Introduction. 
THE district around Toquerville, in the southwestern corner of Utah, 
is one which offers much for geological study. In a recent number of 
this Bulletin Professor W. M. Davis of Harvard University calls atten- 
tion to the problems seen at Toquerville, more particularly to those 
which concern the northward extension and the disputed age of the 
great Hurricane fault (b, p. 147). A closer acquaintance with these 
problems was made when, in the summer of 1902, the writers had the 
opportunity to visit the Toquerville district under the guidance of Pro- 
fessor Davis, and to spend a few weeks there in geological field work.
