Geology

Alteration processes:Capps (1913) describes strongly altered graywacke and slate underlying the white quartz conglomerate. Reed and others (1978) note hydrothermally altered zones similar to Thunder Creeks (TL032, TL058), at the headwaters of Treasure (TL030), Dutch (TL033) and Bear Creeks (TL017) and at an unnamed locality east of McDoel Peak (TL053). Mineralogy of the alteration is not described by either of these authors. However, based on its reported similarity to altered zones at Thunder Creek, it is most likely argillic alteration of Mesozoic sedimentary rocks.
