Petermann Ranges : Australia

 

PETERMANN RANGES : AUSTRALIA

Located 10km from the border with Western Australia, Kaltukatjara is a remote Indigenous Australian community in the Northern Territory.

The community is on the north side of the Petermann Ranges on a wadi called Docker River, which originates from the confluence of smaller creeks at the break in the ridgeline.

The Petermann Ranges run 320 km (200 miles) and were formed about 550 million years ago. They were once equivalent in height to the Himalayas, with their highest point now at 1,158 metres (3,799 ft). The Grand Central Road of Western Australia becomes the Petermann Road once is crosses the border in to the Northern Territory.

This road continues Eastward passing near Uluru, Ayers Rock, which is an inselberg created by sand deposited as part of an extensive alluvial fan from the Petermann, Musgrave and Mann Ranges. At a distance of 230km (144 miles), it would take over 8 hours to make the drive over the less than ideal road conditions.


The inset photographs were taken using an 1150mm lens from the Cupola of International Space Station. This is the 2nd post in a series using a selection of images taken during one pass over the continent.

The two overlay photographs were taken 6 seconds apart, during which time the @iss traveled* 43 km (27 miles) (*Between Nadir Points : distance over ground) on a SW-NE pass across the intersection of the Western, South and the Northern Territory Regions of Australia. The images are 14 km (8.75 miles) apart and were taken in opposing directions from the pass.

The shadows coming off the ridgeline in the photographs align with the sun position, which was at a low altitude of 23° and had an azimuth of 303° (WNW).
