10 -NOTES ON MT. ANNE AND THE WELD UIVER VALLEY, 



for an investi,q:ation of geolojry were few, but these frag;- 

 mentary notes may be of assistance to future investigators. 



(b) Geological Position and Access. 



Mt. Anne lies about 45 miles due west from Hobart, 

 near the head of the Huon River. From the top of the 

 Tyenna Valley a line of rough hills runs westward from 

 Mr. Mueller through Mt. Wedge to the Valley of the Serpen- 

 tine. Farther west the rugged and almost unexplored Frank- 

 land and Arthur ranges bar the way to the West Coast and 

 Port Davey. South of Tyenna, running towards the Huon 

 Valley, is a confused mass of hills of varying height which 

 to the east join up with Mt. Wellington. Between these 

 two ranges is a large basin, twenty miles across in every 

 direction, in the centre of which rises Mt. Anne, the most 

 outstanding peak in South-West Tasmania. It is the highest 

 point of a short ridge which extends on every side in a 

 number of spurs. To the west is the broad, flat, swampy 

 valley of the Huon, which passes without a perceptible divide 

 across to the Serpentine, flowing from Lake Pedder to the 

 Gordon. To the east runs the River Weld in a series of 

 gorges and steep-sided valleys all filled with almost impene- 

 trable jungle. 



The area reviewed in this paper extends from the 

 vicinity of Fitzgerald on the Russell Falls River^ on the 

 north, to the junction of the Huon and Weld rivers, on the 

 south. These points are approximately the end of cultiva- 

 tion in this part of Tasmania. The area is bounded on 

 the west by the Huon River. 



Mt. Anne lies over thirty miles beyond ths point to 

 which roads have yet been pushed, and there is no natural 

 feature giving ready access. The easiest route to the 

 mountain is along the Tyenna-Port Davey track, which, 

 starting where the southern road from Fitzgerald ends at 

 Mayne's selection, winds round Mt. Mueller and Mt. Bowes 

 to the Huon Plain.s, and eventually crosses the Huon River 

 25 miles from the end of the road. The track is a good one 

 till it crosses Mt. Bowes and is at present passable for pack 

 horses. On the Huon Plains, however, it is in a general 

 state of disrepair, with bridges down and overgrown with 

 bauera scrub and other obstaclc«. From the point h\, which 

 the track crosses the Huon, Mt. Anne can be reached across 

 open buttongrass plains. The second of the two western 

 spurs presents a possible route to the summit of the Mt. 

 Anne plateau.
