From the lots in Sun Valley to the back roads near Galena, the Blaine County GIS map shows who owns what and roughly where the lines fall.
The sections below cover the map itself, the towns from Sun Valley to Galena, and the deeds and surveys that settle what the map can't.
How to use the Blaine County GIS map
Open the statewide Idaho statewide Parcels layer in ArcGIS Map Viewer and zoom toward Carey; Blaine County's parcels are part of that layer. Zoom until the lot lines show up around Ketchum, then click; the pop-up gives the parcel ID, owner and acreage. If the official link ever moves, the Blaine County page on Platbookmapper keeps the current version.
Towns, terrain and land across Blaine County
Parcel searches in Blaine County tend to center on Hailey, the county seat, plus Bellevue, Carey, Ketchum, and Sun Valley. Smaller places such as Gannett, Galena, and Gimlet show up as clusters of lots along the roads. Blaine County was created in 1895 and takes its name from James G. Blaine. The Census Bureau puts Blaine County at about 2,638 square miles of land and an estimated 25,041 people (2023). Click anywhere between Sun Valley and Carey and you are likely to land on a big ranch, farm or timber parcel rather than a house lot. On the parcel layer, Craters of the Moon National Monument and Minidoka National Wildlife Refuge show up as public ground, and the private tracts along their edges are worth checking line by line.
Who uses the Blaine County parcel map
A lot of different people around Carey rely on this map. Hunters near Carey check the lines before opening day so a blood trail or a retrieve doesn't cross onto a neighbor's ground uninvited. People hunting for a few acres outside Sun Valley use the parcel layer to sort tracts by size and spot ones with good road access. Current owners in Blaine County pull their parcel before a tax appeal, a refinance or a talk with the neighbor about a fence.
How to find property lines in Blaine County
Lines on the map show roughly where one parcel near Ketchum ends and the next begins; the exact spot is a surveyor's call. Because Idaho is a section-township-range state, the legal description of a rural tract in Blaine County reads like a grid reference that you can match to the section lines on the map. For a fence, an addition or a dispute in Blaine County, budget for a licensed survey; it's the answer a court or a lender will accept.
Behind the map: land records in Blaine County
Every line on the Blaine County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Check the county government website to see which office records deeds for land near Galena. If you need a plat for a lot in Carey, look for the plat book and page or the subdivision name in the parcel record, then request that document from the recording office.
Work and land use in Blaine County
By the Census Bureau's 2022 count, 1,718 business establishments operated in Blaine County. Construction had the most, followed by professional and technical services and real estate and rental and leasing. Relative to the U.S. as a whole, Blaine County is heavy on air transportation, furniture manufacturing, and building construction. Manufacturing jobs in the county help keep house lots and small acreage in demand, including around Hailey. Keep that in mind when you compare parcels in Blaine County: who works here shapes what land sells.
Private and public hunting ground in Blaine County
Most hunting ground in Blaine County is privately owned, and the parcel map is how you find out whose it is. Around Craters of the Moon National Monument and Minidoka National Wildlife Refuge, private tracts can press right up against the public boundary, so check the lines before you walk in. The Idaho Department of Fish and Game handles licenses, seasons and public-land maps for Blaine County. A landowner near Galena is more likely to say yes to a hunter who names the exact parcel and offers a phone number.

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.
