the amount of faulting from Kiandra to Paradise Flat and 

 also of the recency of such action. Under Kosciusko the 

 river Hows in a peculiar and Hat-floored valley. The latter 

 is hemmed in to the west by the mass of Kosciusko whose 

 summit rises 4,300 feet above the Snowy valley floor. 

 Through two profound canons the Thredbo and the Snowy 

 of the maps leave the mountain pile of Kosciusko and enter 

 the curious and broad ilat-lloored valley under discussion. 

 Kastward the valley rises steeply to the Monaro level and 

 the valley side is trenched here and there with tiny canons 

 which reach the Snowy valley as cascades. 



Rising ground appears to block the river below Jindabyne 

 but iu reality the stream pierces the obstacle by means of 

 a gorge. Alluvial terraces 1 in the broad valley floor indi- 

 cate a tiny lake only just drained by the deep gorge which 

 has almost reached Jindabyne. The trench deepens down 

 stream and pierces a large fault block forming a wall to a 

 broad and high senkungsfeld (3600 ft.) now drained by the 

 Mowaniba. From the lip of the ravine by which the stream 

 traverses this range, the country may be seen to fall away 

 steeply to a low lying plateau surface at Dalgety. Thence 

 the Snowy may be seen approaching a great mountain pile 

 (fault block) to the south, which it penetrates in turn in 

 profound ravines. 



It would thus appear that the course of the Snowy has 

 been much altered by the activities of the "Kosciusko" 

 Period. Great block faults have been thus formed in the 

 Snowy River district. Such faulting has been described
