HUNTER PARK SPECIAL MAP. NAY 
apparently isolated hill a little to the right of the center of the picture is in 
the zone which lies between the granite and the red beds. At the base of 
the hill to the right the granite outcrops; higher up is the Cambrian, and 
at the top of the hill is the Silurian dolomite, while in the peculiar gap 
comes in the Silver fault, and to the left of that the Weber shales. The 
shaft dimly shown in the gulch at the left of the hill is the Badger, which 
has gone down through the shales to the contact of shale and dolomite at 
the Silver fault. In outline against the sky at the left of the picture is 
shown a peculiarly rounded hill. The base of this hill, as seen in silhouette 
where it meets the slight westerly dipping slope on the east side, is about 
at the contact of Weber and Maroon. The hill, therefore, occupies the base 
of the Maroon formation with its alternating thin beds of calcareous sand- 
stone and arenaceous limestone with intercalated shales. These strata dip 
to the west, or toward the left of the plate, and a peculiar and striking 
feature in the landscape is that the slight amount of vegetation, consisting 
chiefly of bushes and aspen trees, which has accumulated on the side of 
this hill, has arranged itself in symmetrical bands indicating the position of 
the outcropping strata. The reason for this appears to be that in the more 
porous beds there is a greater amount of moisture, and that the vegetation 
along this zone becomes more thrifty, or that the limy beds furnish more 
nutrition to plant life than the more arenaceous ones. This banding is best 
shown in autumn, when the frost gives the aspens their most brilliant 
coloring. 
FOLDING. 
In the northeast part of the district the broad outcrops of Cambrian 
and Silurian indicate a flattening of the strata to the east, corresponding to 
the fold which has been described in the canyon at Lenado. West of this 
flattening, as at Lenado, the beds become steeper, and in a short distance 
the dip becomes uniform, and so continues to the western edge of the dis- 
trict. This flattening of the strata to the east is not shown in the central 
and southern parts of the district, for here erosion has removed the upper 
part of the fold, leaving only the steeply dipping beds below. Through 
the whole section west of the granite, in these portions of the district, the 
uniform dip to the west is probably about 45 degrees, being less in some 
places and greater in others.
