Large-scale salt dissolution is an important process affecting the sediments of many of the saline lakes in the northern Great Plains region of western Canada. The most easily recognized features of this salt karst are water-filled chimneys
, vertical shafts, and collapse structures. Because these salt karst features can affect large vertical sections of the sediment fill in the lakes, their recognition is of fundamental importance in attempting to use the stratigraphic records of the basins

This paper reports on how geomorphic evidence has contributed to an understanding and definition of flooding hazards associated with closed-basin lakes in the Great Basin of the western United States and specifically with the largest of these lakes
Changing properties of snowpack in the Great SaltLake basin, western United States, from a 26-year SNOTEL record

Daily observations from automated snowpack telemetry (SNOTEL) stations from within the drainage basin of the Great SaltLake over the period from 1982 to 2007 are analyzed. The major finding is a shift toward an earlier date of peak snow water
equivalent (SWE) by around 15 days. This suggests increased chances of late-summer water shortages especially when combined with rapid recent population growth. Less freshwater is likely to be available to flow into the Great SaltLake, increasing its
Semicircular and crescent-shaped accumulations of salt crystals developed on salt crusts were measured on three Tunisian playas in September 1990. These features have been termed salt ramps. Their morphology and chemistry suggest
that they are formed in the late stages of shallow ephemeral lake dessication in playa basins. They appear to be short-lived features and their degradation is related to the flooding of playas with less saline water, and possibly rainfall and deflation.

Crafting a sense of place : media's use of the Bonneville Salt Flats
The Salt Flats, near the Utah-Nevada state line, are a scenic but chameleon-like landscape. Study identifies the factors that make the Salt Flats so appealing to filmmakers and to classify the types of places they create with it. The Salt Flats
are a visually stunning remnant of Lake Bonneville - stark whiteness surrounded by majestic mountains and blue sky. The four major themes of place portrayed are : land of human triumph, land of destruction and desolation, playground, and surreal spot
The Mormon experience : the plains as Sinai, the Great SaltLake as the Dead Sea, and the Great Basin as desert-cum-promised land
The experiences of the members of the Church of Jesus Christ of Latter-day Saints in migrating across the Great Plains to the valley of the Great SaltLake, in colonizing the Wasatch oasis, and in occupying major portions of the Great Basin gave

Tafoni and honeycomb weathering are described from indurated lacustrine silts and trachyte lavas respectively. Although salt weathering is responsible for the landform observed, it is acknowledged that they are convergent forms and can develop

The AA. present the species composition, size structure, and Sr 87/Sr 86 ratios of the precisely dated ichthyofauna from Homestead Cave, Utah, and discuss their implications for terminal Pleistocene and Holocene lake history in the Bonneville basin.

The AA. describe the stratigraphy of a 5.45-m-long sediment core from Mahoney Lake, a meromictic lake in southern British Columbia. Using changes in sediment alone, the AA. infer changes in lake levels from which they deduce changes in climate
. They infer many sharp oscillations in lake level, and they ascribe these to climate fluctuations throughout the Holocene.
