Abstract
South More Glacier is located in the headwaters of More Creek in the northern British Columbia Coast Mountains, between the Iskut River and Mess Creek. The glacier, which is 2 km wide and 10 km long, divides into southern (terminus 1010 m asl) and north-ern (terminus 1150 m asl) lobes about 5 km apart. The forefield of the southern lobe is characterized by an extensive outwash plain and residual till islands positioned inside the recently deglaciated forefield. The maximum extent of South More Glacier during the Little Ice Age is demarcated by a distinct trimline and a terminal moraine that crosses More Creek at 900 m asl. Reconnaissance surveys in July 2005 within 0.5 km downstream of the glacier snout led to the discovery of subfossil boles and stumps exposed in gullies eroded through the till islands.Dendroglaciological and radiocarbon analysis identifies the majority of the glacially-killed trees as having been entombed by an advance of South More Glacier into a standing forest around 1500 14C years BP. The discovery and dating of dendroglaciological samples to this interval documents one of the northernmost locations where the regionally-extensive First Millennial Advance has been described in the British Columbia Coast Mountains.
