Sierra Nevada 在西班牙語的意思是白雪覆蓋的鋸子。Sierra Nevada 座落在北美洲大盆地(Great Basic)西南緣的山脈,遠看像一把鋸子,因此而得其名。由北到南全長約400英里(640公里),東西寬約70英里(110公里),最高的山峰,惠特尼峰(Mt. Whitney 14,505ft)。聳立在孤松鎮(LonePine)的西邊。著名的約翰穆爾步道(John Muir Trail)乃是沿著雪山(Sierra Nevada )山脊,北從優勝美地,南到惠特尼峰,全長共220英里。
大家都只知道約翰穆爾步道(John Muir Trail)這條縱走的路線,很少人知道High Sierra Trail 這條橫渡雪山(Sierra Nevada )。有人認為 High Sierra Trail 比John Muir Trail 更美,壯觀。
High Sierra Trail 全長 72英里,總爬升17490 ft ,總下降9718ft。因為西邊登山口在美洲杉國家公園,東邊登山口在孤松鎮,兩個登山口相距約7個多小時的車程,接駁上有技術上的問題,所以,很多人也就走來回,共130公里。
High Sierra Trail 西邊的入山證不用抽籤,比較好拿。 登山口在6700 英尺的Crescent Meadow ,沿著Middle Fork Kaweah River 往東行,越過不少溪流,還可以享受野溪溫泉,翻過分水嶺Great Western Divide, 經過Guitar Lake 從惠特尼峰的西邊登頂美國本土最高峰惠特尼峰(Mt. Whitney 14,505ft)。從這邊登頂比從東邊壯麗很多。
Day 1 - to Bearpaw Meadow (11.4 miles/18.2 km):The trail leaves from Crescent Meadow on the southeast edge of the Giant Forest. For the first half-mile, the trail travels through shady, well-watered terrain covered with dense forests of red and white fir, sugar pines, and occasional giant sequoias. The trail then emerges onto a warm, south-facing slope at Eagle View. From here, you can see back to Moro Rock to the west, down to the Middle Fork of the Kaweah River, and ahead to the glaciated peaks of the Great Western Divide. The nearly-level trail then passes through part of the area burned by the Buckeye Fire in 1980. Spring-fed streams cross the trail late into the season. Creek crossings may be hazardous early in the summer. Be sure to check conditions when you pick up your permit.
Beyond the junction with the Seven Mile Hill Trail, which connects the High Sierra and Alta Trails, the trail crosses the steep slopes and bluffs of the south side of Alta Meadow and Alta Peak. During 1930, a trail crew working with an air compressor and rock drills spent nearly the entire summer blasting a 1-mile (1.6 km) stretch of trail through this area.
Hikers taking a more leisurely trek to Mt. Whitney may wish to camp along one of the two forks of Nine Mile Creek (8.8 miles/14.1 km). After passing Nine Mile Creek, the trail descends to Buck Canyon, a spectacular canyon well-known for floods, avalanches and rockslides. After crossing Buck Creek, the trail climbs some 500' in slightly over a mile (152 meters in 1.6 km), arriving at the Bearpaw Meadow area 11.4 miles (18.2 km) from the trailhead. In addition to camp sites, this is the location of the Bearpaw Meadow Camp, a simple tent hotel run by the park concessionaire (reservations required).
