Iskut-Unuk River cones 3660 yBP
Start: 3660 yBP [1]
Event Type: Explosive
- Cone [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)."
From Wood and Kienle (1990): "Wood from a gravel lens in an upper group of light-colored flows yielded a C14 date of 3,660 yr BP."
