nearly the whole space to the south; of Pelado between the San 
Diego canyon and Vallecieto creek, nearly as far south as 
Jemez. There is another small patch to the southeast of Valle- 
cieto creek south of Vallecieto Vie jo. 1600 feet of Red Beds 
strata are exposed here in vertical section in several places but 
as the strata dip at a considerable angle toward the southeast, 
their true thickness must be less. 
Another area appears to the south of Canyon Honda east 
of Jemez with strata dipping east at an angle of 45". Only a 
narrow ridge now remains of these beds at this point. A 
patch is exposed several miles southeast of Cabizon, but the 
writer knows little of it. The last Red Bed patches of this 
region occur as outcrops along a spur of the San Dias which 
extends in a northeast direction, one patch being just to the 
west, another just to the east of Tejon. The strata of these 
beds are brought to the surface by faulting. The west patch 
is underlaid by the Permian and Carboniferous with which it 
seems to be conformable. The Carboniferous here mentioned 
is the small area east of the Rio Grande near Tejon, mentioned 
in the Carboniferous discussion. These Red Beds dip east at 
an angle of 45°. They differ from the other Red Beds, above 
mentioned, in that they are capped with forty feet of cherty 
vesicular limestone on the top of which are about a hundred 
feet of light colored sandstones which in turn are covered with 
a yellow limestone cap. The aggregate thickness exposed is 
about 500 feet. Some have called the lower strata "Trias" and 
the upper Cretaceous^ ; others have called the whole Juratrias. 
But it is the opinion of the writer that they all belong to the Red 
Beds series, since the strata, as a whole, seem to be conformable 
with the underlying Permian and Carboniferous. It is quite 
possible that this area was not broken up and raised above the 
sea till after the Jemez Red Beds had been made land. This 
would account for the lime and sand deposits being conform- 
able with the Red Beds below in the same series. They are not 
Cretaceous because they are conformable with the Red Beds and 
Cretaceous at no place where observed is conformable with 
these rocks. As further evidence that these limestones and 
sandstones are not Cretaceous, the gypsum rests upon them to 
the east, separating them from the Cretaceous. This gypsum 
is the same in structure and appearance as that visited in the
