Mount Whitney: North American Mountain Field Guide No. 003

Swipe notes

1. Cross-section. The card reads Whitney as a granite Sierra crest rather than a volcanic cone: the peak sits on the Sequoia National Park / Inyo National Forest boundary, and the shortest popular route from Whitney Portal is 10.7 miles one way. 1
2. Vegetation zones. The route bands use the NPS vegetation framework for Sequoia and Kings Canyon: montane forest below the high conifers, subalpine forest around 9,500-12,000 ft, then alpine habitat above treeline. The percentages are route-span estimates calculated from Whitney Portal to the summit. 2 3 4
3. Flora field cards. Red fir and lodgepole pine anchor the upper montane forest; foxtail pine and whitebark pine define the treeline story; sky pilot and oval-leafed buckwheat represent the exposed alpine zone. 5 3 4
4. Wildlife by elevation. The high country panel uses NPS-listed alpine and subalpine species such as pika, marmot, Clark's nutcracker, mountain bluebird, gray-crowned rosy-finch, mountain yellow-legged frog, and Sierra Nevada bighorn sheep; the forest row uses common park mammals and birds from the montane zone. 6 7 8
5. Season and difficulty. The main trail is usually snow-free from July to late September, with a quota season from May 1 to November 1. Day-use summit attempts are commonly described as 22 miles round trip, about 12-14 hours; the Mountaineer's Route adds Class 3 alpine terrain, route-finding, and snow gear when conditions require it. 9 10 11
