Figure 6. — The three main craters as seen from the ridge to the south. The inconspicuous rim of the 

 largest crater (no. 7) extends from the left edge of the photograph almost to its right edge. Crater 6, 

 the water crater, is conspicuous because of the large number of trees growing within it. Crater 8 is 

 to its right. 



Figure 7. — Interior of the largest crater (no. 7), looking north from its southeast rim. The gentle slope 

 of its walls shows considerable erosion. The walls rise approximately 50 feet above the floor. 



Figure 8. — Floor of crater 6, the water crater, consisting at the time of the photograph of a flat, drj- 

 mud area serrated by cattle footprints. This photograph looks east from the floor toward the common 

 rim of craters 6 and 8.
