Artifact Creek's watershed covers 42.5 km2 (16.4 sq mi) and is entirely in Mount Edziza Provincial Park. The creek's mean annual discharge is estimated at 1.62 m3/s (57 cu ft/s).[5]
The name of Artifact Creek and nearby Artifact Ridge and Obsidian Ridge comes from the abundant piles of stone chips left from the knapping of obsidian tools and points by early Tahltan hunters.[1][9]
Geography
Artifact Creek originates near Kitsu Peak, about 30 km (19 mi) south of Mount Edziza. It flows east and southeast between Obsidian Ridge to the south and Artifact Ridge to the north. It collects various small unnamed tributary streams before emptying into Stewbomb Creek about 3 km (1.9 mi) upstream from Stewbomb's confluence with the Little Iskut River.[2][10]
Geology
The north side of Artifact Creek is bounded by a 180 m-thick (590 ft) sequence of lava flows belonging to the Armadillo Formation of the Mount Edziza volcanic complex. A single 9 m-thick (30 ft) ash flow deposit also belonging to the Armadillo Formation is exposed on the south side of Artifact Creek. Along the north side of Artifact Creek are two poorly exposed, low, northeasterly trending ridges of trachybasalt that may be intrusions linked to the Little Iskut conduit system.[11]
