The evapotranspiration rates of irrigated mountain meadow grasses were measured using non-weighing lysimeters during the 1979 and 1980 growing seasons. The lysimeters were located in a line across the Little Laramie River Valley near Laramie, Wyoming.

A project in west-central Colorado demonstrated that a watershed dissected by a dense gully network can be stabilized and rehabilitated. Check dam systems, aided by improved vegetative cover through reduced cattle grazing and plantings, stabilized not only the structurally treated gullies, but also gullies within the network that were not structurally treated. Comparison with untreated gullies located outside of the project area, showed that the outside gullies widened three times as much as the structurally untreated inside gullies.

Two pumiceous tephra layers, widespread in meadow topsoils of the southern Sierra Nevada, are correlated on the basis of radiocarbon dates and trace-element analyses with two eruptive centers at the northern and southern ends of the Mono Craters--Inyo craters volcanic chain in eastern California. Pumice and obsidian that were erupted in the northern part of the chain are uniform in trace-element content, whereas those erupted from the southern part are nonuniform and distinctly different, particularly in Sr content.

Valley-fill deposits, exposed by Twentieth-Century dissection of a number of meadows on the west slope of the southern Sierra Nevada, contain a stratigraphic record strongly affected by secular variations in watershed hydrology during the Holocence. Meadows are situated in low gradient reaches, adequately supported by seepage water, where fine textured materials accumulate under present hydrologic conditions. Meadows do not necessarily owe their origin to glacial modification of drainage.

Birch Creek, a small stream with headwaters in the White Mountains of eastern California, was studied during the spring of 1961 and the summer of 1962 to determine the environmental controls on travertine deposition. Although in an arid region and ephemeral for most of its length, Birch Creek has perennial flow which starts with ground-water discharge in a wet meadow and continues for about14 miles before disappearing into valley alluvium.

Ecological changes in the vegetation of mountain meadow-lands in the West have recently attracted much attention as a phase of the erosion problem. Ordinarily, too little information regarding the specific history of these changes is available to permit accurate analysis. The history of the case treated in the following paper is, however, unusually well known. Mountain Meadows in southwestern Utah is a spot of much local historical interest.
