The North March was a route used for communication between Ta-Koro and Ko-Koro. The Ta-Koro Guard maintained an outpost at the Ko-Wahi end of the March, but it was destroyed and its Matoran killed by Makuta Teridax. Takua traveled here to find out what had become of the Ta-Matoran who occupied the area. He also continued his quest here, finding Kopeke frozen in a glacier, and using his Heat Stone to free him.
