Rocks

Salish Mountains

Glaciated mountain- formed in:

  • Argillite, siltite, quartzite, and dolomite
  • Volcanic ash layers remain

Cabinet Mountains:

Quartzite

  • Foundation: Precambrian Belt Supergroup rocks
  • Carved and shaped by Pleistocene glaciation
  • Share many similarities to Purcell and Selkirk Mountains

Natural History

  • Peaks:
  • McGuire Mountain
  • Suton Mountain
  • Blackfall Mountain
  • Area:
  • 4,125 square miles
  • Extent:
  • 116 miles
  • Center:
  • 48 degrees 10' N; 114 degrees 48'W
  • Location:
  • Missoula
  • Kalispell
  • Elevation range:
  • 2500-7000 ft
  • Colors
  • Brown-The color brown is used to denote most contour lines on a map, which are relief features and elevations.
  • Green- to denote vegetation such as woods
  • Blue- is used to denote water features like lakes, swamps, rivers, and drainage.
  • Contour lines (Index, Intermediate, Supplementary)
  • imaginary
  • they are map artifacts used to represent paths or segments of Earth at an equal elevation.
  • Paths and segments are presented as elevations (vertical distance above or below sea level) and reliefs (the shape of terrain features on the Earth’s surface)
  • Purpose
  • Determine the height or depth of the terrain and the steepness of slopes.
  • Show location relative to major landmarks such as towns, lakes, ect.

The Salish Indians:

  • Salish Mountains are named for Native Americans that settled before Europeans
  • Originated in Pacific Northwest
  • Named Flatheads by Europeans.
  • Not a large tribe
  • Salish had a reputation for bravery, honesty, general high character, and for their friendly disposition towards the whites
  • Salish Tribe occupied the area around Flathead Lake
  • Salish Tribe still lives south of the Salish Mountains

The Cabinet Mountain Wilderness act-

  • Cabinet Mountains Wilderness
  • Created by an act of Congress in 1964
  • Protects the wildest portions of the Cabinet Mountains
  • Motorized or mechanized vehicles, including bicycles not allowed!
  • Camping and fishing are allowed with proper permit
  • No roads or buildings constructed
  • No logging or mining
  • Many mountain lakes and sky scraping peaks located in the Cabinets
  • Highest peak is Snowshoe Peak

Historical Perspective

Salish and Cabinet Mountains

  • Dominant structural elements in the area are the Lewis Thrust
  • Listric normal faults and additional thrusts carried on the plate of the Lewis Thrust
  • Origin of the Lewis Thrust was near end of a major mountain building event
  • Started around 170 million years ago with the collision of crustal plates
  • Compressive stresses of event resulted in detachment of lower Proterozoic rocks
  • probably overlying the underlying basement
  • Result is that Lower Proterozoic rocks (age of around 1,600 million years) now on top of rocks of Upper Cretaceous age (less than 100 million years old)
  • What we see today
  • Leading edge of the Lewis Thrust exposed in outcrop in the eastern part of Waterton-Glacier International Peace Park

Fun Facts:

Salish Mountains

  • Between Kalispell and Columbian Falls- Flathead Valley crosses (pg. 86 in RSG)
  • Low mountains west are composed of Belt Formations
  • To East: Whitefish and Swan ranges (pg. 86 in RSG)
  • Montana
  • Part of North American Cordillera
