eastern end the block surface passes beneath the cover. A 

 small portion, like the neighboring cover, is here maturely dis- 

 sected. 



On the southeastern side a very regular and apparently 

 simple fault scarp about 20 miles in length, with an average 

 height of 3,700 feet, descends from the even crest to a long, 

 narrow fault-angle depression named the Strath Taieri, fol- 

 lowed longitudinally by the Taieri River. Its planed floor, 

 beneath which is preserved a narrow strip of the overmass.

 Pillar Range is on the right, and the Lammermoor and Lamraerlaw Ranges 

 are seen in the distance, their fronts being the scarp of a high plateau. 



descends from about 1,000 feet above the sea at the northern 

 end to about 600 feet at the southern end. 



On the southeastern side of the Strath Taieri depression the 

 surface of the stripped undermass rises very gently to a 

 plateau (flg. 16) varying in height from about 1,000 feet to 

 2,000 feet above sea-level. The plateau is traversed by a num- 

 ber of low, southeastward-facing fault scarps (fig. 17). In the 

 fault angles some strips of cover are preserved and there are 

 also lava-capped remnants on the uplands. This area with 

 that to the southwest has been called by Park the Barewood 

 Plateau. Its southwestern continuation is bounded on the 

 western side by the fault-scarp margin of a higher plateau 

 area practically continuous with the top of the Rock and 

 Pillar block, though at a slightly lower level. This is the 

 same broken plateau into which merge all the upland and low- 

 land blocks enumerated. The conspicuous 2,000- feet fault 

 scarps along the boundary between the higher plateau and 

 Barewood plateau have caused portions to be known as the 

 Lammermoor and Lammerlaw ranges.
