%X ABSTRACT The Hokusai (H05) quadrangle is in Mercury¡¯s northern mid-latitudes (0¨C90¡ãE, 22.5¨C65¡ãN) and covers almost 5 million km2, or 6.5%, of the planet¡¯s surface. We have used data from the MESSENGER spacecraft to make the first geological map of H05. Linework was digitized at 1:400,000-scale for final presentation at 1:3,000,000-scale, mainly using a ¡«166£¿m/pixel monochrome basemap. Three major photogeologic units of regional extent were mapped: intercrater, intermediate, and smooth plains. Materials of craters£¿¡İ£¿20£¿km in diameter were classified according to their degradation state. Two classification schemes were employed in parallel, one with three classes and the other with five classes, for compatibility with existing MESSENGER-era quadrangle maps and the first global geologic map. This map will provide science context and targets for the ESA-JAXA BepiColombo mission to Mercury
