Geography

The Klastline River originates in a valley on the Klastline Plateau between Tsazia Mountain and Mount Poelzer. From its source the Klastline River flows about 5 km (3.1 mi) north to the southern base of an unnamed circular, flat-topped mountain. It then flows generally west for about 30 km (19 mi) to the northeastern side of the Big Raven Plateau. From there, the Klastline River flows generally northwest for about 30 km (19 mi) along the northern end of the Big Raven Plateau through the Tahltan Highland to the western end of the Grand Canyon of the Stikine where it joins the Stikine River.

The Klastline River contains six named right tributaries. The first one is Morchuea Creek which flows southwest into the Klastline River. Konthil Creek is the second named right tributary which flows southwest into the Klastline River just northwest of Iskut. The third right tributary is Grass Creek which flows south into the Klastline River. Jokerslide Creek, the fourth named right tributary, flows southwest into the Klastline River. The fifth named right tributary, Cheeny Creek, flows southwest into the Klastine River east of Telegraph Creek. The sixth named right tributary is Detiaten Creek which flows west into the Klastline River just northeast of Telegraph Creek.

Only three left tributaries of the Klastline River are named. The first one is Tsazia Creek which flows north into the Klastline River. Kakiddi Creek, the second named left tributary, flows north into the Klastline River. The third named left tributary is Buckley Creek which flows northeast into the Klastline River east of Telegraph Creek.

The roughly 50 km-long (31 mi) Klastline River Trail begins at the community of Iskut on the Stewart–Cassiar Highway. It extends northwest and west along the Klastline River for much its length. The trail enters Mount Edziza Provincial Park at about 25 km (16 mi) where Kakiddi Creek drains into the Klastline River. After entering Mount Edziza Provincial Park, the Klastline River Trail traverses northwest along the Klastline River for about 10 km (6.2 mi) and then crosses the river at the northern end of Mount Edziza Provincial Park. From there, the Klastline River Trail traverses west for about 15 km (9.3 mi) to the northeastern end of Buckley Lake where it meets with the Buckley Lake Trail and Buckley Lake to Mowdade Lake Route junction.
