Garibaldi Park Whistler A to Z: ErraticErratic or Glacier Erratic is a piece of rock that has been carried by glacial ice, often hundreds of kilometres.  Characteristic of their massive size and improbable looking placement.  Erratics are frequently seen around Whistler and Garibaldi Provincial Park.  Either as bizarre curiosities or a place to relax in the sun.  On a sunny day, a large sun-facing erratic will often be warm and sometimes even hot, providing a comfortable and surreal place to rest.

During the last ice age, glaciers covered British Columbia, and where Whistler is today, the glaciers were two kilometres thick.  Glaciers from the last ice age can often be measured by the grinding marks made on the mountains they covered.  In the mountains around Whistler you can see just a few that poked through the glaciers, leaving their peaks jagged.  Other, shorter mountains around Whistler can be easily recognized as completely covered in ice.  Shown by their rounded, glacier ground peaks.  For an erratic to be considered a true erratic it must lay in an area with dissimilar rock types.  For example, rock and mountains around the erratic should be of different colour, texture and composition.  An erratic should look very out of place and distinct from its surroundings.

Erratics are frequently the result of glaciers carrying or grinding the erratic as it slowly moves down a glacier valley.  Rock slides from mountains can deposit house sized boulders onto a glacier which then slides down a valley for centuries, eventually releasing it.  These erratics are easy to trace back to their parent rock by matching them to identical rocks up the likely ice flow route.  Ice rafting is another way erratics have been moved great distances.  Ice rafting results from an ice dam breaking apart and tremendous volumes of water and ice flooding through.  These erratics are often detected by the high water marks left by the floods that moved them.  Another cause of erratics is via icebergs floating in the ocean and eventually releasing the rock encased in the melting ice.

Two Fantastic Books About BC Hiking!

Scrambles in SW BCA Passion for MountainsHere are two excellent books on hiking and geology of British Columbia.  Matt Gunn's Scrambles in Southwest British Columbia includes the various routes to the summit of Wedge Mountain as well as summit routes to the neighbouring peaks, Weart, Cook, Parkhurst and Rethel.  Mount Weart is the second highest mountain in Garibaldi Park and is located just north of Wedge Mountain, separated by the Wedge-Weart Col.  Published in 2005, Scrambles in Southwest British Columbia is still the best guide in print or online.  A Passion for Mountains by Kathryn Bridge is a fascinating look at Don and Phyllis Munday's prolific exploration of the mountains in BC.  Based out of Vancouver, they were dominant figures of the climbing community in the early 1900's.  In 1923 they visited their friend Neal Carter in Alta Lake(Whistler) and explored the mountains around the valley.. many for the first time!
