Dease Lake in the context of "Walkout Creek"

Mess Creek, formerly known as Mestua, is a tributary of the Stikine River in northwestern British Columbia, Canada. It flows north and northwest for about 110 km (68 mi), through a lake and a gorge to join the Stikine River, which in turn flows southwest across the Canada–United States border into Alaska where it empties into various straits of the Inside Passage. The northern half of Mess Creek forms a western boundary of Mount Edziza Provincial Park which lies within the traditional territory of the Tahltan people.

Mess Creek's watershed covers 2,330 km (900 sq mi) and its estimated mean annual discharge is 59.3 m/s (2,090 cu ft/s). The mouth of Mess Creek is located about 3 km (1.9 mi) southwest of Telegraph Creek, about 73 km (45 mi) west of Iskut and about 94 km (58 mi) southwest of Dease Lake in Cassiar Land District. Mess Creek's watershed's land cover is classified as 38.7% conifer forest, 25% barren, 15.9% shrubland, 10% snow/glacier, 8.3% herbaceous and small amounts of other cover.

Kakiddi Creek is a tributary of the Klastline River in northwest part of the province of British Columbia, Canada. It flows north about 35 km (22 mi) through two lakes in a broad hummocky lowland to join the Klastline River, which in turn is a tributary of the Stikine River. Kakiddi Creek forms the northeastern boundary of Mount Edziza Provincial Park which lies within the traditional territory of the Tahltan people.

Kakiddi Creek's watershed covers 709 km (274 sq mi) and its estimated mean annual discharge is 11.5 m/s (410 cu ft/s). The mouth of Kakiddi Creek is located about 25 km (16 mi) west of Iskut, 44 km (27 mi) east of Telegraph Creek and about 77 km (48 mi) south-southwest of Dease Lake. Kakiddi Creek's watershed's land cover is classified as 46.6% conifer forest, 17.4% barren, 15.4% shrubland, 11.2% herbaceous, 5.4% snow/glacier, and small amounts of other cover.

The Mount Edziza volcanic complex (/ədˈzaɪzə/ əd-ZY-zə; abbreviated MEVC) is a group of volcanoes and associated lava flows in northwestern British Columbia, Canada. Located on the Tahltan Highland, it is 40 kilometres (25 miles) southeast of Telegraph Creek and 85 km (53 mi) southwest of Dease Lake. The complex encompasses a broad, steep-sided lava plateau that extends over 1,000 km (390 mi). Its highest summit is 2,786 metres (9,140 feet) in elevation, making the MEVC the highest of four large complexes in an extensive north–south trending volcanic region. It is obscured by an ice cap characterized by several outlet glaciers that stretch out to lower altitudes.

The MEVC consists of several types of volcanoes, including stratovolcanoes, shield volcanoes, cinder cones and lava domes. These volcanoes have formed over the last 7.5 million years during five cycles of magmatic activity which spanned four geologic epochs. Volcanic eruptions during these magmatic cycles produced a wide variety of volcanic rocks that comprise 13 geological formations. The most recent eruptions took place in the last 11,000 years but none of them have been precisely dated. Current activity occurs exclusively in the form of hot springs which exist along the western side of the volcanic complex. Future eruptions are likely to impact local streams and cause wildfires.
