These map units are based on the Snowy River Volcanics geological formation which have a number of lithologies; predominantly acid volcanics (rhyodacite). The Type 2 units consist of a greater proportion of red ignimbrite, some coarse sandstone and conglomerate compared with the Type 1 and Type 3 map units and also occupy the driest areas on the acid volcanics lithologies. There is also a limestone outcrop at Jackson's Crossing. A major geomorphological feature is the incision of the Snowy River and some of its tributaries into much of this geological formation. The soils tend to range from reddish friable gradational profiles to drier shallow, very stony uniform/gradational profiles. The vegetation is Dry Sclerophyll Forest, Rain-shadow Woodland, some Wet Sclerophyll Forest and Warm Temperate Rainforest. Geology: Dls; Devonian acid volcanics (Snowy River Volcanics). Rhyodacite, tuff, andesite, minor rhyolite and basalt. Also includes coarse sandstone and conglomerate, minor siltstone. Minor limestone (Dla). Rainfall: Less than 700-1000 mm per annum. Slope: 10-greater than 100%, generally 10-32% Dominant landform element: Broad crest, slope Minor landform element: Drainage depression |
