Ground near Colorado River or a house lot in Moab: either way, the Grand County plat map is the free starting point for owner names, acreage and lines.
We'll cover the official map, the communities and terrain around Moab, how property lines work in Utah, and where the deeds come from.
Towns, terrain and land across Grand County
Start your bearings with Moab, the county seat, then Castle Valley. The county was organized in 1890 and named for Grand River (now the Colorado River), so some tracts carry a long chain of deeds. Roughly 9,706 people (Census Bureau, 2023) share Grand County's 3,673 square miles of land. Between Moab and Castle Valley the parcel lines open up into large holdings, some running to hundreds of acres. Parcels touching the Colorado River tend to run long and narrow back from the water, a pattern you can see clearly on the Grand County map. Public ground such as Arches National Park, Canyonlands National Park, and Dead Horse Point State Park appears as large unbroken blocks, and the private parcels around them draw hunters and recreation buyers.
Getting into the Grand County ArcGIS parcel map
Grand County's public parcel map is the Grand County ArcGIS parcel map, hosted on an Esri ArcGIS web map. Try the search box with a Castle Valley street address first; for open land near Mesa, it's faster to pan and click. We keep the link current on our Grand County (UT) directory page, next to the neighboring maps.
What the Grand County plat map shows about lot lines
Zoom in far enough on a lot in Moab and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Out past Thompson Springs, rural deeds usually cite a section, township and range, and those section lines often show on the parcel layer. If a neighbor's fence near Thompson Springs and the map disagree, neither one is proof. A survey is.
Where Grand County deeds and plats are kept
The map near Castle Valley is only as good as the deeds behind it, and those are kept in the county's recording office. The office title varies by state (register of deeds, recorder, county clerk or clerk of court), so check the Grand County government website for the right one. If the Grand County parcel record shows an instrument number, that number is the shortcut to the recorded deed.
Who needs this map
The same map serves very different jobs around Moab.
- Turkey hunters near Thompson Springs use the map in spring to confirm which fields their permission actually covers.
- A buyer who wants ten or twenty acres near Castle Valley can rule out most of the wrong tracts from a desk before driving out.
- House hunters looking at Thompson Springs use the parcel record as a free check on the listing: lot size, legal description and last recorded sale.
Hunting land and landowner permission in Grand County
Near Castle Valley, a single field edge can separate two owners with very different answers about access; the map tells you which is which. Hunters headed to Arches National Park and Canyonlands National Park should check where the public boundary ends; the tracts beyond it are private. Before hunting around Castle Valley, read the state wildlife agency's current season rules. Ask owners near Castle Valley early, ask politely, and send a thank-you after the season.
The Grand County economy in brief
Of the 556 establishments the Census Bureau counted in Grand County for 2022, the biggest groups were accommodation and food services, retail trade, and construction. Compared with the nation, the county has an unusually high share of businesses in scenic and sightseeing transportation, accommodation (hotels, motels, RV parks and camps), and amusement, gambling and recreation. That usually means steady interest in cabin lots and recreation parcels around Thompson Springs. It's useful background when you're judging whether a tract near Castle Valley will hold its value.
Data limits to keep in mind
Splits and sales near Mesa can take weeks or months to show up on the parcel layer. The acreage on a Castle Valley record is what the tax roll uses, and a survey can come out different.
