stanton.] MALONE MOUNTAIN AND THE JURASSIC. 25 
also described a the succession of strata in the middle section of the 
mountain, which agree in the main with my observations, though 
both structure and exposures vary greatly in different parts of the 
uplift. 
The most complete section that I observed, in which the thicknesses 
were estimated with some care, extends across the mountain from a 
point on the east side about one-half mile south of Malone station. 
The eastern face of the mountain shows an apparent thickness of 
about 1,200 feet of blue and gray limestones, with a few inter- 
calated beds and bands of conglomerate and sandstone, the beds all 
dipping strongly westward with increasing dips until they become 
vertical on the crest. On the Avest slope there is a succession of lime- 
stones, conglomerates, and gypsum beds, nearly vertical and not well 
exposed, and farther down these are apparently repeated with a 
westerly dip, overlain by conglomerates, limestones, etc., fairly well 
exposed and not much disturbed in the lower ridges to the west. 
The gypsum beds and the limestones immediately associated with 
them appear to be the oldest rocks exposed. The following section 
begins with what was supposed to be the lowest gypsum bed, but on 
account of complex structure and obscure exposures the succession 
and thickness of the first five members are somewhat uncertain.
