The Inhini River is a tributary of the Iskut River in the northwest part of the province of British Columbia, Canada, in Cassiar Land District.[4][7] From its source in the glaciers of Simma Mountain and Mount Rastus, the Inhini River flows north for about 25 km (16 mi)[5] to the Iskut River just east of the Iskut's confluence with the Stikine River.

The Inhini River's watershed covers 135 km2 (52 sq mi),[6] and its mean annual discharge is an estimated 12.4 m3/s (440 cu ft/s).[6] The river's watershed's land cover is classified as 26.2% shrubland, 23.7% barren, 20.7% snow/glacier, 16.2% conifer forest, and small amounts of other cover.[6]

The mouth of the Inhini River is located about 57 km (35 mi) east-northeast of Wrangell, Alaska, about 130 km (81 mi) northwest of Stewart, British Columbia, and about 135 km (84 mi) south of Telegraph Creek, British Columbia.[8][3]

The Inhini River is in the traditional territory of the Tlingit, specifically the Shtax'héen Ḵwáan, commonly known as the Stikine River people.[9][10] It is also in the asserted traditional territory of the Tahltan First Nation and Iskut First Nation, of the Tahltan people.[11]

Geography

The Inhini River originates in two forks near the border of Alaska. The longer eastern fork flows from the glacial meltwaters of Mount Rastus[12] and Simma Mountain,[13] close to the source of Simma Creek,[14] a tributary of the Craig River. This fork flows for about 7 km (4.3 mi) before being joined by the west fork, which flows from the glacial meltwaters of Mount Fawcett,[15] an Alaska–British Columbia boundary peak.

The mainstem Inhini River flows north between Inhini Mountain and Mount Whipple,[16][17] then between Fizzle Mountain and Snowy Mountain,[18][19] collecting a number of unnamed tributary streams. It becomes a braided river after entering the floodplain of the Iskut River. The Inhini River empties into a side channel of the highly braided Iskut River about 15 km (9.3 mi) east of the mouth of the Iskut, where it joins the Stikine River a few kilometres upriver of the Alaska boundary.[8][3][20]
