Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:	297135. Three kilometres east of the Snowy River on a tributary of Gattamurgh Creek near the N.S.W. border.
Abstract:	Block streams.
Access:	This is difficult from Victoria, as it involves crossing the Snowy River near the N.S.W. border. Alternatively, four-wheel drive tracks from Tingaringy may be used, by these are not shown on the 1:100:000 sheet.
Ownership:	Crown Land (Tingaringy National Park)
Geology/Geomorphology:	The area has not been visited on the ground, but aerial photograph interpretation indicates that block streams or rock rivers are developed on the slopes of the two main ridges that extend into New South Wales, north of Gattamurgh Creek. The patterns on the photographs suggest these factors are comparable to the block stream of Mt. Cobberas, Big Hill and Mt. Wombargo and there is also distinct amphitheatre from developed at the heads of small valleys on these ridges. The geology is not known in detail by the bedrock of the area is shown on existing geological maps as undifferentiated Upper Ordovician sedimentary rocks. Probable smaller block streams to the south are on granitic rock.
Significance:	Unknown (possibly State). If the features are true block streams and not simply talus or scree slopes, they would represent a major block stream locality on a rock type not previously recorded as susceptible to development of this landform.
Management:	Further investigation of the composition and morphology of the ‘block stream’ is needed before management guidelines can be proposed. No road works or removal of rock material should be permitted until such research is undertaken.
