MOUNT GREYLOCK. 135 



farther into the mountain, while on the west, across its mouth, lies Deer hill. 

 (Compare Pis. xm and xvn with the map, PI i.) The portion of the western 

 face south of these great spurs is best seen from the north end of East 

 mountain or from the north end of Sugarloaf mountain in New Ashford. 

 This shows (PI. xiv), a few hundred feet below and parallel to the central 

 crest, a very regular, horizontal bench over a mile in length, below which 

 is a steep declivity followed by a far wider and longer bench of more or 

 less open pasture land. (See also Fig. 74, p. 194.) Below this again the 

 base of the mountain is deeply cut into by a series of east and west ravines 

 parallel to the Hopper. The northern one of these is known as Goodell 

 hollow. 



The aspect of the Greylock mass on the south (PI. xv) from the 

 north end of the Lenox mountain range (known in Pittsfield as South moun- 

 tain), which is about 15 miles south of the Greylock summit, shows the pe- 

 culiar saddle shape of the higher portions of the mass which render the 

 name of Saddle mountain so appropriate, and so familiar throughout south- 

 ern Berkshire Greylock summit (3,505 feet) and Saddle Ball (3,300 feet), 

 about 2 miles apart, form the two humps of the saddle, while the inter- 

 vening portion of the crest with a southwesterly bend descending to the 

 2,900 feet contour forms its seat. This corresponds to internal stuctural 

 features. This aspect also shows the subordinate ridges and spurs on either 

 side of the mass as well as the benches on either side of its higher portions. 



The aspect of Greylock from Clarksburg mountain on the north shows 

 the central ridge with two lateral and lower ridges: that on the east — Rag- 

 ged mountain — separated from Greylock proper by the Notch; that on the 

 west, forming Mount Prospect and Bald mountain, separated from the cen- 

 ter by a minor saddle, hence long ago also called Saddle mountain, which 

 farther south passes into the north-south gorge continuous with the Hopper. 

 From the Coast Survey station on Mount Equinox in Vermont, which is about 

 35 miles north northwest, and therefore at an acute angle to the strike 

 of Greylock, the saddle form of the central crest appears much broader 

 (Fig. 30). On the east of it the top of Ragged mountain is seen, and on the 

 west several of the subordinate masses. 1 The structural significance of these
