Shelter is not available in some of the most beautiful sections of the park. To those who are sufficiently sturdy to pack blankets, cooking utensils, and provisions, and are sufficiently versed in woodcraft to take care of themselves overnight, Glacier presents wonderful opportunities. Provisions can be purchased at Glacier Park Station, Belton, and at any hotel or chalet in the park. For fire prevention, it is unlawful to build campfires (or fires of any kind) except at designated places. The location of these sites can be ascertained from park rangers. Unless one is an experienced mountaineer and thoroughly familiar with the park, it is unwise to go far from the regular trails alone. He should not scorn the services of a guide on such trips. _Above all, he should not attempt to hike across country from one trail to another._ The many sheer cliffs make this extremely dangerous. If one is a veteran mountaineer and plans to climb peaks or explore trackless country, he should take the precaution to leave an outline of his plans at his hotel, chalet, or camp, giving especially the time he expects to return or reach his next stopping place. At each ranger station, hotel, chalet, and permanent camp in the park will be found a "Hiker's Register" book. Everyone is urged for his own protection to make use of these registers, entering briefly his name, home address, time of departure, plans, and probability of taking side trips or of changing plans. The hotel clerk should be informed of these at the time of departure. If a ranger is not there, this information should be entered in the register which will be found near the door outside the building, so that when the ranger returns he can report it to the next station or to headquarters. These precautions are to protect the park visitor. In case of injury or loss, rangers will immediately investigate. In planning hiking trips, the following should also be taken into consideration: At higher elevations one sunburns easily and painfully because of the rarity of the atmosphere and intense brightness of the sun. Hikers should include in their kits amber goggles and cold cream for glacier and high mountain trips.
