| KJts-1. View to north of the Twin Sisters Range [MBsw] from west of Howard Creek; South Twin on left. The Range is a large slab of dunite (KJts) from the Earth’s mantle within the Bell Pass mélange (KJb). Geophysical work shows the slab to be about 1 km thick. Rock in foreground is correlated with the Darrington Phyllite (Ked) and is separated from the mélange by a high-angle fault in intervening Howard Creek canyon. |
