210 McGee and Call— Loss of Dee M<m 



N. side Center St. bet. "W. 1th and W. 8th Sts.— Alt. 877 ± 2 ft. 



1. — Brownish-yellow <1 ri ft clay containing rounded, sub-ai <_rnlai 

 and angular pebbles, mainly erratic, up to ten inches in 

 diameter, ami 1 discontinuous 



lines of stratification, together with loss-kindchen and tube- 

 lets, below ; where it passes by both interstratification and 

 insensible gradation into loss. Above it is finer, less pebbly 

 and more homogeneous. 



2. — Loss, light buff, with a few irregular and tortuous lines of clay, 

 sand or gravel intercalated above, but undisturbed and in 

 all respects typical below, where it contains abundant 

 tubelets, rather few and small I"»s-kindelien,and rare fossils 

 of the following species : 



Succinea obliqua Sar. 



The cutting (which was not fresh at the time of exam 

 is nine feet deep; its summit being approximately level for 

 half a block. The line of junction of 1 and 2 slopes west, ex- 

 posing only the loss at the middle of the block, and only drift 

 at the northeast corner of Center and Seventh streets. The 

 drifl has manifestly been removed by erosion toward the east. 

 Within half a block to the north the superficially modified 

 drift has been removed to a depth of two feet from a consider- 

 able area, exposing some dozen crystalline bowlders up to three 

 feet in diameter; one, of green stone, being polished. Over 

 this area, as in the loss of the section, there is a profuse cal- 

 careous efflorescence. 



- is.— Altitude 970 ±12 feet. 

 [•teen feet deep, only drift is exposed. 

 It is rather fine, clean and homogeneous for the first three feet, 

 then abounds in pebbles of stone with a few of sand for eight 

 feet, and toward the base exposes mainly sand, pebbles associ- 

 ated with small stone pebbles, loss-kindchen, tubelets, and rare 

 fossils; but these phases graduate into each other — there being 

 not the slightest trace of stratification from bottom to top. 

 The stone pebbles vary in size from ten inches downward, are 

 mainly erratic, though a few, including bits of coal, are local, are 

 generally round or sub-angular, and are occasionally smoothed 

 and polished. One, two inches in diameter, is finely striated on 

 both sides ; the two sets of stria} on one side diverging by 30° 

 and 60° respectively from the single set on the other side. To 

 another, a calcareous concretion is attached. Most of the sand 

 pebbles (of which a score or more appear in the sides and bot-
