“ CLIMBING ALONE, WITHOUT A COMPANION, IS NOT PERMITTED.
The climbing season varies with the weather and the amount of snow in the range; it is at its best during July, August, and early September. In most cases it is advisable to allow 2 days for an ascent of Grand Teton, Mount Moran, or Mount Owen and 1 day for other major peaks. Jenny Lake Campground is the logical outfitting point for most expeditions. The majority of ascents require ice axes, rope, and hobbed boots or climbing shoes. Guided parties may arrange to rent equipment from the guide. ”

“ Preservation of Natural Features and Public Buildings—Trees, flowers, vegetation, rocks, minerals, animals, or birds may not be disturbed, injured, or destroyed, and buildings, signs, or equipment may not be defaced or destroyed. No material of any kind may be taken from the park without a written permit from the superintendent. ”

“ Persons inexperienced in mountain climbing are requested to obtain the services of a mountain-climbing guide, 12 or attempt climbs only when accompanied by experienced climbers. Since 1931, authorized non-Government guide service has been available in the park. In view of the difficulties one encounters on the Teton peaks and the hazards they present, all prospective climbers are urged to make use of the guide service. If venturing out unguided, climbers should consult rangers or guides for full information relating to routes and equipment. ”

“ Mountain Climbing—All mountain climbers must register at the ranger stations before starting to ascend any peak and must report their return from each climbing expedition. SOLO CLIMBS ARE NOT PERMITTED.
Automobiles—Drive carefully at all times. Speed limits are posted; these vary for different sections of the park. All accidents should be reported at the nearest ranger station. Fees for automobiles, trailers, and motorcycles are collected at the park entrances. All fees are deposited in the United States Treasury and are not available for expenditure in the park. ”

“ The moose, largest member of the deer family, is not as wary as other deer. Mule deer are increasing in the park and environs, and, though quite shy, are often seen along the trails by hikers and horseback riders. ”

“ Campfire permits are required for fires to be built in any place other than the regularly designated campgrounds.
Guide Service—At Jenny Lake there is an authorized official mountain-climbing guide who will guide climbing parties to the summits of the major peaks. He gives instructions in mountain climbing at frequent intervals during the climbing season.
Information concerning rates for all climbs may be obtained from the superintendent of the park or from the mountain-climbing guide. ”

“ Saddle Horses—The park saddle horse concessioner maintains an excellent string of saddle and pack horses, with good equipment for short or long trips. Saddle horses may be rented without guides, but only to ride over well-defined trails in designated areas. ”

“ The superintendent is the representative of the National Park Service in immediate charge of the park, with offices at park headquarters. All communications regarding the park should be addressed to the Superintendent, Grand Teton National Park, Moose, Wyo.
Rangers and ranger naturalists are stationed at various locations in the park to assist in the protection of the area and to help visitors to enjoy the park and understand its natural phenomena. ”
