 coloured and purple or brownish 

 sandstones, very obliquely laminated 

 and containing highly silieions beds, 

 which, either sharply contorted or 

 dipping at high angles to the north, 

 form the low outer ridge on the 

 north side of the range. 



The obhque lamination in some 

 of these coarse beds 

 is at times so exces- 

 sive as to assume an 

 •s appearance of unconformity, which 

 I is, however, only local, and the beds 

 I sometimes contain small bright red 

 S jasper-like fragments. It is hardly 

 ■g safe to trust to appearances of thick- 

 3 ness among these contorted rocks, 

 g but in one place they were seen 

 i with a dip of 50° to 80° to the 

 I north, showing a steady thickness 

 i of 250 feet, which can be but a 

 E small part of that required to account 

 for the portion of the series formiuCT
