Measurements were made of snow temperature at a depth of 10m beneath the surface during the oversnow traverses in 1968-1975 in the region of Mizuho Plateau. The mean annual surface temperature estimated from the 10m snow temperature decreases gradually from the coast to the inland, which mean temperature gradient with elevation is close to the dry adiabatic lapse rate in the area between 0m and 3000m and its value in the area between 3000m and 3800m is larger than -2℃/100m. A map of mean annual isotherms shows that the isotherms are similar to elevation contours, especially in the area lower than 3000m.
