In April 1983, the town of Thistle, Utah, experienced a devastating landslide brought on by heavy rains and rapidly melting snow. The water main filled a part of the embankment, turning it into a kind of loose sludge that eventually gave way and slid down towards the Carinya lodge. The landslide in Thistle, Utah, (1983) caused over $200 million in damages and property loss. It had a slide mass of 55 million cubic meters (compared to an estimated 10 million cubic meters during the Oso, Washington event). The eco-nomic loss associated with the Thistle landslide was several hundred million dollars (in 1984 dollars), which included In 1983, the costliest landslide in US history was triggered. The landslide was caused by a combination of a leaking water main and problems with the construction of the Alpine Way road, which was built atop uncompacted fill. Spread. AMERICAN SOCIETY OF CIVIL ENGINEERS ASCE LIBRARY. The Little Town Of Thistle Utah Disappeared In A Mudslide - OnlyInYourState The landslide dammed the Spanish Fork River drowning the town of Thistle with the 200-foot-deep temporary Thistle lake. The landslide is still active; It occurs as a result of mechanical weathering, earthquakes, and the force of gravity. I n 1983 the town of Thistle, Utah, known to many highway travelers as the small community where both the Spanish Fork River and nearby U.S. highways branch, was eliminated by the most costly landslide on record in the United States.. Thistle was located at the triple junction of transportation systems leading south to Sanpete County, east to the coal counties of Carbon and Emery and Abstract In mid-April, 1983, an old landslide near Thistle, Utah, began to move, and within days had blocked Spanish Fork Canyon. The landslide was caused by a combination of a leaking water main and problems with the construction of the Alpine Way road, which was built atop uncompacted fill. A recent publication done by the Utah Geologic Survey reports the occurrence of over 22,000 landslide activities throughout the state over the recent geologic past. It is stated to have been the most costly landslide in the United States History at a 21st century cost of up to $922 million. Debris flows (commonly referred to as mudflows or mudslides) and rock falls are examples of common landslides types. The slide was over 200 View is southeast looking into Lake Fork. Furthermore, the Thistle Landslide and immediate area has continued to move intermittently since the 1983 wet year. Minor mudslides (earth flows) periodically occur near its flanks and head. Following a wet winter, almost the entire slide (except for the dam section) moved in spring of 1998. Lake Thistle was created by the landslide. As the slide's movement continued, construction crews gradually converted the toe of the slide into an earth-filled dam--Thistle dam--that impounded northwest-flowing Spanish Fork River. It was roughly a mile long. New railroad tracks have been laid on the left. the small town of Thistle. Note beginning of the railroad tunnel at lower left center. Resource Download and Tools. The primary cause of a landslide is the influence of gravity acting on weakened materials that make up a sloping area of land. Landslides take the lives of thousands of people across the world. The deposition was one of many read during Monday's proceedings in a lawsuit filed by Thistle residents against the Denver and Rio Grande Western Railroad.

It happens on flat terrain and gentle slopes and can occur because of softer material. Area to the left of the toe of the slide is a buttress formed by the Nugget Sandstone and the Twin Creek Limestone. Causes of Landslide. When it finally stopped and abutted against the opposite canyon wall in Spanish Fork Canyon, Utah County, it dammed the Spanish Fork River; the resulting Thistle Lake submerged the town of Thistle.

Witkind represents a specific, individual, material embodiment of a distinct intellectual or artistic creation found in Indiana State Library. Falls: Falls are sudden movements of loads of soil, debris, and rock that break away from slopes and cliffs. Tourism in the area, particularly in-state tourism, was greatly reduced due to lack of access. The main types of movement are falls, topples, slides, and flows. What are the types of landslides? Depositions from The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows. Below is information pertaining to the Thistle, Utah landslide and the Cedar Hills, Utah landslide (active). What made Thistle into a ghost town was a massive landslide that occurred in April, 1983. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. There have been several major landslide events in Utah county over the last 25 years which have caused hundreds of millions of dollars in damages and property loss. The Thistle Landslide. Heavy snowfall, combined with a warm, wet spring triggered the landslide which eventually reached speeds of up to 3.5 feet per hour. Due to market conditions and the Thistle landslide, coal production dropped nearly 30 percent in 1983. To the south, the blockage of Highway 89 and the rail line hurt coal companies, turkey and feed operations, and gypsum, cement, and clay shipments. The landslide, a reactivation of an estimated 22 multiplied by 10**6 m**3 of old landslide debris, blocked Spanish Fork Canyon and thereby created a lake more than 50 m deep.

The slide was over 200 feet thick, 1000 feet wide, and over one mile long. The water main filled a part of the embankment, turning it into a kind of loose sludge that eventually gave way and slid down towards the Carinya lodge. Toe of slide gradually being thickened to form earth filled dam. A classic morphological cause of landslides is erosion, or weakening of earth due to water. Just to the right of the railroad tunnel, near the top of the dam, is part of a spillway tunnel designed to prevent the lake Rock and soil samples involved in the Thistle landslide were collected and studied. The main rock types are sandstone and limestone, and the soil is composed almost exclusively of quartz sand grains and clay minerals (illite). Previous strength studies performed on course-grained sandstone make it easy to see why the landslide was triggered. 1983 Thistle landslide was 100 times larger than North Salt Lake slide. The Thistle landslide resulted in Utahs first U.S. Presidential Disaster. The landslide occurred on December 15, 1999, in the state of Vargas, Venezuela. Landslides are classified by their type of movement. the landslide damage, includ-ing re-routing the highway and railroad, was several hundred million dollars.

It is a kind of landslide when a piece of the rock slides downwards and gets separated from it. The largest landslide in modern U.S. history (in terms of volume) was most likely one that occurred just last year in Bingham Canyon outside of Salt Lake City, Utah on April 10, 2013. After the re-sulting lake was drained and sediment was shown to have partially buried the town, Thistle was abandoned. Landslides are caused by various factors, which are mentioned below: It can be caused because of heavy rain. A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. In the aftermath of the disaster, this paper examines the landslide event, the history of movement, geological conditions at the site, and the Landslide Case Study 1THISTLE, UTAH 1983 WILL PARKIN This item is available to borrow from 1 library branch.
