==Geography== The Klastline River originates in a valley on the [[Klastline Plateau]] between Tsazia Mountain and Mount Poelzer.<ref name="CGNBD">{{cite cgndb|id=JAJTF|title=Klastline River|access-date=2023-09-27}}</ref> From its source the Klastline River flows about {{convert|5|km|abbr=on}} north to the southern base of an unnamed circular, flat-topped mountain.<ref name="KF"/><ref name="CGNBD"/> It then flows generally west for about {{convert|30|km|abbr=on}} to the northeastern side of the [[Big Raven Plateau]].<ref name="KF"/><ref name="HR"/> From there, the Klastline River flows generally northwest for about {{convert|30|km|abbr=on}} 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.<ref name="KF"/><ref name="HR"/><ref>{{cite cgndb|id=JAUUU|title=Grand Canyon of the Stikine|access-date=2023-09-26}}</ref>

The Klastline River contains six named [[right tributaries]]. The first one is Morchuea Creek which flows southwest into the Klastline River.<ref>{{BCGNIS|7183|Morchuea Creek|access-date=2023-09-27}}</ref> Konthil Creek is the second named right tributary which flows southwest into the Klastline River just northwest of Iskut.<ref>{{BCGNIS|6243|Konthil Creek|access-date=2023-09-27}}</ref> The third right tributary is Grass Creek which flows south into the Klastline River.<ref>{{BCGNIS|12407|Grass Creek|access-date=2023-09-27}}</ref> Jokerslide Creek, the fourth named right tributary, flows southwest into the Klastline River.<ref>{{BCGNIS|12017|Jokerslide Creek|access-date=2023-09-27}}</ref> The fifth named right tributary, Cheeny Creek, flows southwest into the Klastine River east of Telegraph Creek.<ref>{{BCGNIS|4990|Cheeny Creek|access-date=2023-09-27}}</ref> The sixth named right tributary is Detiaten Creek which flows west into the Klastline River just northeast of Telegraph Creek.<ref>{{BCGNIS|14547|Detiaten Creek|access-date=2023-09-27}}</ref>

Only three left tributaries of the Klastline River are named. The first one is Tsazia Creek which flows north into the Klastline River.<ref>{{BCGNIS|23838|Tsazia Creek|access-date=2023-09-27}}</ref> [[Kakiddi Creek]], the second named left tributary, flows north into the Klastline River.<ref>{{BCGNIS|2974|Kakiddi Creek|access-date=2023-09-27}}</ref> The third named left tributary is Buckley Creek which flows northeast into the Klastline River east of Telegraph Creek.<ref>{{BCGNIS|1633|Buckley Creek|access-date=2023-09-27}}</ref>

The roughly {{Convert|50|km|mi|adj=mid|-long|abbr=on}} 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 {{Convert|25|km|mi|abbr=on}} 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 {{Convert|10|km|mi|abbr=on}} and then crosses the river at the northern end of Mount Edziza Provincial Park. From there, the Klastline River Trail traverses west for about {{Convert|15|km|mi|abbr=on}} to the northeastern end of Buckley Lake where it meets with the Buckley Lake Trail and Buckley Lake to Mowdade Lake Route junction.<ref name="mapbook">{{cite book|editor-last1=Mussio|editor-first1=Russell|title=Northern BC Backroad Mapbook|publisher=Mussio Ventures|pages=88, 89|year=2018|isbn= 978-1-926806-87-7}}</ref>

==Geology== The Klastline River has been repeatedly blocked by lava flows from the adjacent [[Mount Edziza volcanic complex]]. In the [[Pleistocene]], massive [[basalt]] flows from at least three eruptive centres on the northern side of the volcanic complex entered the narrow valley of the Klastline River from Kakiddi Valley, temporarily blocking it to form a large shallow lake upstream. The main source of these lava flows was [[Klastline Cone]] and are assigned to the [[Klastline Formation]]. Erosional remnants of the Klastline lava flows form small [[butte]]s and buttresses along Klastline Valley.<ref name="Souther">{{cite report|last1=Souther|first1=J. G.|author-link1=Jack Souther|title=The Late Cenozoic Mount Edziza Volcanic Complex, British Columbia|work=[[Geological Survey of Canada]]|publisher=Canada Communication Group|series=Memoir 420|year=1992|pages=22, 27, 191, 213, 214, 217, 222, 224, 225|isbn=0-660-14407-7|doi=10.4095/133497|doi-access=free}}</ref>

At least three [[cinder cone]]s of the Mount Edziza volcanic complex blocked the Klastline River during the [[Holocene]]. [[Moraine Cone]] produced a northeasterly lava flow that temporarily blocked both Kakiddi Creek and the Klastine River. Subsequent etching of new channels around or through the flows by both streams has exposed beds of [[lacustrine]] [[silt]] where lava-dammed lakes ponded upstream. Lava flows from [[Kana Cone]] also temporarily blocked the Klastline River and may have travelled Klastline Valley as far west as the Stikine River. The Klastline River was forced to establish a new route along the northern valley wall where it still flows to this day. [[Williams Cone]] produced a more than {{Convert|10|km|mi|adj=mid|-long|abbr=on}} lava flow into Klastline Valley where its distal lobe formed a temporary dam across the Klastline River. All three cinder cones and associated lava flows are assigned to the [[Big Raven Formation]].<ref name="Souther"/>
