Vertical Distribution of Underground Temperatures at a Boring Well in the Mamigasaki Alluvial Fan, Yamagata Basin

In 1958, the test boring was carried out at Momiji Park, Yamagata City to obtain information on geological strata vertically from the ground surface. At this bore-hole, the vertical distribution of the temperatures with the result as is shown by the figure in the text. Here, the Quaternary system consists of several layers classified by heat conductivity. Among them E, G and H layers in the same figure are deduced to be important aquifers.
