Beautiful granite slabs make for an easier terrain, great picnic areas and flat, smooth campsites. Expect to hike through pine forests and fields of Manzanita brush. Manzanita, which literally means "little apple" in Spanish, is charac- terized by orange or red bark and twisting branches. Sometimes Manzanita grow to the height of small trees. The mountain ranges of California are known for their excellent light quality, referred to as alpenglow. When the sun is just below the horizon, a red glow can sometimes be seen on the opposite horizon. Look for alpenglow after sunset or before sunrise, when there is no direct sunlight. Instead, light reflects off airborne snow, water, or ice particles low in the atmosphere. At any time of day, the views above tree line are stunning. During wildflower season, late spring through early summer, expect lots of lupins, paintbrush, columbine, and California poppies. Watch for marmots and pikas--they are everywhere. 4 Route Description Overview Start at Agnew Meadows and make your northwestern loop journey up to Carson Peak or Emerald Lake. Details Agnew Meadows is the start of this loop. Go NW to Shadow Lake. Head up north to Altha Lake. Most groups will continue to Badger Lake and summit at Carson Peak. Go NE and at Middle Fork, NW to Badger Lakes. Summit at Carson Peak for stronger groups. Other groups can summit at Thousand Island Lake. Stay two nights at Altha Lake. From Altha Lake go west on the John Muir Trail, then NW past Ruby and Emerald Lakes. Beyond Emerald Lake is the summit.

Refer to trail map for corresponding locations. 11 Area History These trails travel through national forest and a wilderness area, both public lands, owned by the federal U.S. government and pro- tected from private commerical development, but for different pur- poses. The initial and continued mission of the National Forest Ser- vice, established in 1905 (within the Department of Agriculture), is: "...the greatest good of the greatest number of people in the long run.” Focused on conservation, timber and mineral deposits are managed in a manner similar to agriculture or farmed crops. Wilderness Areas were established with preservation in mind. The Congressional Wilderness Act of 1964 was approved to “secure for the American people of present and future generations the benefits of an enduring resource of wilderness.” As such, Wilderness desig- nation protects the area from roads, logging, oil and gas drilling, and any commercial enterprises. In part, to retain the quiet, motorized and mechanical vehicles and motorized equipment are not allowed. Local Environment The Sierra Nevada Mountains are an uplifted, tilted block of granite 400 miles long by 100 miles wide; the result of fault-line tectonic plate activity. Subsequent erosion, due to streams and glaciers, carved out U-shaped valleys, lakes, rugged peaks and cliffs. Sedi- ment fills lakes creating meadows. There are several threats to the natural condition of the Sierras: air pollution, light pollution, and global warming, evident in the thinning snowpacks. Stray light, particularly from San Joaquin Valley, bright- ens the night sky. Darkness allows vistors views of the stars, while nocturnal animals depend on darkness to hunt, conceal their loca- tion, navigate, and reproduce. Artificial light can disrupt plant cycles. 12 Daily Outline Recommendations • Expedition Preparation and Planning • Meet at BCM Office • Issue Individual Gear Day Agnew • Pre-trip teen surveys Meado 1 Camp • Duffle Shuffle • Issue BCM Group Gear • Camp at Agnew Meadows Campground Camp at Shadow Lake: 3.34 miles Day 2 Head west following the John Muir Trail.
