A rock (Mitchell rock) with a depth of 4 feet, lies 1 cables off Chang tu point, the north-west point of Chang tau island. The sea does not break on this rock, and there is nothing to indicate its position.
Position approximate, lat. 30° 15′ 45′′ N., long. 122° 15′ 40′′ E.
NOTE. To clear Mitchell rock, when entering Tac-shan channel from the north-eastward, Wasps islet should be kept open of the islet northward of Chang tau island, until Cliffs islet is just open of the western extreme of Chang tau island.
A rock (Baylis rock) with a depth of 4 feet, lies 11⁄2 cables off the south-west point of Chang tau island.
