HICKEY'S CREEK DISTRICl'. 



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

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

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

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

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

 tlie features, with the result that some interesting structural points 

 are brought out, marking a powerful tectonic lin6 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 vehicvilar 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
