404 Wood — Effects in Mohuaweoweo of the Eruption of 191Jf. 



by numerous, roughly circular, down-faulted areas, only a few 



feet (say two to three meters) in depth, with overhanging 



margins. These range in size from ten feet (about 3 meters) 



to, say, about 300 feet (or about 100 meters) in diameter ; the 



larger are less regular, but even these approximate to the 



circular outline. 



?£ This whole field of new lava is much fissured but, except as 



noted, the fissures have a wholly irregular arrangement, and 



distribution. 



\\\ Through this field the cones were approached along a series 



of leads or irregular lanes, which involved very little going

except on pahoehoe. Only a few zigzag crossings over strips of 

 a-a, or fissure zones, were necessary. The appearance of these 

 cones viewed obliquely from a distance of a half-mile, or so, is 

 seen in the photograph fig. 10. In this they are shadowed 

 by a cloud in early afternoon, which thus affords a bold 

 silhouette of them. 



Just before these cones are reached from the north, we come 

 to the edge of the new lava of 1914-15 and then pass across a 

 small field of older pahoehoe (1903) characterized by a surface 

 of miniature flow tubes. Some of this lava had a pumiceous 

 surface, In a short distance this becomes covered by fallen 

 clinkers and pumice, first from the cone of 1903, and later 

 from the cones of 1914 also. 



The surrounding of the 1903 cone have been described 

 already. The photograph fig. 11 is a view looking about S.W. 

 from the summit of a small cone (1914) just east of that of 1903.
