Involutions observed on the northern foot (38°30′N, 140°41′30″E, 540m. a. s. l.), of Mt. Funagata, Miyagi Prefecture, are well developed in the layers of the obanazawa pumice (ca 10, 000y. B. P., after Ui et al, 1973; Yonechi and Nishitani, 1975) and just above sandy loam. Solifluction deposits are observed on the land slide block of Kurumidaira landslide area (38°38′N, 140°33′E 670m. a. s. l.) near Obanazawa city, Yamagata Prefecture, are covered with the Obanazawa pumice. It seems that these phenomena had been formed during the last period of Pleistocene epoch.
