Fig−29. The discovery of submerged forests in situ to prove that the continental shelves were once to be the land. The location is off the coast of Nyuzen Town along the shore line of Kurobe River Alluvial Fan, Toyama Prefecture facing the Sea of Japan. The tree trunks distribution depth ranging about 20m〜40m. The first discovery was made in 4th May, 1980. (Fujii, S, Nasu, N. et al., 1986)
