Still nearer the summit and on the right side of Coverdale, a little 
stream, descending from a surface of pebbly and flaggy grits, and shales, 
(five hundred feet below Great Whernside) exposes the following beds ;

South-eastern limits of the Yoredale Series .— Comparing these sections 
in Coverdale with those formerly given in the adjacent parts of Ivettle- 
well dale, (pp. 30, 31,) it will be seen that both the main lime and under- 
set lime (together making the Cam group) become gradually but com- 
pletely extinguished on the west front of Great Whernside ; not because 
of any dislocation, but as a law of their original deposition. These lime- 
stones have no existence farther to the south-east than the line indicated 
(p. 19,) as the southern boundary of the Yoredale series. It will also 
be seen that the gritstones, and plates, and coal, which essentially charac- 
terize the Yoredale series, terminate almost completely on the same 
boundary line as the Cam group ; and comparison of the sections of Great 
Whernside, Parkhead, Starbottom, and Bishopdale head given in pp.
