Three Sisters above Jamison Valley in the Blue Mountains
Published on 09/19/2026 at 09:26 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
On the sandstone rim above Jamison Valley in Australia, Three Sisters forms a clear row of peaks along the Blue Mountains escarpment near Katoomba, where rock and story share the same edge of cliff. Rising a little above 900 m (about 3,000 ft) above sea level, the three towers stand side by side on the valley brink rather than isolated in the basin, turning a single stretch of cliff into a line of separate heights.

Geology shaped by erosion above Jamison Valley
The rock of Three Sisters formed as layers of sand and silt settled onto an ancient sea floor, later compacted into sandstone and shale that rose as a plateau across this part of eastern Australia.layers of sediment that gradually created rock beds Water and weather then cut into joints and bedding planes in the sandstone, breaking sections of cliff away from the plateau and leaving them as standing columns on the valley edge.
Jamison Valley falls away directly below the formation, so the three towers stand in a line between the flat ground of the plateau and the forested slopes of the valley basin.cliff edge above Jamison Valley The sandstone itself is marked by horizontal bedding, weathered faces and vertical fractures, carrying the same pale colours and dark streaks seen along other cliffs of the Blue Mountains.
