Kooky mountain Trip 
31 
from south Aba jo to Uto mountain, parallel with the above men¬ 
tioned depress Ion* South of this there is a gentle dip to the 
San Juan, Beyond the plains east and southeast appear Lone Gone, 
Sierras, Ban Algae1 and LaPlata and Latex, south the Uarise and 
Tuneeha, Mesa Iferde and Reedies, and far off to the west the arched 
outline of Rou^b mountain and the mirage like MonumentalValley* 
Down what'appeared to be the line or course of Epsom Creek appears 
a long straight lino of white sandstone outcropping under or west 
of Ho. X and rising to the west over a series of red and gray 
sandstones, The western line of No.l is south from the .middle 
of the Aba jo group along the divide between Epsom Creek and the 
drainage to the east, which is partly Montesuman and below into 
Recovery Creek. As to the Aha jo group itself, there is but lit¬ 
tle can be said - Its geology and geologic history seem the sim¬ 
plest possible* A i mm of trachyte (or perhaps masses of trachyte) 
has been pushed up through the sedimentary strata, turning up the 
edges here and there and resting ha great masses in or on the 
♦ 
cretaceous shales (chiefly). On the east face Bo * 1 is turned 
up in a little hog back which dips 43° for a short distance and 
then slopes off gently to Montezuma Canon 7 or 8 miles away* 
Inside of Ho. 1 and almost obscured by the slides or trachyte 
appears the purple shales of the Jurassic somewhat metamorphosed. 
The outcrops of Jurassic seemed to be confined, to the main east¬ 
ern spur, while Ho. 1 could be traced around to the north, not 
appearing about south Aba Jo peak on the north or 1 east but around 
the south and west and in the first valley heading west of our 
station and running south (see sketch book). The mountain group 
is not a solid mass but rather a collection of traohytic hills
