Different types of rocks respond to weathering and erosion in different ways. The coincidence
of inter-layered formations of shale and sandstone/conglomerate, their northwesterly aligned
folded structure, the eroding power of southeasterly moving glacial ice and the modern southeasterly
or northwesterly directed wind-driven waves and storm patterns have resulted in the prominent
northwesterly-southeasterly alignment of the Gulf Islands. Throughout these beautiful islands
the prominent headlands and high ridges are formed from comparatively erosion-resistant sandstone/conglomerate
whereas the narrow bays and valleys are sculpted from softer and more easily eroded shale.
