NORTH AMERICA AND THEIR VERTEBRATE FAUNA. 35 



Section g. — Northwest comer of Archer County (Gordon). 



" Outcrops of limestone are found on the boundary between Archer and Baylor 

 Counties. Some beds of the limestone at the top of the escarpment on the west side of 

 Horseshoe Lake. The limestone is earthy, dark blue, and weathers to a dark bro^vn or 

 black. The limestone is underlain by 4 feet of blue clay, and this by 100 feet of red con- 

 cretion-bearing clay, with a limited develoiomcnt of red and white limestone. From this 

 comer west the stratification is more rcgrdar; blue shales alternating with predominant red, 

 and an occasional bed of impure limestone."
