Bridger Wilderness Bridger-Teton National Forest, Wind River Mountains About the Bridger Wilderness [Wilderness and You](#Wilderness Camping) Required Registration & Permits Wilderness Regulations Wilderness Safety [Allowed Uses](#Allowed Uses) About the Bridger Wilderness The 428,169-acre Bridger Wilderness is located along the Continental Divide on the west slope of the Wind River Range in Wyoming. It was designated a Primitive Area under Department of Agriculture Regulations in 1931, and later made part of the National Wilderness Preservation System with passage of the Wilderness Act in 1964. In 1984, its original 392,169 acres were increased by 36,000 acres when the Wyoming Wilderness Act was signed into law. The Bridger Wilderness is administered by the Pinedale Ranger District of the Bridger-Teton National Forest. Motorized vehicles and mechanized equipment, including snowmobiles, bicycles, hang gliders and chainsaws, are prohibited within the Bridger Wilderness. Wilderness, as defined by the Wilderness Act of 1964, is an area of undeveloped federally owned land, designated by Congress, that has the following characteristics: It is affected primarily by the forces of nature, where man is a visitor who does not remain. It may contain ecological, geological or other features of scientific, educational, scenic or historic value. It possesses outstanding opportunities for solitude and a primitive or unconfined type of recreation. It is an area large enough so that continued use will not change its unspoiled, natural condition. It provides the opportunity for (and often requires) self-reliance and challenge. Topography The intricately faulted Wind River Range is dominated by an igneous and metamorphic core. Enormous compressional forces in the earth thrust the block of granite into the air. The glaciation and erosion that followed carved the range, leaving 13,804 foot Gannet Peak the highest mountain in the Wilderness and in Wyoming. Glacial action left cirques, kettles, U-shaped valleys, hanging troughs, 1,300 lakes, and left "erratics", boulders strewn about the lowlands. The sedimentary rocks that once overlay the granitic core of the range have been stripped from the mountains by erosion. Remnants of the sedimentary rocks remain near Green River Lakes. The Wind River Mountain Range has seven of the ten largest glaciers remaining in the contiguous United States. The Green River originates in the Bridger Wilderness. The Green River joins the Colorado after 1,500 miles and empties into the Gulf of California. The Green River drains most of the west side of the Wind River Range. The Sweetwater River drains the southern end of the range and flows into the Platte River and ultimately the Gulf of Mexico. Access US Highway 191, the major highway between Rock Springs and Jackson, Wyoming, lies west of the Wind River Range. Trailheads are reached via roads which are clearly signed at intersections with Highway 191. Both Jackson and Rock Springs have commercial air and bus lines. Pinedale has a paved, non-commercial public airstrip located about 6 miles south of town. Shuttle services between Jackson and Rock Springs, and trailheads, are available from local private businesses. Trails There are over 600 miles of trails in the Bridger Wilderness. Most well-used trails are cleared early in the season, but fallen trees may be encountered on secondary trails. Winter snows generally do not leave the high passes and highest trails until mid-July. Stream flows are high and swift during snowmelt runoff in June and July, and some stream crossings can be hazardous. Check at the Pinedale Ranger Station Office, or call them at 307-367-4326, before beginning your Wilderness trip. Books with detailed trail descriptions are available at local sporting good stores and bookstores. Weather The weather is usually warm and sunny during the day from June through September, with afternoon thunderstorms being common. Night temperatures may be as low as 25 degrees Fahrenheit. Sudden rain and occasional snow flurries may occur at ANY TIME. During lightning storms it is best to avoid open areas such as meadows, ridges, lone trees, and mountain tops. Find safer shelter in dense stands of trees or boulder fields. Insects Mosquitoes, deerflies and horseflies are plentiful most of the summer, making insect repellent a must. Wildlife The Bridger Wilderness contains a rich diversity of wildlife species, including large mammals such as moose, elk, bighorn sheep, mule deer, bears (black & grizzly-see Bears and You for more information), yellowbellied marmots and beaver. Birds that are common include the Canada ('gray') jay, Clark's Nutcracker and raven. These birds frequently show up around camp when there is food around. The high meadows are home to water pipits, rosy finches and mountain blackbirds. The dipper may be seen in fast-moving mountain streams standing on streamside rocks, bowing and bobbing, until it