The printed Elmore County plat book and the online parcel map answer the same question, who owns the land near Mountain Home, in different ways. Here's what a plat book is, where to look for one in Elmore County, and the free official map that stays current between editions.
How to use the Elmore County plat book
A plat book, sometimes called a land atlas, displays each township in Elmore County as a page, with ownership blocks labeled by owner name and rough acreage. It's different from a recorded plat, which is the official survey drawing for a subdivision in Glenns Ferry filed with the county.
Finding the tract on the Elmore County map
The county's own public map is the Elmore County ArcGIS parcel map, built on an Esri ArcGIS web map, and it opens without an account for parcels in Hammett and the rest of the county. Use the search box for an address in Hammett or a parcel number, or simply zoom in and click a tract around Glenns Ferry. Bookmark our Elmore County page too; it tracks the official Idaho link if it moves and lists the maps around Hammett.
Current and older editions
Whether a current Elmore County edition exists varies, so ask locally in Glenns Ferry before ordering; county offices commonly know if one is in print. An old atlas can help trace when a tract around Mountain Home split off from a larger farm.
Current owners without a printed book
Between editions, use the Elmore County ArcGIS parcel map; it displays owners, acreage and parcel IDs for land near Mountain Home at no cost. Phone signal can be thin near Atlanta, so save the parcel IDs you need before you head out.
Recorded documents in Elmore County, Idaho
The parcel layer for Elmore County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). Easements and access rights near Glenns Ferry live in recorded documents, so read the deed, not just the county map.
What a plat book page displays near Mountain Home
Plat book pages for Elmore County typically include an index of owners, so you can find a family name near Glenns Ferry without knowing the township. Acreage printed in a county atlas is rough; the deed and a survey decide the real figure for a tract around Glenns Ferry. If you use a plat book for hunting permission near Mountain Home, recheck the titleholder on the county map first.
Making your own atlas of Elmore County
Names in an older Elmore County atlas can lead you to the right deed in the grantor-grantee index for land near Atlanta. If you can't find a printed edition, a screenshot of each township from the county map serves as a handy homemade atlas for the area around Hammett.
