Once the big-game population was numerous. But the grizzly has been almost exterminated, and only a few black bear remain. There are a few mountain lions and elk. Deer are fairly common, and in localities mountain sheep are plentiful and on the increase. Specimen Mountain probably is one of the places most frequented by mountain sheep. A number of times flocks of more than a hundred have been seen on this mountain. A scattering of wolves, coyotes, and foxes remain. Conies are numerous in the slide rock of the heights, and snowshoe rabbits people the forests. The Frémont, or pine, squirrels are scattered throughout the woods. Lunch where you will, and the dear and confiding busy chipmunk is pretty certain to approach. The region appears to be above the snake line, and I have never seen a snake within the boundary. The streams and a number of the lakes have their population of rainbow and brook trout. Around the water's edge mink make their home.
The beaver has colonies large and small all over the park up to the limits of tree-growth. Houses, ponds, dams, tree-cuttings, canals, and other works of the beaver are here readily seen. Excellent opportunities are afforded to study beaver manners and customs and to comprehend the influence of his work in the conservation of soil and water.
Big game, and in fact all wild life, begin to increase in numbers and also to allow themselves to be seen from the instant they receive the complete protection which parks afford. This park will thus assure a multiplication of the various kinds of wild life which the region now contains. And this increased wild life, with no hunters to alarm, will allow itself to be readily seen.
There are only a few miles of road within the Park boundaries, but the Fall River Road, now under construction across the Continental Divide at Milner Pass, just south of Specimen Mountain, will be a wonderful scenic highway. Although there are a number of trails in the Park, so broken is the topography that most of the country a stone's throw away from them is unvisited and unknown.
A road skirts the western boundary of the Park and touches it at Grand Lake and Specimen Mountain. Another road closely parallels the eastern boundary-line, and from it a half-dozen roads touch the Park. This parallel road reaches the roads of Denver and of the plains through the Boulder, Left Hand, Big Thompson, and two St. Vrain cañons.
The drainage of the western half of the Park concentrates in the Grand River on the western boundary and reaches the Pacific Ocean through the Grand Cañon of Arizona. A number of streams rise in the eastern side. These assemble their waters in the Platte River out on the plains. In their upper course, all these streams start from the snows and come rushing and bounding down the roughest, steepest slopes.
The climate of the eastern slope is comparatively dry and mild. The winters are sunny, but little snow falls, and the winds are occasionally warm and usually extremely dry. Though only a few miles from the eastern slope, the western rarely receives a wind, and its snow-fall is more than double that of the eastern.
