Some highlights of the Rocky Mountains seen on a SIFT field trip

Each year the CSPG sponsors one student from every Geology program in Canada to attend the SIFT (Student-Industry Field Trip).  This is a sampling of what they see on the 4-day field trip through the Rockies.

tl_files/sites/ees/Images/info/sift01s.jpg Flying out to Calgary, the prairies are a checkerboard of fields and deep valleys.
The first view of the Rockies is often from the plane as it comes into Calgary. Here the mountain front by the Bow Valley shows off Mount Yamnuska and the McConnell Thrust. tl_files/sites/ees/Images/info/sift02s.jpg
tl_files/sites/ees/Images/info/sift03s.jpg The Three Sisters demonstrate the effect of a syncline (capped by the east - left - sister), an anticline (valley between east and central sister) and a thrust fault (valley between the central and west - right - sister).
The Bow Valley and Castle Mountain behind.  Castle Mountain is a klippe of Cambrian rocks thrust to the east (right in this view) over younger rocks. tl_files/sites/ees/Images/info/sift04s.jpg
tl_files/sites/ees/Images/info/sift05s.jpg The Crowsnest Mountain is formed by an open syncline.
Farther north, along the David Thompson Highway, spectacular steeply dipping dip-slope mountains are part of the Sawback Range. tl_files/sites/ees/Images/info/sift06s.jpg

The Takakkaw Falls flow from the Daly Glacier over a 300 m cliff of Cambrian limestone capped by harder dolomite layer.


tl_files/sites/ees/Images/info/sift09s.jpg The highest mountain in the Rockies is Mt. Robson, composed of Precambrian quartzite.

West of the Rockies lies the Southern Rocky Mountain Trench - formed by easily eroded Purcell Thrust. Beyond this (to the right) lies the Purcell, Selkirk and Monashee Mountains, part of the core zone of the Cordillera.

tl_files/sites/ees/Images/info/sift11s.jpg The highest metamorphic grades are in the Monashee Mountains. Here, at the headwaters of Adams River, folded marble and migmatite can be seen.
The oldest rocks in the Monashees are Precambrian Shield basement rocks, brought up to the surface by the Purcell Thrust - here the Malton Gneiss. tl_files/sites/ees/Images/info/sift12s.jpg
