| Description |
The Galada Tamboore grasslands are of significance for it's remnant fauna and flora and biological diversity. Galada Tamboore is derived from Wurundjeri words for 'creek waterhole'. The area was originally reserved by Melbourne Water as a retarding basin but it now forms part of the new Merri Creek Parklands. The Merri Creek Management Committee describes the features: "The major geomorphological and geological feature is a 15 metre high cliff on the right bank of the Merri Creek. This cliff exposes an unconformity between the bedrock of Silurian sedimentary rocks and the Newer Volcanics basalts. The Silurian rocks outcrop in the channel of the creek and along with large fallen basalt blocks, form rapids and small cascades when the rivers is in high flow. A number of small potholes are eroded into the sandstone beds, some with basalt grinding pebbles still in place. In the cliff face can be seen the fossil soil developed on the Silurian rocks and now buried and baked by the lava flow. A calcareous precipitate forming a massive deposit on parts of the lower cliff is a result of carbonate rich waters issuing as springs at the base of the basalt. Different flow structures and joint patterns in the lava indicate more than one flow unit to be present in the cliff face." "This gorge is one of the most distinctive topographic features of the Merri Creek catchment and a major element of the landscape of the northern region of Melbourne. It is an outstanding example of an unconformity between basalt and the Silurian bedrock - a very common geological feature but one which may be seen in only a few localities. Both rock types and the contact in the cliff face on the right bank of the Merri Creek are well displayed and a number of related features (buried soil, ground water leakage and carbonate deposition) are also evident. The site is the best example of this geological feature in the Melbourne region and is a superior display than the better-known similar feature at Organ Pipes National Park." You can discern the Hume Freeway on the horizon. |
