Salmon Glacier:  Repeat Photography

Salmon Glacier as seen from Granduc Road

The loss of volume at the Salmon Glacier terminus since 2011 is evident and stunning.  During recent decades loss of volume at the terminus is common for many of the largest Coast Mountains glaciers.  See an assessment of recent thinning here. The 2011 repeat image was taken within about 100 meters of the original location, but growth of vegetation at the roadside makes a repeat image from this location difficult.  With continued vegetation growth this task will be yet more difficult or impossible in the near future.  The 1978 image is used here with permission from the Royal BC Museum.

Both images were taken from along Granduc Road, but from slightly different locations.  However, reference to common landmarks reveals the dramatic thinning that has occurred in recent decades.  The 1978 image is used here with permission from the Royal BC Museum.  Thanks to Theo Mlynowski for taking the 2011 image (May 2011) and submission to GlacierChange.org!

Salmon Glacier as seen from near the summit of Granduc Road

While extent change of Salmon Glacier is not visible from this vantage point it is possible to see surface height change resulting in a loss of volume.  See an assessment of recent thinning here.   The Granduc Road is visible in the lower left.  The small parking lot is located at the high point (summit) of the road before descending to the Granduc Mine site and Berendon Glacier.

Small glacier above Salmon Glacier as seen from near the summit of Granduc Road

This small mountain glacier is just above the primary terminus of Salmon Glacier.  The bedrock knob in the foreground is the location of the photos of ‘Salmon Glacier as seen from near the summit of Granduc Road’ (above).  The variable lighting in the two images makes viewing of change from 2003 to 2011 difficult.  However, it appears that this small glacier has undergone little to no extent change over this period.
