Landforms/Geology Weakly developed schist geology and minor sedimentary strata. Very minor pockets of alluvium. Steep to moderately steep hill slopes; many inlets; minor beaches, fans and alluvium. Very indented and dissected coastline due to excessive marine submergence, resulting in numerous headlands, peninsulas and deeply recessed bays. Several islands of various sizes, (including Arapawa, Blumine, Pickersgill and Long Islands) separated from the mainland and each other by narrow passages. Regionally important geological feature: Long Island gravel cuspate foreland. Steep, small to moderate-sized stream catchments. Some low-gradient stream stretches and few freshwater wetlands (eg. Port Underwood). 2. Climate and Elevation Dry, temperate climate. Many areas frost-free. Limited cold air drainage and ponding. Moderately low rainfall: 1200-1400 mm. Summer drought common and drought possible any time of year. Summits moist. High maritime influence - surrounded by sea. Salt spray a major coastal influence in exposed situations - especially Port Underwood and Outer Queen Charlotte Sound. Exposure variable. Outer Queen Charlotte Sound and Port Underwood exposed to strong winds and occasional gales. Inner Queen Charlotte, Tory Channel and associated bays generally sheltered. Summits of higher peaks very exposed and wind-shorn. Low elevation: 0-640 m altitude range; mean altitude 170 m.a.s.l. App Two - 33
