Death Valley National Park, California. Salt saucers, climax of the salt wedges and polygonally cracked salt crusts. The secondary cracks have so widened, the crusts have been thrust outward. These were old enough when photographed to have collected some silt (dark surface in lower left), and the bottom of each saucer is pierced by one or more drain holes. These saucers, one mile west of Badwater, were destroyed by solution when flooded in 1969. Figure 57, U.S. Geological Survey Professional paper 494-B. Drawing of photo.

Death Valley National Park, California. Parts of the flood plain that are perennially damp, or even wet, develop a hummocky blister-like growth of silty salt. A recent flood that spread onto this ground deposited new salt (white) in the depressions, but there was not enough water to destroy the blister-like hummocks. Circa 1960.

A high spatial resolution storm surge model was developed for the YK Delta area to assess biological impacts of storm surges under current and future climates. Storm surges are expected to be more frequent and more severe in the YK Delta area due to climate change and sea level rise. The biological impacts in the YK Delta due to the changed storm surges could be extreme.The model was assessed with respect to measured water level data at the coast and, where available, spatial extent of inundation, for 6 storms from the period 1992 to 2011. In total, inundation projections from 9 historical storms (5 from the assessment + 4 others) were developed. For each storm, an spatial inundation index (time-integral of water...

Death Valley National Park, California. Amargosa River at Coyote Hole near the south end of the salt pan. View is northwest and downstream. At the time of the 1969 floods, this channel, 120 feet wide and 3 feet deep, was filled almost to overflowing. Channel slope is 12 feet per mile, and the peak discharge must have been on the order of 750 cubic feet per second or 1,500 acre feet per day. Downstream where the river turns right, the channel is in an arroyo about 10 feet deep. This arroyo may be due to arching of the salt pan by uplift at Mormon Point. Circa 1960.

Deposits of glacial Lake Nashua, looking southeast from French Hill. Terrace of Boylston stage at 480 feet A.T. northwest of Boylston Center, Mass., seen in the distance. Terrace of Clinton stage in the foreground. Valley at present flooded up to 367 feet A.T. as Wachusett Reservoir. Marlboro quadrangle. Massachusetts. August, 1906.( Sun, slightly hazy, Ex. 1, D 16). Handwritten note on album caption: Worcester co, massachusetts.

Death Valley National Park, California. Salt Creek opposite Furnace Creek fan is not dry enough, commonly, to be forded by coyotes and four wheel drive vehicles. It can discharge formidable floods sufficient to erode the channel. Note the coyote tracks preserved beneath the water lower right. Circa 1960.

Death Valley National Park, California. One of the major floods off the east side of the Panamint Range is recorded by a considerable collection of juniper and pine logs at the foot of the Trail Canyon fan. Some of the logs are 6 feet long and 12 feet in diameter; they must have been transported to the toe of the fan from the very head of the canyon. Such an unusual flood may have been caused by an accumulation of snow followed by sudden thaw and warm rain. Circa 1960.
