are steep, with abun- 
dant ledges, and in 
some cases the gorge 
walls steepen as they 
descend to the stream 
line. The slopes of 
the spur profiles com- 
monly steepen toward 
the front base line; 
their general descent 
is at angles of from 10° 
to 25° ; but they often 
steepen downwards to 
30° or 35°. The spur 
terminals are, however, 
well rounded, and but 
faintly recall the sharp- 
edged facets of the 
Spanish Wahsatch. 
The southern part 
of the Pueblo range 
offered the best illus- 
trations that I found 
of the trailing end of 
a faulted block, less 
dissected than the mid- 
dle part and therefore 
probably representing 
a subrecent increase in 
the length of the block 
by a southward exten- 
sion of its marginal 
fault. The front base 
of the range is here as 
elsewhere oblique to 
the structure ; the crys- 
talline rocks disappear 
first, and the lava mon- 
ocline continues sev- 
eral miles further south
