Vento Chairman, Subcommittee on National Parks, Forests, and Public Lands Committee on Natural Resources House of Representatives Dear Mr. Chairman: Concerned about alleged degradation of areas being considered for possible inclusion in the National Wilderness Preservation System (wilderness study areas), you requested that we provide you with information on the types and effects of activities in these study areas. As agreed with your office, we gathered information on areas managed by two agencies: the Department of the Interior’s Bureau of Land Management (BLN) and the Department of Agriculture’s Forest Service. Specifically, this report provides information on (1) legislative guidance and the agency policies governing wilderness study area management, (2) the various activities and uses occurring in the agencies’ study areas, (3) the ways these activities and uses affect the areas, and (4) agency actions to monitor and restrict these uses and to repair damage resulting from them. Appendixes I and II provide data on the number, acreage, and locations of wilderness study areas managed by BLM and the Forest Service, as well as data on the types of uses occurring in the areas. -

Idaho Comprehensive Wildlife Conservation Strategy
Challis Volcanics Section This section is dominated by mountain ranges, including the White Cloud Peaks, Pioneer Mountains, Smoky Mountains, Boulder Mountains, White Knob Mountains, and portions of the Salmon River Range. There are some glaciated areas. Major waterbodies include the Wood River, Big Lost River, and the Salmon River, and many perennial streams and alpine lakes exist. Elevation ranges from 1200–3600 m (4000– 11,800 ft). Climate is influenced by prevailing winds from the west and the general north–south orientation of the mountain ranges. Precipitation ranges from 25–120 cm (10 to 45 in) annually with an average of 56 cm (22 in). The majority of the precipitation occurs during the fall, winter, and spring. A rain shadow effect from the high mountain barriers to the west reduces precipitation in this section. Summers are dry with low humidity. Much of the precipitation that falls at lower elevations during summer months evaporates. The average annual air temperature is 3–10°C (34 to 50°F) but may be as low as –4°C (24°F) in the high mountains. The growing season ranges from 70 to 120 days. Approximately half of the land is forested and major land uses are timber harvest, livestock grazing, and recreation. Mining for gold and silver is also an important use. The Wood River Valley, including Ketchum, Hailey, and Bellevue, is the population center. Development in this scenic valley has been rapid and extensive during recent decades. Table 1.

Prairie Lakes Loop – Smoky Mountains
Prairie Lakes LooP – smoky mountains In October, 2015 I did a day hike to the last group of lakes that I hadn’t been to in the Smoky Mountains. The Smoky Mountains are north of Ketchum, ID approximately 20 miles. I had previously hiked two miles into Baker Lake with my family back in 2006 while camping at Wood River Campground. In 2010 I hiked the Norton Lakes loop on a daddy-daughter overnighter which also included Big Lost & Smoky Lakes. This area has been a fun area for me to take the kids. See 2010 Norton Lakes article: http://jasonbackcountry.com/wp-content/uploads/2016/07/NortonLakes.pdf A view west toward Miner Lake from Norton Peak The 10 mile roundtrip Prairie Lakes loop that I hiked includes a few Prairie Lakes/ponds and Miner Lake. I never fished any of these lakes but I suspect Miner Lake would be your best bet since it looked deeper. The Prairie Lakes seemed pretty shallow around the edges for the most part. Mill Lake didn’t seem like a good fishing destination to me and perhaps is too shallow for fish. Norton Lakes on a previous trip mentioned above had excellent fishing for average Cutthroat. I made a deviation from the loop at Miner Lake. Instead of heading back down the canyon on the trail, I hiked a trail up to the divide to get a view of Norton Lakes. I then hiked cross-country to Norton Peak from the pass and then dropped into the basin above Mill Lake. I caught the trail from Mill Lake down to the road and then walked up the road to get back to the trailhead where I parked my truck. -
The Pioneer Mountains in the Distance
This map shows the geographic relationship between the Pioneer Core Complex and the thrust belt, and the location of the Smoky Mountains, and the 2 lobes of the Idaho batholith. Here is a geologic map showing parts of Blaine and Custer Counties. The southeast corner of the map shows the geology of the Pioneer metamorphic core complex. The units shown in red and shades of pink are the Idaho Batholith, discussed in a later module. This is a closer-up and more detailed map of the Pioneer Core Complex, showing the faults, which unroof the core complex, most notably the Wildhorse Detachment System. View of Sun Valley Ski area, Christmas Ridge. Wood River Valley and the Pioneer Mountains in the distance. The sharp peak in the center background is Hyndman Peak, the tallest in the Pioneers. View from Pioneer Cabin on west side of Pioneer Mountains. Wildhorse detachment is on ridge on left side. Rocks of the lower plate, the core, are Paleozoic marbles and quartzites. Cliff in distance is Paleoproterozoic gneiss. View to the south of the Pioneer Mountains core complex. The prominent peak on the left is Hyndman Peak. The creek in the foreground is Wildhorse Creek. Aerial view of Pioneer Mountains core complex. The detachment fault is shown about halfway up the photo, along the transition between the grey, gentler sloped, vegetated cliffs change into rocky, steep cliffs. Note glaciated topography. View of the Lake Creek Detachment fault. This is an upper plate imbricate of the Pioneer Detachment. Note the quartz veining along the fault. The fault has been mined for silver and lead ore minerals in the Homestake Mine. -
Ore Deposits in the Sawtooth Quadrangle, Blaine and Custer Counties, Idaho
ORE DEPOSITS IN THE SAWTOOTH QUADRANGLE, BLAINE AND CUSTER COUNTIES, IDAHO. By JOSEPH B. UMPLEBY. INTRODUCTION. This report embodies the results of a rapid reconnaissance of the mining districts in the Sawtooth quadrangle, in Blaine and Ouster counties, Idaho. The exceptionally rough topography, the wide distribution of the ore deposits over about 868 square miles, and the short period (12 days) available for the work made the data col lected extremely fragmentary. As the information obtained is fuller than any that appears in the literature, however, it is desirable to place it on record. The principal sources of published information are scattered statements under the heading "Alturas County" in the reports of the Bureau of the Mint.1 Later reports-by the Director of the Mint do not contain information concerning the mines, and before the United States Geological Survey commenced to collect such information the principal mines of the region had ceased to be producers. GEOGRAPHY. The Sawtooth quadrangle is a high, mountainous area with sum mits at elevations of 9,500 to 10,000 feet above sea level and includes . the divides between three large drainage basins. Its southwestern part is drained by the headwaters of Boise River, its east-central and southeastern parts by Wood River and its tributaries, and its northern part by Salmon River. (See fig. 57 and PL III.) The Saw tooth Mountains run sinuously across the quadrangle a little north of its center. From the Salmon River side they rise abruptly from a broad valley floor, 7,000 feet in elevation, to heights of 9,000 or 10,000 feet, and here and there a peak rises 1,000 feet higher. -
