In addition to Wind Cave, Jewel Cave, and Ice Cave, there are a number of other caverns of varying interest and underground beauty which have been opened and exploited by private individuals. In many cases these are but indifferently arranged for public inspection, but can be tracked down by the visitor by means of the garish signs which too often manage to clutter the otherwise unblemished scenery. _Just Scenery_ The foregoing are only a very few of the scenic wonders of the Black Hills. Detailed information on the various other scenic features is easily to be had at any of the hotels and tourist courts in the Hills, and brochures covering practically every landmark are available gratis, thanks to the enthusiasm of the local chambers of commerce, the Black Hills and Badlands Association, and the state of South Dakota. The area is crisscrossed with good roads, and no matter which route one takes to his eventual destination, every mile will be marked by breath-taking views and natural wonders. The region, except at the summits of the peaks, lies at an average altitude of some five thousand feet. Cool nights are thus guaranteed, regardless of the temperatures by day. The highest mean temperature ranges, during the six months between April and November, from 60 to 85 degrees. Light outing clothes are suggested for day wear, and light wraps are always in order after dark. The rainfall during this same six-month period, averaged over fifty years, amounts to three inches per month; what small showers do occur take place most usually in an hour or so of the early afternoon, and refresh rather than hinder the tourist. The hillsides are covered with a mass of shrub and tree growth, and an earnest searcher can find specimens of no less than fifty-two varieties. Yellow pine, spruce, cedar, ash, aspen, alder, dogwood, and cottonwood are most in evidence. The bird lover will find the Black Hills nothing less than a vast aviary, more than two hundred species having been seen in the region. Animal life is almost as widely represented, although the casual visitor is not likely to come upon a native mountain lion or gray wolf. The assistance of forest rangers and Park Service employees is available in locating the habitats of some of the rarer varieties of wildlife. As might be expected, the fisherman will find plenty of opportunity to ply his pole in this region. There are nearly 150 miles of stream and lake frontage in the Black Hills, and the waters are liberally stocked by the state hatcheries. In addition to trout, the angler will encounter pike, pickerel, bluegills, black bass, and perch.
