the flattening noted. The location of this second anomaly correlates with 

 the position of the Kettleman middle dome, as also appears from the 

 structural contours in Figure 261. The flattening in the gravity contours 

 reflects the saddle hetween the two domes.

 tours in Kettleman Hills Area (north of Kings-Kern County line) after Uren (California Div. 

 of Mines, Bull. 118, Part One, p. 45), contour interval 500 feet; in Lost Hills Area, on top of 

 Temblor, after Follansbee (California Div. of Mines, Bull. 118, Part Three, p. 495), contour 

 interval 1000 feet. {Geophysics, Vol. XI, No. 2, April, 1946, p. 125.) 



Continuing along the gravity ridge (from the second gravity anomaly) 

 the strike changes to a south direction, and the gradient again flattens 

 near the center of T. 25 S. R. 19 E. A third gravity anomaly (which is 

 similar to the second one) is expressed by a steep maximum gravity nosing.
