were hiding in the cotton jnrood groves below. The valley, 
at the mouth of which the mules were recovered seems probably 
to have been the one ascdnded by Capt. HcCorrib in 1860. A 
trail follows it 6 miles to its source thence to the northward 
across the sage mesa. a ^ 
No. 1 cretaceous, as usual, caps all the isolated buttes 
and mesa fragments North and South of the- river and covers 
the broad mesas that lie farther back. Between the branches 
of Recapture Gulch and in a butte to the West# No. 1'remains 
100 to 140 feet in thickness of the 'lower part - from 20 to 
60 feet is a massive conglomerate- made of principally of 
quartzose pebbles averaging perhaps the size of partridge egg. 
Nearly all of the lower country -from which No. 1 has been 
eroded- has a covering of these pebbles- the result of the 
disintegration of the conglomerate. The upioer part of No. 1 
is of massive rather soft yellowish sandstone. About 1000 
feet of strata beneath No. 1 forms quite a remarkable group. 
It is quite impossible -from any evidence here to identify 
them- to say whether they are jurassie, frlassie or carbonif, 
or partly of each. The upper parts for 200 to 400 feet cor- 
i 
respond very closely to the so-called jurassie marls, being 
a series of variegated clays and sand bedded with seams of 
hard gnarly quartzite and impure sandstones, also in the 
lower part considerable soft sandstone. Beneath the series 
of marls and etc., are some 800 feet of strata, mostly of
