HICKEY'S CREEK DISTRICl'. 



This is a relatively small area on the eastern side of the Macal- 

 lister valley, at Hickey's Creek junction, about twelve miles from 

 Glenmaggie (see Map 3). It lies on the route from Heyfield to 

 Mount Wellington, via the Macallister Valley, and therefore had 

 been frequently traversed during the journeys to- and from the- 

 Wellington region. 



Here particularly, as well as at other points further north in the' 

 Macallister Valley, the Upper Palaeozoic rocks had been noted to be 

 very highly inclined, with dips ranging up to nearly vertical, and 

 sometimjes in the reverse direction to the normal one. It was 

 therefore decided to give a little time to a more detailed study of 

 the features, with the result that some interesting structural points 

 are brought out, marking a powerful tectonic line running approxi- 

 mately N.N.W., and probably continuing for a great distance in 

 this direction, coinciding very closely with the western boundary 

 of the Upper Palaeozoic series. A new road for vehicular traffic 

 in place of the old pack track has recently been made as far as the 

 junction of Target Creek with the Macallister, about thirty miles 

 from Glenmaggie. At Hickey's Creek, this road leaves for a time
