This dataset was used to summarize and analyze the mortality factors recorderd on dead trees in the Sierra Nevada Forest Dynamics Plot Network, which is managed by the Sequoia and Kings Canyon Field station of the U.S. Geological Survey's Western Ecological Research Center. Each row of the dataset represents an individual dead tree. These are dead trees that were recorded in the network from 1998 to 2010 for the subset of plots as described in the associated manuscript; These data support the following: Das, A.J., Stephenson, N.L., Davis, K.P. 2016. Why do trees die? Characterizing the drivers of background tree mortality. Ecology. 97(10): 2616-2627, https://doi.org/10.1002/ecy.1497

This dataset records mortality-- including involvement of bark beetles-- and burn severity information for trees in long term forest dynamics plots in Sequoia National Park and Yosemite National Park that experienced fire. These data support the following publication: Furniss, T.J., Das, A.J., van Mantgem, P.J., Stephenson, N.L. and Lutz, J.A., 2021. Crowding, climate, and the case for social distancing among trees. Ecological Applications, p.e2507, https://doi.org/10.1002/eap.2507

Yosemite National Park, California. Silhouette view of the gorge that separates Liberty Cap from the Nevada Fall platform. This gorge was, at one time, the channel of the Merced River and still carries off some of the flood waters in spring. The trail to the top of the Nevada Fall is laid through it. Circa 1913.
thumbnail
Yosemite National Park, California. Domes and knobs of the Tuolumne Basin, looking northwest from one of the domes. 1903.
thumbnail
Yosemite National Park, California. Cathedral Peak and granite domes, viewed from the trail near Ragged Peak. The highest dome is Fairview. 1903.
thumbnail
Yosemite National Park, California. Chief summit of Lembert Dome, viewed from a lower summit at the northeast. Tuolumne Meadows and Cathedral Peak in the distance. 1903.
thumbnail
Yosemite National Park, California. Vogelsang Peak and the hanging valley north of it. In the foreground is the Emeric-Fletcher Valley. 1903.
thumbnail
Yosemite National Park, California. Camp on the Tuolumne-Merced Divide 1 mile north of Cathedral Lake.
thumbnail
Yosemite National Park, California. Perched erratic on a low pedestal on the south slope of Illilouette Ridge. 1923.
thumbnail
Yosemite National Park, California. Yosemite Falls and surrounding cliffs, viewed from the valley floor. Only the head of Lower Yosemite Fall is visible through the trees. Dark zones of vegetation crossing the cliffs on the left reveal narrow terraces developed along zones of sheared rock. Sparseness of vegetation in the intermediate spaces is indicative of the absence of joints in the rock. Circa 1913.
thumbnail
Yosemite National Park, California. The High Sierra, viewed from El Capitan. Half Dome and the head of Yosemite Valley in the center. Freshly fallen snow whitens the distant peaks and gives them a wintry aspect representative in some measure of the conditions that prevailed during the ice age when large glaciers extended from the High Sierra down to the Yosemite region. Circa 1914. Plate 11-A, U.S. Geological Survey Professional paper 160.
thumbnail
Yosemite National Park, California. Cirque at the head of the valley of Yosemite Creek. The lake in the bowl has been transformed by alluviation into a wet meadow. The trail to Ten Lakes Basin crosses the saddle in the background. Circa 1914.
thumbnail
Yosemite National Park, California. Half Dome, viewed from Upper Quarter Dome, on the south side of Tenaya Creek Canyon. Strong shadow across the shoulder discloses the master joint (or shear plane) that may have determined the trend of the northeast face of the dome. Lower Quarter Dome in the foreground, showing exfoliation sheets breaking off along imperfectly developed joints. Circa 1913.

Yosemite National Park, California. Down Long Meadow. Circa 1914.

Yosemite National Park, California. East to the Divide where Monument 80 is located. Dorothy Lake in the foreground. 1906.
thumbnail
Yosemite National Park, California. Hetch Hetchy Valley, viewed from the trail to Lake Eleanor near the proposed dam site. View is northeast. 1906.
thumbnail
Yosemite National Park, California. Three-quarters profile view of Royal Arches, showing the inclination of rock sheets and in-curving of partings under the edge of the rock terrace, a feature characteristic of exfoliation. Half Dome in the background. Circa 1913.
thumbnail
Yosemite National Park, California. Summit of an unglaciated peak above timberline. The material is granite. It is broken into large blocks, which are disturbed as though by frost, but not transported. Their angles are usually sharp, and the crevices are not occupied by soil. 1903.
thumbnail
Yosemite National Park, California. Cascade Cliffs and Little Yosemite Valley. In few other places in the Yosemite region is the granite more continuously massive than in the Cascade Cliffs. Only one horizontal master joint divides the rock (in the lower left.) The scales on the cliffs are merely surficial features due to exfoliation. The dark streaks indicate the paths followed by the ribbon cascades which descend from the upland in the spring, when the snow is melting, and from which the cliffs take their name. In the background is Sugar Loaf (Bunnell Point). Circa 1914. Plate 45-A, U.S. Geological Survey Professional paper 160. Note: The Francois E. Matthes' papers and field notebooks are housed in the Brancroft...
