Union County elevation and terrain tools
Eastern Oregon • County seat: La Grande
Union County centers on the Grande Ronde Valley, a broad flat basin around La Grande ringed by the Blue Mountains and the Wallowa Mountains. The valley floor is nearly level, and the slopes rise sharply on every side.
Open the mapLidar coverage
Lidar projects that cover La Grande, from the USGS 3DEP index and DOGAMI’s project records. Other parts of the county may come from other projects; the coverage guide explains how to check any spot.
Coverage details are temporarily unavailable.
Property boundaries
The county assessor’s parcel service for Union County is not available in the Property tool yet, so taxlots cannot be selected here. Draw your area on the map instead; the parcel lines overlay still shows taxlot lines.
