Description
Addresses salinity in the Roaring Fork River Basin, Snowmass-Glenwood Springs Area. Data suggests that dissolution of evaporitic rocks in regional structural collapse center contributes to salt loading in nearby streams. Maps and tables describe test locations and associated field measurements within study area. 21 pages, 2 figures, 1 color plate (1:1,000,000). Digital PDF download. IS-49D
From the Introduction:
The primary goal of this investigation was to develop a better understanding of the sources of salinity in the Roaring Fork River and its tributaries in the vicinity of the Carbondale collapse center. To accomplish this goal, field measurements of specific conductance, salinity, temperature, and pH were obtained on random point samples of springs and surface water at 112 test locations in October 1997. No water samples were collected for laboratory analysis, and discharge rates were not determined for the tested waters. Most of the measurement locations were situated along the Roaring Fork River and its principal tributaries, but several were also on the Colorado River and its tributaries in the vicinity of Glenwood Springs. Both hot and cold springs in the area were measured.
