quartzites and can be followed on the inside of the curve made by 

 the altered strike of the quartzite ridge. In this district the glacial 

 till is rotten and has weathered down in most places to a soil pos- 

 sessing good agricultural qualities. 



Near Mr. Hazel's house, in Sections 134 and 137, Hund. of 

 Kapunda, huge blocks of harder tillite rise above the cultivated 

 ground having the appearance of monoliths. Large granite bouldeii3 

 occur both free and in situ in the till. One that was dug out 

 measures 4 feet 6 inches, by 3 feet 6 inches, by 3 feet. The till near 

 Hazel's is light-coloured and, amongst other erratics, contains 

 numerous angular fragments of a dark-coloured crypto-crystalline 

 limestone. Near the upper limits of the till are grits and quartzites, 

 which are quarried. 



The glacial beds cross the River Light, and are well exposed 

 in a railway cutting, about a mile and a-half north of Ford's Railway 

 Station. Here the beds are about half-a-mile in width, varying 

 in texture from a fine-grained sandstone to coarse grits. The 

 erratics are not very numerous in this exposure and occur mostly in 

 groups or pockets. One granite example, seen in the fifth cutting 

 from Ford's, measured 3 feet in length. 



In superior order, the Tapley's Hill slates are met with on the 

 northern side of the glacial outcrops, and these continue over an 

 extensive peneplain of agricultural country for a distance of 24 

 miles to Eudunda, where the glacial beds once more appear in a 

 return fold. The town of Kapunda is situated on the Tapley's Hill 

 slates and the once famous Kapunda Copper Mine was worked in 

 the latter. 



At Eudunda, 21 miles north of Kapunda, the glacial beds occur 

 in a relatively fiat country and exhibit only slight relief in the 

 physical contours, so that outcrops have to be looked for in small 

 quarries or in the sides of the creeks. The Eudunda township is 

 built on these beds, which follow a north-westerly and south-easterly 

 strike along the flanks of a low range which makes the division 

 between the Hundreds of Julia Creek and Neales. The outcrop was 

 followed in a south-easterly direction for seven miles, when, in its 

 passage into the Hundred of Button, the strike once more becomes 

 due north and south, which is the prevailing strike of the country. 

 This outcrop is interesting as being on the most easterl}^ scarps of 

 the hill country overlooking the plains of the River Murray. 



Mount Remarkable is the most prominent elevation of the 

 southern Flinders' Ranges, over 3,000 feet in height, and rises 

 abruptly from the plains which extend for many miles on its eastern 

 side. The Mount is a well-defined horst, as it is circumscribed by 

 important faults on all sides accompanied by wide zones of brecciated 

 fault-crush rock. The main mass of the Mount consists of quartzite, 

 but on its western side the Cambrian glacial till makes an important 

 feature. At the northern end of the Mount the glacial beds are cut
