Open tracts on the Columbia County ArcGIS parcel map usually carry little or no building value, which helps when scanning around Umatilla National Forest.
The free map to start with
Lots and tracts near Covello appear on the Columbia County ArcGIS parcel map, a viewer that needs no account. For property near Turner, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a parcel near Jackson, save the parcel ID from that panel; every office in the county will want it.
Is the tract reachable?
Acreage on the record is assessed, not surveyed, so a survey for the tract near Huntsville is worth it.
Mineral and timber rights
In some areas, mineral or timber rights near Starbuck can be sold separately, which a title search can uncover.

Places you'll see on the map
Dayton serves as the county seat, home to the main records offices. Smaller places on the map include Starbuck, Covello, Jackson, and Huntsville, where town lots give way to larger tracts. Around 4,053 people live in Columbia County (Census estimate, 2023) spread over about 869 square miles. The county was formed in 1875, which matters when you trace an old farm's title, at least around Umatilla National Forest. Landmarks such as Umatilla National Forest help you orient on the aerial.
Offices that can help
Anything recorded against property around Jackson sit in the index kept by the County Auditor, often with an online index. Questions about what you can build around Marengo need the planning or permitting office, town or county, depending on location.
On the ground
Visit the tract near Jackson at different times, and check cell signal and internet options; the map won't tell you that.
Flood, wetlands and soils
Check the tract near Starbuck on FEMA's Flood Map Service Center for mapped flood zones; the National Wetlands Inventory mapper gives a first look at wetlands.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Starbuck, but coverage can be spotty out of town. A printout of the tract near Huntsville keeps working without signal.
Deeds, plats and who keeps them
For anything that matters, pull the recorded deed from the County Auditor; the parcel line is a drawing of it, which applies near Umatilla National Forest as much as anywhere. Older tracts near Umatilla National Forest may trace back through several deeds, so a title company is worth hiring before a purchase.
How land is described here
Washington follows the Public Land Survey System, which means a tract near Turner is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Marengo can be irregular. Copy the legal description from the record for the parcel near Covello when you talk to a surveyor.
Taxes and land use
Check what uses are allowed on ground near Jackson before you commit.
Before you lean on the lines
For a home near Dayton, listed acreage is an assessed number; just a licensed surveyor establishes the real corners on the ground. Near Huntsville, records update in batches, so a deed recorded last month might lag behind.
