Stonehenge is a small settlement (population 40) just off the Thomson Development Road between Longreach and Jundah. The township is near the Thomson River but far away enough to be clear of most flooding. This is primarily a cattle grazing region with some opal mining as well as oil and gas development. The name arose after drovers established a stone enclosure near the river for use while droving cattle; the enclosure has gone but the name remains. The 4WD John Egan Pioneer Track provides access to scenic, but rough, upland country a few kilometres from Stonehenge. Lochern National Park, north of Stonehenge, contains an interesting variety of native plants.
