The Green River, located in the western United States, is the chief tributary of the Colorado River. The watershed of the river, known as the Green River Basin, covers parts of the U.S. states of Wyoming, Utah, and Colorado. The Green River is 730 miles (1,170 km) long, beginning in the Wind River Mountains of Wyoming and flowing through ...
The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and Utah. The sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in the dry season.
Rockslide. A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses en masse and not in individual blocks. Note that a rockslide is similar to an avalanche because they are both slides of debris that can bury a piece of land.
Broad definitions include forms of mass movement that narrower definitions exclude. For example, the McGraw-Hill Encyclopedia of Science and Technology distinguishes the following types of landslides: fall (by undercutting) fall (by toppling) slump. rockslide. earthflow. sinkholes, mountain side. rockslide that develops into rock avalanche.
The tons of rock that fell will stay in the lake, which is between 75 and 100 feet deep. The remnants of the slide will join a few cars and some industrial debris at the bottom of the lake .
A major landslide occurred 4 miles (6.4 km) east of Oso, Washington, United States, on March 22, 2014, at 10:37 a.m. local time.A portion of an unstable hill collapsed, sending mud and debris to the south across the North Fork of the Stillaguamish River, engulfing a rural neighborhood, and covering an area of approximately 1 square mile (2.6 km 2).
The Green River, a tributary of the Colorado River, originates in Wyoming, where it flows 291 miles before entering the state of Utah. It runs for 42 miles in Colorado, and once journeying into Utah, runs another 397 miles. The confluence of the Green and Colorado Rivers is in Canyonlands National Park. [2]
