This project determines the sources and extent of salinity in the lower San Pitch River drainage and adjoining Gunnison Irrigation Company canal system in southern Sanpete Valley using data we acquired over two field seasons documenting water quality and quantity along different reaches within the San Pitch River and Twelvemile Creek as well as nearby canals and springs. We use geologic mapping and geophysical techniques (TEM) to isolate and identify regions in the subsurface that likely have an influence on river salinity. The data collected for this study provide information necessary to make targeted management decisions to reduce salinity and provide for a sustainable supply of acceptable/suitable quality irrigation water for the GIC and its water users. Overall, our maps emphasize areas of higher and lower salinity sources and show calculated salt load to the San Pitch River.

In cooperation with the U.S. Forest Service, the Utah Geological Survey mapped springs and groundwater dependent ecosystems on the Wasatch Plateau. Using remote sensing, GIS, and field checking, more than 400 points were compiled and plotted for use by the Forest Service.

Field Review Invitation

FIELD REVIEW INVITATION

Geologic Map of the Tooele 30′ x 60′ Quadrangle,
Tooele, Salt Lake, Davis Counties, Utah

led by Donald L. Clark (UGS Geologist) and Charles G. Oviatt (Emeritus, Kansas State Univ.; Lake Bonneville specialist)

May 9-10, 2017

Day 1 (May 9), meet at Department of Natural Resources building (1594 W. North Temple, SLC, south side of building); gather at 7:00 am, depart at 7:30 am sharp. Review of the eastern part of map area, and return to SLC.

Day 2 (May 10), meet at DNR at 7:00 am, depart at 7:30 am sharp. Review of the western part of map area, and return to SLC.

You are invited to attend a field review highlighting updated geologic mapping of the area west of Salt Lake City. The purpose of the mapping is to accurately describe the stratigraphy, geologic structure, geologic resources, and geologic hazards of the area. These maps are used for land management planning, geologic hazard evaluation, resource assessment and development, and education, as well as by the weekend hobbyist. The trip will be geared to cover a broad audience including geologists, government officials, and the general public.

Highlights

  • Quaternary geology, Lake Bonneville levels and chronology
  • Quaternary fault zones/Basin and Range structure
  • Tertiary sedimentary and volcanic rocks
  • Mesozoic, Paleozoic, Proterozoic stratigraphy
  • Tooele arch, Stansbury uplift, Uinta-Cottonwood arch (western extension)
  • Sevier fold-thrust belt architecture
  • Subsurface and geophysical data
  • Geologic hazards
  • Geologic resources

Information

  • There is no charge; please circulate this notice among your colleagues.
  • For planning purposes, we ask that you RSVP to the UGS (starrsoliz@utah.gov or 801-537-3300); trip questions to donclark@utah.gov or 801-537-3344.
  • Some stops will involve a few short, strenuous hikes.
  • A high-clearance vehicle is preferable; roads become difficult in wet weather; full fuel tank.
  • Please bring your own food, water, boots, hat, field clothes, and warm waterproof jacket.
  • If severe weather threatens, please call the UGS office on day before to see if rescheduled.
  • A signed liability and consent form is required for trip attendance.

This project was funded through the National Cooperative Geologic Mapping Program supported by the Utah Geological Survey and the U.S. Geological Survey.
