The Mount Stromlo is a 770 meter high hill in Australian Capital Territory in Australia . Located west of downtown Canberra , on the outskirts of the Weston Creek borough , it is known as the site of the renowned Mount Stromlo Observatory . Nearby is the Cotter River , which is dammed by three dams and is the city's main drinking water supply.
description
The rock of Mount Stromlo consists of ignimbrite from the Laidlaw volcanic group. This erupted in the Upper Silurian about 420 million years ago over the rhyodacite of the older Deakin volcanic group and is visible on the surface on the lower slopes of the east and south-east side. The northern lower slopes are covered with a calcareous schist, which is included in the Laidlaw volcanic group because it was deposited at the same time. He is the Winslade- on the northwest side warp cut off the northeast leads to the districts Cook and Kaleen. A branching fault leads east from Winslade Fault to below Scrivener Dam . On the northwest and north sides of these faults there are middle-Silurian rhyodacite volcanic deposits from the Walker volcanic group. Compared to the south side, the north side has been raised.
The notch height is almost 200 meters. The Stoney Creek and its tributaries drain the north side of the mountain, the east side is drained to the Molonglo River . The south side feeds the Blugar Creek, which flows into the Murrumbidgee River . The summit is elongated in a north-south direction, with a spur running to the southwest, where there is a water reservoir. The name Stromlo comes from the verses of Ossian .
observatory
The Mount Stromlo Observatory , operated by the Research School of Astronomy and Astrophysics at the Australian National University , has stood on the summit since 1913. The forest on Mount Stromlo burned down completely in the devastating bushfires in January 2003 . The fire also destroyed the observatory and the water reservoir. The buildings were restored over a period of twelve years and have been open to the public again since January 2015.
Sports
Mount Stromlo is considered to be the center of Australian mountain bike sports. Around the mountain there are trails with a length of 50 kilometers, which are maintained by volunteers. After the Canberra Off-Road Cyclists association had repaired the trails that had been destroyed by the bushfires, it presented the candidacy for the 2008 Mountain Bike World Championships together with the Australian Cycling Federation . However, the UCI awarded this to the Val di Sole in Italy . After all, the 2009 Mountain Bike World Championships took place on Mount Stromlo .
