PLATE 2A. Northwest wall of Kilauea Crater seen from near Keanakakoi. The Uwekahuna tuff formerly 
was exposed at A, and at present is exposed at C and S. The rim block containing A has slumped a greater 
amount from its original elevation than has the rim block containing C and S. Photograph by H. A. Powers, 
September, 1947. 
Plate 2B. Bedded Uwekahuna tuff at locality A buried by the 1919 pahoehoe flow on the crater floor 
which filled against the cliff as high as the dashed line. Vertical solid line indicates the span of a 13-foot sur¬ 
veyor’s rod located against points of the cliff face which have not changed since the photograph was taken by 
T. A. Jaggar, July, 1913. 
PLATE 2C. Uwekahuna tuff, 314 feet deep, lying on the basal pahoehoe flow exposed in the cliff at S. Base 
of tuff is 5 feet above the present crater floor. Inter-eruption surfaces have been spotted on the negative.
