hood of the abandoned "A L Ranch " on the Rio Grande west of 
Quitman Mountains, in the small triangular area bounded by the 
liver and the Eagle Mountain and Fort Hancock quadrangles. The 
Fredericksburg beds are especially well exposed about 2 miles down 
the river from the ranch, in the small canyon locally known as the 
Cajoncito." The next prominent ridge, 3 or 4 miles to the east, 
shows Washita shales and limestones, with intervening dark shales 
that may belong to the Upper Cretaceous. 
These details of the stratigraphy and distribution of the Cretaceous 
in this region are given for the purpose of emphasizing the peculiar- 
ities and the isolation of the Malone beds.
