煤礦的大露頭 / Sekitan-no Dai Rotou

煤礦的大露頭（位於夕張市）是北海道指定的天然紀念物。1888年，在地面上發現了高達7公尺以上的裸露的煤炭地層。此發現造就了夕張市成為煤礦產地主要都市的契機。現在這個地點緊臨於煤礦博物館的停車場，可以自由參觀。煤礦博物館於2018年4月整修後重新開幕。

Sekitan-no Dai Rotou (Yubari City) is designated as a prefectural treasure of Hokkaido. Sekitan means coal and rotou means outcrop; and Sekitan-no Dai Rotou stands for a large-scale outcrop of coal. In 1888, an exposed coal layer, in excess of seven meters in height, was discovered. This saw the bitrh of Yubari becoming one of the main coal mining hubs of Japan. Sekitan-no Dai Rotou is now located next the parking of the site of the Coal Museum. Although the museum is paid, this site is free to see. The Coal Museum was renovated in April, 2018.
