Towns, terrain and land across Union County
Besides El Dorado, which serves as the county seat, the map covers Calion, Strong, Huttig, and Junction City. You'll also find unincorporated communities, among them Lawson, Mount Holly, and Urbana. The county dates to 1829, and older deeds may still refer to landmarks from that era. Roughly 37,397 people (Census Bureau, 2023) share Union County's 1,039 square miles of land. Town lots in Junction City give way to farm tracts and woodlots within a mile or two, and the roads toward Norphlet are lined with small acreage splits. The Ouachita River is part of the Union County landscape, and creek or shoreline tracts are common there. Public ground such as Felsenthal National Wildlife Refuge appears as large unbroken blocks, and the private parcels around it draw hunters and recreation buyers.
Are the Union County property lines accurate?
Zoom in far enough on a lot in Junction City and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Rural Union County land sits on the federal survey grid: a deed might call out a quarter of a numbered section in a given township and range. Corner pins, a recorded plat and an Arkansas licensed surveyor beat any line on a screen.
