CATSKILL FORMATION. G 5 . 67 



most of Wayne county. At Honesdale in Wayne county it 

 is well exposed and easily divisible. 



At Montrose in Susquehanna county, this group of rocks 

 forms the high band near the Fair Grounds, but no division 

 can be made.* 



Honesdale white sandstone (8), 25' thick. — This upper 

 member of the group is so nearly white in comparison with 

 all the other Catskill strata that its outcrop can be seen from 

 a distance passing from hill to hill over the country. It is 

 often current-bedded, and towards Pike becomes a regular 

 conglomerate. In spite of the whiteness of its weathered 

 surfaces, it is really when freshly broken dark-colored, 

 or rather of a grayish-brown, owing to numerous specks of 

 peroxide of iron. When these are weathered out the sur- 

 face is left grayish-white. One of its good exposures is the 

 long line of cliffs near J. Burn's, a mile south of Honesdale. 

 Many others will be mentioned in the township report. 



Honesdale red; sandstone (9), 40' thick. — This middle mem- 

 ber of the group is unique in one respect ; it is the only red 

 sandstone in No. IX, the other red rocks being all shales. 

 Its color however is light-red, showing that the specks of 

 peroxide of iron are much more numerous than in the rock 

 above. The stone is quite hard, fine-grained, usually thinly 

 laminated, and often contains a good deal of argillaceous 

 matter. Many rounded blocks of it are scattered through 

 the Drift deposits. — The Irvine cliff opposite Honesdale is 

 capped by these red rocks. 



Honesdale gray sandstone (10,) usually 25' but sometimes 

 50' thick. This lower division of the group is a series of 

 quite massive, gray, usually current-bedded layers, forming 

 the two miles of cliffs along the Dyeberry above Honesdale. 



Irvine's cliff, opposite Honesdale, is 300' high and nearly 

 vertical to the bank of the Lackawaxen. — No pebbles were 



*Montrose sandstones is a term which I have freely employed in my town- 

 ship reports, uncertain how much of the section in the hilltops around Mon- 

 trose (over the red-shale) ought to be restricted to the Honesdale sandstone 

 group. Vanuxem in 1844 applied the term Montrose Sandstone (Oneonta) 

 to distinguish one division of his Catskill, but seems to have looked upon it as 

 the lowest division of the formation ; whereas I find 500' of Catskill measures 

 still beneath drainage level at Montrose.