decades to plunge into the icy water for insects. Historically, the Bridger Wilderness had no fish in most of its lakes. Stocking programs during the 1920's and 1930's were successful, and today grayling, mountain whitefish and six trout species can be found. Recreation Backpacking is the primary activity of people who visit the Bridger Wilderness, and many trails provide access to the area. There are also areas without trails for those who wish more solitude. Other activities include hiking, horseback riding and packing, mountain climbing, mountaineering, and wilderness camping. Please note: Motor vehicles, including snowmobiles, bicycles and hang gliders, are prohibited within the Bridger Wilderness. Water The water in the Bridger Wilderness looks clean and pure, but take care. Waters throughout the country contain a variety of organisms, some of which can make you very sick. The parasite Giardia, an organism present as a cyst in the feces of infected animals and humans, is most commonly spread through water. Other microbes, including Campylobacter, may also be around, and can upset your stomach and intestinal tract. Giardia: If you wish to treat your water for Giardia, boil it for one minute, or use a filter with a pore size less than one half micron. Campylobacter: Requires boiling for five minutes or filtering. Iodine water treatments may work if the directions are followed carefully. The effectiveness of iodine treatment is dependent on the type of iodine, freshness, exposure time, and temperature, purity and pH of the water being treated. Chlorine treatments are not recommended. Another option for short trips: Bring your water with you. Maps Topographic maps, trail maps, Wilderness maps, campground and recreation facility maps, and other useful guides are available locally in Pinedale at sporting goods stores. Additional information is also available at the Pinedale Ranger District and BLM Offices. Wilderness and You - Minimum Impact Camping Camping Select a campsite away from lakes, streams and other camps to preserve a feeling of privacy and solitude. Your campsite should be out of sight of trails and water bodies, or, where screening is not provided by vegetation or topography, a minimum of 200 feet from lakes or trails. Constant use of the same campsites leaves permanent scars. Soils become compacted and plant life is crushed and worn away. Campfire ashes accumulate and the area becomes visibly worn. If you use an existing campsite, leave it in better condition than you found it. Or, be a no-trace pioneer and select an unused campsite away from heavily used areas. Leave it natural! Select subdued colors for clothing and equipment. Browns and greens are best. Bright colors have a greater visual impact on the privacy and solitude of others. Campfires Campfires are permitted in the Bridger Wilderness with the exception of seven "special management areas". Lightweight gas stoves are more efficient and faster for cooking than fires, and they leave no impact. Campfires destroy organic matter in the topsoil and may inhibit plant growth for many years. Blackened rocks, charred wood, and accumulated ash also alter the natural appearance of the site. If a campfire is used, here are suggestions to minimize impact: A ring of rocks is unnecessary. Instead, dig a firepit about six inches deep, keep the sod intact and pile it nearby. On breaking camp, permit the fire to burn down to white ash and drown the coals thoroughly. If there is buildup of ash, remove it from the firepit and scatter it well away from camp, where people won't walk through it, and the rain and snow will wash it away. Replace the sod and pour water on it. Scatter any unused firewood in natural appearing locations. Keep your fire small to reduce impact and the danger of forest fire. Select a spot a safe distance from trees, brush, and down logs, Leave no firerings. Campfires are allowed below timberline using only down materials. Do not cut firewood from standing or live trees. Firewood Trees grow slowly at high altitude and fires consume wood which would otherwise decompose and replenish the soil with nutrients. Particularly in areas where trees are stunted and scarce, gathering firewood has a severe impact on vegetation. Burn dead and down wood and only that which is necessary. Standing dead and gnarled snags are components of the wilderness scenery and important habitat for cavity-nesting birds and many small mammals. Sanitation Bury human waste in a shallow hole at least 100 feet from any water supply, so that rain or snow runoff will not carry contaminants to lakes and streams. Studies have shown that decomposition of waste is best in holes dug 6-8 inches deep. Soap (even biodegradable brands) and food particles pollute lakes and streams. Please wash your dishes, clothes and yourself well away from shore. Carry out cans, bottles, plastics, aluminum foil and anything else that will not burn. Burying doesn't