Mess Creek in the context of "Big Raven Plateau"

Walkout Creek is a tributary of Raspberry Creek, which in turn is a tributary of Mess Creek, part of the Stikine River watershed in northwest part of the province of British Columbia, Canada. It flows generally west for roughly 12 km (7.5 mi) to join Raspberry Creek about 5 km (3.1 mi) east-southeast of Raspberry Creek's confluence with Mess Creek. Walkout Creek's watershed covers 80.9 km (31.2 sq mi) and its mean annual discharge is estimated at 2.26 m/s (80 cu ft/s). The mouth of Walkout Creek is located about 44 km (27 mi) southeast of Telegraph Creek, about 38 km (24 mi) southwest of Iskut and about 108 km (67 mi) south-southwest of Dease Lake. Walkout Creek's watershed's land cover is classified as 34.2% barren, 25.1% shrubland, 21.5% herbaceous, 17.7% conifer forest, and small amounts of other cover.

Walkout Creek is in Mount Edziza Provincial Park which lies within the traditional territory of the Tahltan people.

Mount Edziza (/ədˈzaɪzə/ əd-ZY-zə; Tahltan: Tenh Dẕetle [ten̥ ˈdðetle]) is a volcanic mountain in Cassiar Land District of northwestern British Columbia, Canada. It is located on the Big Raven Plateau of the Tahltan Highland which extends along the western side of the Stikine Plateau. Mount Edziza has an elevation of 2,786 metres (9,140 feet), making it the highest point of the Mount Edziza volcanic complex and one of the highest volcanoes in Canada. However, it had an elevation of at least 3,396 m (11,142 ft) before its formerly cone-shaped summit was likely destroyed by a violent eruption in the geologic past; its current flat summit contains an ice-filled, 2-kilometre-in diameter (1.2-mile) crater. The mountain contains several lava domes, cinder cones and lava fields on its flanks, as well as an ice cap containing several outlet glaciers which extend to lower elevations. All sides of Mount Edziza are drained by tributaries of Mess Creek and Kakiddi Creek which are situated within the Stikine River watershed.

Mount Edziza consists of several types of volcanic rocks and at least six geological formations that formed during six distinct stages of volcanic activity. The first stage 1.1 million years ago produced basalt flows and a series of rhyolite and trachyte domes. Basalt flows and smaller amounts of trachyte, tristanite, trachybasalt, benmoreite and mugearite produced during the second stage about 1 million years ago comprise Ice Peak, a glacially eroded stratovolcano forming the south peak of Mount Edziza. The third and fourth stages 0.9 million years ago created basalt ridges and the central trachyte stratovolcano of Mount Edziza, respectively. Thick trachyte flows were issued during the fifth stage 0.3 million years ago, most of which have since eroded away. The sixth stage began in the last 20,000 years with the eruption of cinder cones, basalt flows and minor trachyte ejecta. Renewed volcanism could block local streams with lava flows, disrupt air traffic with volcanic ash and produce floods or lahars from melting glacial ice.
