(50) 100 yds to the east the 8,9 and maybe the 7 beds are gouged out & and a chert quartzite Conglo fills a 40 to 45' depth channel. I take this to be an old river channel. It has the appearance of the typical meandering conglo of the western party, the later. This channel is about 130 yds wide in outcrops. (12) Dolostone, Brown weathering, 6" to 1' beds, Locality the Beds on small road Ese. 36' 5/19/57/13 (13) Sandstone; light brown to tan weathering. grease of chert+quartzite conglo pebbles. 3'-1'-beds, 6' (14) Conglo; 5" cobbles, mainly very limited, with sandstone lines of it's mostly chert + quartzite near base, seems to be near top ; 16'; This is like conglom erate channel; little no. 6s formed part. (15) Covered, 15' red soil. (31) (16) Conglo; mostly dark gray & light gravelly; sandy clay matrix as well. (mostly a pebble conglo.) 2' (17) Covered, 15', red soil. (18) Calcarenite, chalky tan weathering, 2' to 8' beds, 3'; 12" Cobbles (19) Covered, Red soil, 12' (20) Calcarenite; 5', 10" Cobbles, light to tan/gray, no cobbles. Top of Beds found Conglomerate I named draw the top of the Waycamp (based on Geology) at the top of the Calcostone unit, and the base of the waycamp at the base of unit 7. The 2' conglo (#15) is dead to claim but it seemed to have only ls of the 8 & 9 types in it. The rest of the conglom has a great deal of chert. W E not is pebbles, except main edges
