Six beds of coal, ranging from 1 foot 3 inches to 2 feet 10 inches, 
were found in a zone 275 feet thick, the lowest coal occurring 95 feet 
above the top of the Mancos shale. From the Utah-Colorado bound- 
ary to some miles west of Thompsons a bench about 100 feet in 
height and half a mile to a mile in width, caused by a thick lens of 
sandstone in the shale, extends along the base of the cliffs, and the 
coal outcrop therefore lies farther back in the cliffs than usual. 
Near Harms's ranch (No. 28), at the mouth of Cottonwood Canyon, 
there is a bed of coal 1 foot 6 inches thick. Mr. Harms reports bods 
varying in thickness from 2 inches to 3 feet, but says that flu 4 coal 
contains much bone and is of poor quality. 
About a mile and a half above Nash's ranch (No. 29), in a canyon, 
two beds of coal were observed, separated by an interval of about 60 
feet. The lower bed is 1 foot 10 inches thick and occurs 350 feet 
above the top of the Mancos shale; the higher bed measures 4 feet 8 
inches, but little attempt has been made to develop it. 
More work has been done on the coal north of Thompsons than any- 
where else in Utah in the area covered by this report, although the 
prospecting even in this locality has not been thorough. Several 
beds of coal are present. The following seel ion shows five beds more 
than 2\ feet thick within 125 feet of strata:
