Franklin Glacier Complex  The Franklin Glacier Complex is a deeply eroded volcano in the Waddington Range of southwestern British Columbia, Canada. Located about northeast of Kingcome, this sketchily known complex resides at Franklin Glacier near Mount Waddington. It is over in elevation and because of its considerable overall altitude, a large proportion of the complex is covered by glacial ice. Magmatic activity of the Franklin Glacier Complex spanned roughly four million years from the Late Miocene to the Early Pleistocene, with the most recently identified volcanic eruption having taken place around 2.2 million years ago. The existence of thermal springs near the complex implies that magmatic heat is still present. It has therefore been of interest to geothermal exploration. The area lies in one of British Columbia's many territorial divisions called the Range 2 Coast Land District. Local relief exceeds with the long valley-filling Franklin Glacier originating from an icefield below the west face of Mount Waddington. It is part of the Waddington Range, a subrange of the Pacific Ranges which in turn are a subdivision of the Coast Mountains. The Franklin Glacier Complex was covered by the Cordilleran Ice Sheet until its retreat about 13,000 years ago. Franklin Glacier has since undergone glacial retreat and expansion throughout the Holocene. It appears to have retreated significantly during the early Holocene warm period, followed by advancements 6,300, 5,400, 4,600, 4,100, 3,100, 2,400, 1,500, 800 and 600 years ago. The timing of expansions corresponded with cool summer temperatures, generally moist conditions and increased precipitation. Minimal geologic studies have been conducted at the Franklin Glacier Complex and its geology is therefore poorly known. It measures wide and long, covering a northwesterly elliptical area of . Volcanic rocks of the Franklin Glacier Complex consist predominantly of dacite breccia, minor dacite flows and a few hornblende andesite remnants. An absence of pumice, glassy blocks or bombs in the breccia suggests that it may be of epiclastic origin, possibly formed during collapse and infilling of a caldera. The complex has therefore been described as a caldera or a cauldron subsidence. Heavy erosion of the volcanic rocks has exposed a series of biotite-quartz-porphyry, biotite quartz-feldspar-porphyry and quartz monzonite subvolcanic plutons and dike swarms.