work. If frost action doesn't heave your buried garbage to the surface, animals will dig it up. Please, if you pack it in, pack it out! Pets Pets occasionally bother other visitors, wildlife and grazing livestock. Please keep your pets under control at all times and away from other people. Trail Etiquette Wilderness trails are constructed and maintained to minimize impact of human use. Short-cutting switchbacks and cutting across meadows damage plant life and cause soil erosion. Please use trails where provided. Hikers meeting horse parties on the trail should move a considerable distance off the trail and remain quiet and motionless until the horses pass, unless advised otherwise by the riders. Bright-colored gear, bulky packs, and sudden noise or movement may cause a horse to spook, resulting in general chaos, and injury to horses, riders and hikers. Curious pets can also cause a problem. It is advisable that pets be held until the horses pass. Please use the trails where provided. Registration & Permits Registration at the Ranger Station or Campgrounds is not necessary. Registration boxes are provided at all major trailheads, and visitors are asked to please register at these stations, and to add your comments and suggestions. Registers are used as a management tool by the Forest Service to provide essential information on visitor use and preference. This information helps Wilderness managers meet the needs of visitors and minimize impacts to the wild setting. Permits Permits are required for the following: Organized groups, All parties using pack and saddle stock overnight, Commercial uses (outfitters and guides). Group Use All organized groups (clubs, schools, church groups, scouts, etc.) are required to obtain a permit from the Pinedale Ranger District, PO Box 220, Pinedale, WY 82941, 307-367-4326. There is no charge for these permits as long as the groups are not commercial. You will need to provide the following information: Dates of trip Location of entrance, exit, and planned campsites Number of people in group (15 is maximum) Scout groups are also required to send a copy of the Scout Council Tour Permit, in advance of their planned Wilderness trip. Stock Use All overnight parties using horses within the Wilderness are required to obtain a permit from the Pinedale Ranger District Office. Permits are not required for day rides, unless commercial. The maximum permitted number of stock is 25 head per party. Commercial Use Commercial Outfitters operate under Special Use Permits for which a fee is paid.

Safety Wilderness has many potential dangers, which are part of the Wilderness experience. You must be prepared to take care of yourself. As a general precaution, it is wise to travel with another person and to tell a friend where you plan to be, and when you plan to return. Here are some other safety suggestions: Know basic first aid and carry a first aid kit. Even simple items, like aspirin and Band-Aid, can be very valuable to an injured person in the wilderness. Be aware of the weather. Even in mid-summer, it can change rapidly. It can snow any day of the year in the Bridger Wilderness area! In case of serious injury, treat the injury to the extent of your abilities and send for help. Leave one person with the victim. Notify the Sublette County Sheriff or Pinedale District Ranger. They will take steps to activate the local Search & Rescue organization. Allowed Uses Livestock Grazing Livestock grazing is permitted where such use was established before the wilderness was designated. Livestock grazing is administered under allotment management plans. Sheep graze the Bridger Wilderness from July to September. Herding practices are designed to minimize contact with recreationists. Brief encounters may occur in meadows from Cooks Lake south to the Sweetwater River. Cattle graze some of the western fringes of the Wilderness. Motorized use may be permitted in maintaining facilities or managing grazing allotments if no other reasonable alternative is available. Mining Mining operations on valid or patented claims are permitted indefinitely. Permitted mining operations in the Temple Creek/Schlestler Peak area, near Big Sandy Trailhead, involve occasional use of motor vehicles and equipment. Hunting and Fishing Hunting and fishing is allowed under state laws with a valid Wyoming hunting or fishing license. Licenses and regulations can be obtained from the Game and Fish Department, State of Wyoming, Cheyenne Wyoming 82002, or any appointed licensing agent throughout the state. Commercial Service Commercial services that facilitate enjoyment of the Wilderness are allowed. Commercial services are administered under special use permits. Outfitter camp permits may allow tent frames, hitch rails and corrals of natural materials at approved locations. These facilities may be left standing for brief periods between trips, but are normally dismantled at the end of the permitted season.
