150 yards more, but after that, as far as I was able to go (about 
four miles measured along the coast, though much less as the 
crow flies) no more was visible 
The cliffs here, at the end of the Eocene, are of great height, 
but it is hard to say exactly what. The top of the escarpment 
is not well defined, and from there the ground slopes directly up 
to the Sellick's Ranges. Quite close to the cliff, though not right 
atits edge, I was at an elevation of a 180 feet. 
The Cambrian near here dips at an angle of 65° to 70° to the 
north, the westerly strike being very clearly shown by the bands 
ment. This reef protects the cliff from the sea 
projections, painful to walk on; and others, which present the 
most peculiar appearance, com of black  ferruginous 
dolomite, whic ears away along the lines of stratification 
does not appear on the face of the cliff, but is very plentiful on 
the shoreline, not only along here, but also right back to where 
the Cambrian first appears. Masses of ironstone are also to be 
met with occasionally. 
After the end of the Cambrian reef the cliffs are not nearly 8° 
back | at, with frequently a surface coating of clayey soil 
carrying vegetation. The rock itself, which crops out frequently, 
also becomes more calcareous in is, therefore, 
hard to obtain, as even where a fair section is shown there is no 
reef to show the strike, which is highly important with such à 
great dip. Occasionally, where the cliff slopes back more than 
with. Also, at intervals, there is a jutting point of rock extend- 
ing right up to the sea, making it difficult to pass, and this 
appeared to be more frequently the case towards Myponga.
