Map showing length of freeze-free season in the Salina quadrangle, Utah
1972, IMAP 591-E
In general, long freeze-free periods occur at low elevations, and short freeze-free periods occur at high elevations. But some valley floors have shorter freeze-free seasons than the glancing foothills because air cooled at high elevations flows downward and is trapped in the valleys. This temperature pattern occurs in the western...

Recent activity of glaciers of Mount Rainier, Washington
Robert S. Sigafoos, E. L. Hendricks
1972, Professional Paper 387-B
Knowing the ages of trees growing on recent moraines at Mount Rainier, Wash., permits the moraines to be dated. Moraines which are ridges of boulders, gravel, sand, and dust deposited at the margins of a glacier, mark former limits of a receding glacier. Knowing past glacial activity aids our understanding...
Falling-stream turbidimeter as a means of measuring sediment concentrations in streams
Harold P. Guy, Richard C. Olson
1972, Report
An optical (photocell) sensing device was used to measure the relative transparency characteristics of sediment suspensions with a view toward improving our ability to measure the temporal variations of suspended-sediment concentration moving in streams. The instrument used was a commercial "falling stream" turbidimeter that measured the relative transparency of a...
