Frost wedging.

Reason: In alpine Whistler, repeated freeze–thaw of water in cracks pries the rock apart, producing angular fragments and blocky breakdown. Abrasion would show smooth, scratched surfaces (glacial or wind polish); pressure release gives sheetlike exfoliation; salt weathering occurs in arid/coastal saline settings.
