Iskut-Unuk River cones 5600 yBP

Start: 5600 yBP [1]

Event Type: Explosive

Event Characteristics:
  • Lava flow [1]

Description: From Hauksdottir and others (1994): "Three cinder cones are identified (Fig. 2 [in original text]). The youngest cone lies to the south and appears to have fed the two youngest flows. It appears to have repeatedly erupted lava which dammed both Tom MacKay and Forrest Kerr creeks (B.C. Hydro, 1985). This inference is based on 14c dating of plant remains in lake sediments associated with these ephemeral dams. These age determinations (Table 1 [in original text], B.C. Hydro, 1985; Read and others, 1989) suggest lava effusion occurred 3800, 5600 and 6500-6800 years ago; the Iskut River Canyon was eroded to its present configuration in the last 3600 to 3800 years (B.C. Hydro, 1985)."
