- The Suiattle River (/suːˈætəl/ soo-AT-əl) is a river in the northern Cascade Mountains of western Washington, United States. It is a tributary of the Sauk River and by extension the Skagit River. Its source is located between Suiattle Glacier and Honeycomb Glacier on Glacier Peak, at an elevation of around 7,000 ft (2,100 m) above sea level. It descends through a 60-mile (97 km) course, lying mainly within the Mount Baker–Snoqualmie National Forest. It meets the Sauk northeast of Darrington, Washington, at an elevation of 400 ft (120 m). Snowmelt from Chocolate and Dusty Glacier gives the river silty water, with a suspended load over twice that of the upper Sauk or adjacent White Chuck.
- Basalt (Wikipedia)
Basalt (UK: /ˈbæsɔːlt, -əlt/; US: /bəˈsɔːlt, ˈbeɪsɔːlt/) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars.
