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

Sequoia National Park, California. Southeast from the base of Moro Rock. Castle Rocks on the right. Great Western Divide on the left. Turtle Rock in the foreground. Photo by L. Eddy, 1925.

Sequoia National Park, California. Ancient Indian pit, about 5 feet in diameter, resembling a stream-worn pothole in the surface of an exfoliating granite boss near Ranger Headquarters in Giant Forest. 1925. See also photo mfe00681.

Sequoia National Park, California. Snow chutes in massive exfoliating granite, viewed from Bearpaw Camp at the head of the canyon of Middle Fork Kaweah River (Valhalla). 1936.
thumbnail
Sequoia National Park, California. Glacier polish, striae, and grooves above the head of Kern Canyon. The rock is aplite, which weathers more slowly than the coarser granite and, therefore, holds its glacial markings longer. Since being glaciated, the aplite has been somewhat disrupted into angular blocks by repeated frost action. Circa 1935. Figure 23, U.S. Geological Survey Professional paper 504-A.

Sequoia and Kings Canyon National Park. Step in valley of Evolution Lakes, Sierra Nevada, seen from sill of hanging valley. At left Mt. Goddard. (Compare with no. 2387). Fresno County, California. 1904.
thumbnail
Sequoia National Park, California. Kern River, cutting in bedrock, near Kern Canyon Ranger Station at the south border of the park. Circa 1935. Figure 37, U.S. Geological Survey Professional paper 504-A.

Sequoia National Park, California. Current polish and potholes in the bed of the Kaweah River below Three Rivers. Photo by J.C. Patten, 1935.
thumbnail
Sequoia National Park, California. Up "River Valley," the glaciated upper canyon of Middle Fork Kaweah River. Cliffs in the foreground show exfoliation. 1936. Figure 33, U.S. Geological Survey Professional paper 504-A.
thumbnail
Sequoia National Park, California. Across the glaciated floor of Whitney Canyon, showing combined effects of quarrying and grinding.
thumbnail
Sequoia National Park, California. Side of Diamond Mesa, viewed from the west. Though reduced in area by glacial erosion, the mesa itself has remained unglaciated, like the Boreal Plateau, because snow has never accumulated to sufficient depth on its wind-swept surface. The summit of Junction Peak stands high above the mesa and bears a vestige of a still higher erosion surface, presumably the Cirque Peak surface. 1935.
thumbnail
Sequoia National Park, California. South slopes of Alta Peak. The mountain side, composed of massive granite, is exfoliating on a large scale. In the foreground, old exfoliation shells, long detached, are breaking up into angular blocks as a result of frost action in incipient joints. Circa 1935.
thumbnail
Sequoia National Park, California. One of the many lakelets occupying glacially quarried rock basins in the upper Kern Basin, above the junction of Milestone Creek. The granite at the sides, being only sparsely fractured, was not readily quarried away and consequently shows the effects of abrasion. Circa 1935. Figure 13, U.S. Geological Survey Professional paper 504-A.
thumbnail
Sequoia National Park, California. Black Kaweah and Red Kaweah, viewed from one of the Little Five Lakes. Circa 1935.
thumbnail
Sequoia and Kings Canyon National Park. Lake at southwest base of Mt. Goddard, Sierra Nevada. At left the slope of Mt. Goddard. Across the lake a medial moraine, beyond which is another lake. Beyond the low saddles at right and in middle of view are glacial troughs descending toward the east and southeast. These have been truncated by the development of the trough containing the lakes. For lakes compare 2401 and 2402; for the head troughs compare 2411 and 2414. Fresno County, California. 1904. (Panorama with photo no. 2399).

Sequoia National Park, California. Cirques on Mount Needham.
thumbnail
Sequoia National Park, California. Mount Whitney, viewed from the west. The precipitous cliffs of the mountain, the scoured bedrock floor of the canyon, and the small lake in the foreground are typical features of the glaciated upper Kern Basin. The cliffs are furrowed by avalanche chutes. Photo by W.L. Huber. Figure 46, U.S. Geological Survey Professional paper 504-A.
thumbnail
Sequoia National Park, California. Hamilton Lakes and the large cirque-like hollow in which they are situated. This hollow is not a cirque in the strict sense. The basin of these lakes marks the confluence of three glaciers that issued from cirques lying 1,700 to 2,000 feet higher. The three converging glaciers, descending from the 1,700-foot cliffs, excavated the basin of Hamilton Lakes in what is really a canyon step. The streamlet cascading down the cliffs comes from the middle one of the three cirques which contains Upper Hamilton Lake. Circa 1935.
thumbnail
Sequoia National Park, California. Down the canyon across one of the Hamilton Lakes, viewed from near the source of Hamilton Creek. Massive granite forms the impressive cliffs on the right and the rock barrier across which the lake has its outlet. In the center, on the distant mountain, is a well-formed avalanche chute. Photo by W.L. Huber, circa 1935. Figure 35, U.S. Geological Survey Professional paper 504-A.
thumbnail
Sequoia National Park, California. The largest and most perfectly formed avalanche chute in the park, viewed from the High Sierra Trail east of the camp in Bearpaw Meadow. Like its smaller companion, this chute is carved in massive exfoliating granite and terminates at the brink of the glacial U-shaped canyon below. The downward narrowing of the chute is explained by the protection given to the lower part of the chute by a snow cone on the surface of the glacier which lays in the canyon. Circa 1935. Frontispiece, U.S. Geological Survey Professional paper 504-A.
