Rocky fountain Trip 
from south Aba jo to Ute mountain, parallel with the above men¬ 
tioned depression. South of this there is a gentle dip to the 
San Juan. Beyond the plains east and southeast appear Lone Cone, 
Sierras, San Miguel and LaPlata and Matel, south the Cariso and

Tunecha, Mesa Verde and Needles, and far off to the west the arched 
outline of Hough mountain and the mirage like MonumentalVailey• 
Down what appeared to be the line or course of Lpsom Creek appears 
a long straight line of white sandstone outcropping under or west 
of Ho. 1 and rising to the west over a scries of red and gray 
sandstones. The western line of Ho.l is south from the middle 
of the Aba jo group along the divide between Lpsom Creek said the 
drainage to the east, which is partly Hontezuman and below into 
Recovery Creek. As to the Aba jo group itself there is but lit¬ 
tle can be said - its geology aid geologic history seem the sim¬ 
plest possible. A mass of trachyte (or perhaps masses of trachyte) 
» 
has been pushed up through the sedimentary strata, turning up the 
edges here and there and resting in great masses in or on the 
cretaceous shales (chiefly). On the east face No. 1 ispturned 
up in a little hog back which dips 45° 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 No. 1 could be traced around to the north, not 
appearing about south Aba Jo peak on the north or 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 trachytic hills
