Fig. 2. Generalized pattern of distribution of several eruption deposits, shown at one-half the scale used 
in Figure 1. A, reticulite from eruption 1-K; B, composite vitric deposits from eruptions 3-K to 9-K, inclu¬ 
sive; C, vitric deposits from eruption 13-K; D, lithic deposits from eruption 15-K; E, lithic deposits from 
eruption 17-K; F, lithic deposits from the 1790 eruption. 
Uwekahuna tuff, has an altitude of about 3,920 
feet, indicating that the tuff lies beneath nearly 
300 feet of bedded lava flows in the wall of the 
present crater, rather than the 170 feet sug¬ 
gested by Powers’ sentence. 
The most extensive occurrence of the Uwe¬ 
kahuna tuff is an apparently continuous, nearly 
horizontal deposit extending for about 5,000 
feet (between localities B and C in Fig. 1 and 
Plate 3A), interbedded in the lavas of the 
northwest wall of Kilauea crater, and exposed 
in outcrops between talus fans at the base
