|Low hills and low outlying ridges are usually continuations of the dividing ridges of the main drainage systems. The Warby Range is the northern end of the divide between the Ovens River and the Broken River catchments. Further to the west, the Lurg hills mark the divide between Ryans Creek (a tributary of the Broken River) and Fifteen Mile Creek (a tributary of the Ovens River). The knot of low ridges and hills of the Leneva hills form the divide between Indigo Creek, (a small tributary of the Murray River) and the Kiewa River. |
Local relief is usually no more than about 200 m and slopes are moderate with rounded crests and concave lower slopes grading via alluvial/colluvial fans into valleys, often with ephemeral streams, or merging into the margins of Tier 1.3.3 or either the Northern Riverine Plains (Tier 4) or the Eastern Plains (Tier 7).
Mt Dandenong (618 m) in Devonian dacites and the Cathedral Range (c. 1000 m) near Buxton, composed of hard Devonian sandstone, are outlying eminences rising sharply above their surroundings.
