Pitt Island is an island located on the north coast of British Columbia, Canada. [1] The island is of cultural and ecological importance. [2]

Contents

Pitt island is located between Banks Island, across Grenville Channel (part of the Inside Passage) from the mainland, and is separated from Banks Island by Principe Channel. [3] The island is mountainous and heavily dissected by valleys, fjords, and inlets and has an area of 1,368 square kilometres (528 sq mi), is 90 kilometres (56 mi) long, and ranges from 8 to 23 kilometres (5.0 to 14.3 mi) wide. Its highest point is at 962 metres (3,156 ft).

Pitt Island is the only island in British Columbia known to host a resident population of moose. [4]

History

The Gitxaala occupied the island in the past, with a fishing and hunting village for each family group, [5] and have identified this island as part the laxyuup(traditional territories and waters) [6] of the Gitxaala. [7]

Geology

Pitt Island lies within the Coast Range Arc, part of the broader Coast Mountains geological province formed by subduction and terrane accretion along the edge of North American Plate. The island is part of an ancient collage that makes up the British Columbia Coast, where multiple island arcs and seafloor were accreted onto the Continental margin over hundreds of millions of years. The Coast Range Intrusive Complex, which includes Pitt Island, formed primarily in the mid to late Mesozoic as subduction processes drove extensive magmatism and crustal growth [8] .

The dominant bedrock consists of intrusive rocks, mainly diorites and quartz diorites of acidic composition, that make up much of the island’s interior. These rocks represent magma that crystallized deep underground during the Cretaceous and were later exposed at the surface by tectonic uplift and erosion [8] . Like much of the coast, the island's superficial deposits, soils, colluvium, and glacial drift, were influenced by Pleistocene glaciation, which carved steep relief across the landscape [9] .
