Sep 30, 2020 (Therese Pettigrew) - North of Trout Bay the predominant metavolcanics are felsic and comprise: flows, tuff breccia, and lapilli tuff north of Dean Creek; tuff, lapilli tuff, and some reworked phases thereof south of Dean Creek and northwest of Trout Bay; and foliated feldspar and quartz-feldspar porphyry with subordinant lapilli tuff and rarely, tuff breccia in the Middle Bay-Sadler Bay area. Intermediate pyroclastics are common south and west of the west end of Middle Bay. Units of foliated to massive and rarely pillowed mafic flows averaging about 250 feet thick and units of interbedded chert-magnetite iron formation, ferruginous chert, and siltstone up to 200 feet thick and of variable length are intercalated with the felsic pyroclastics. A unit of interbedded ferruginous marble, chert, and minor argillite up to 1,000 feet thick lies north of Trout Bay (Riley, 1970).
