GEOGRAPHICAL AND GEOLOGICAL OBSERVATIONS
The position of the mountain. as l showed above,
is such to make it admirable post of geograrh-
ica observation, especially regards the relations
of the National range to the mountains on either
side On the east is seen the fine serrsted series of
bare rocky peaks that border the Blue River; pass
ing, further south, as the sedimentary rocks gain
more and more the upper hand, into the more
rounded SUBMITS of the Mount Lincoln range
continuation of the same general line of uplift On
tho west, the remarkable mountains of which the
White House and Capitol arc the dom
mating peaks, fill the horizon, and the point
of view is sufficiently outside the line of the Ma
tiona range itself to let most of its principal sum-
mits be clearly made out. Nearly threequarters OF
the whole sphere of vision is thus crowded with
mountain masses; only toward the norththe country
spreads out into rolling plains and plateaus which
lead the way to the regions cut by the Colorado and
its tributaries. AS mountain view this is MOI
markedly different from some OF those we nave al
ready enjoyed has it any superior beauties that
would repay the tourist for the superior hardshlps
OF its ascent.
