[3] Tenchen Creek is in Mount Edziza Provincial Park which lies within the traditional territory of the Tahltan people.
[1][6] From its source, Tenchen Creek flows about 4 km (2.5 mi) east-northeast through conifer forest into the broad hummocky lowland of Kakiddi Valley.
[2][4] At the head of Tenchen Creek is an active cirque that has breached the eastern side of Mount Edziza's ice-filled summit crater.
Exposed in the cirque headwall are hydrothermally altered rocks of the central volcanic conduit, as well as lava lakes that once filled the crater.
[7] In the north fork of Tenchen Creek valley is a 210 m-high (690 ft) barrier of volcanic rocks called Cinder Cliff.
