaway parcels.
Two things the map won't tell you
A lot in Aspen Springs that sold last month may still show the previous owner on the map. Acreage on the Mono County map is a tax figure; a survey is what a lender or buyer should rely on.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
