The Ankylosaur bones dated during the Cretaceous Period from Carlsbad, California, which was discovered in Point Loma Formation mudstone containing oyster shells and a shark tooth, perished near a river or estuary and the swift waters carried the body out to sea and buried it in the sediments sdnhm.org/exhibitions/fos…
Not only is Lake Baikal the world's largest lake by volume (22–23% of the world's fresh surface water) and the deepest (1,642 m / 5,387 ft), but it also has over 7 km of sediment, placing the rift floor some 8–11 km (5.0–6.8 mi) below the surface, making it the deepest continental rift on Earth. wikipedia.org/wiki/Lake_B…
The white area in the center of ice cubes is a buildup of impurities, mostly sediment and trapped air bubbles. Because freezing starts from the outside in, these materials are pushed to the center of the cube while the pure areas remain clear. kdlt.com/2015/04/09/what-…
Egyptians and Sumerians invented straws 7,000 years ago to use for sipping beer. Created from natural products, the straws were used to separate sediment from beer as the beer-making process used to leave unwanted elements in the drink egypttoday.com/Article/4/…
Roughly 500 Million Tons of Sediment are Deposited in the Gulf of Mexico by the Mississippi River Every Year earthobservatory.nasa.gov…
You’re supposed to flush your water heater every 6 months to avoid calcification and hardening of sediments at the bottom forcing you to replace the water heater if it’s neglected. directenergy.com/blog/how…
During the siege of Tyre in 332 BC, Alexander the Great ordered the construction of a kilometre-long causeway between the island and the Lebanese mainland that, in addition to facilitating the breaking of the siege, collected sediment and turned the island into a peninsula. en.wikipedia.org/wiki/Sie…
Today I learned that in 2014 the US finished it’s largest dam removal in history on the Elwha river in Washington state. The once dammed reservoir of over 100 years, now flows freely and is once again booming with salmon, birds, moose, and even new beaches being formed by sediment! relay.nationalgeographic.…
6,000 years ago, extensive copper mining operations in North America polluted the Great Lakes region. Isle Royale, a national park found in the State of Michigan, features high levels of copper, lead, and potassium in the ancient sediments. eos.org/articles/miners-l…
There are a billion missing years in earth's rock layers -- one theory is that Snowball Earth, where miles of ice eroded those rock layers and sent the sediment into the oceans where they were plunged back into the mantle to be recycled -- there are also no fossil layers before this period eos.org/articles/erasing-…
The Congo Canyon has the strongest known turbidity currents in the world. These currents, which are essentially underwater avalanches, occur when sediment-rich waters flow rapidly down the canyon walls at speeds of up to 3.5 meters/second, and have been known to destroy telegraph cables. en.wikipedia.org/wiki/Con…
A Japanese chemical company once polluted a bay so thoroughly that some sediment contained up to 2 kg of mercury per ton. This concentration made mining economically viable, and eventually the company set up a subsidiary to do just that. en.wikipedia.org/wiki/Min…
Albert Einstein's son, Hans, was a famous hydraulic engineering professor who developed important equations for sediment transport in rivers. When reporters asked Albert what he thought of his son's career, he replied, "He is working on a more difficult problem" books.google.ca/books?id=…
The moldy looking residue at the bottom of the inside of Mountain Dew bottles is "fruit juice sediment" mlive.com/food/index.ssf/…
At a US nuclear test site in middle of the Pacific, radioactive waste was buried and covered with a concrete dome. Cleanup was so poor that the dome fails American standards for landfills for household trash and radiation inside the dome is dwarfed by the radiation in the sediments outside it. nytimes.com/2014/12/04/op…
The Russian city of Norilsk, due to industrial nickel smelting operations, has such severe pollution that ponds within the city are dredged to recover the valuable heavy metals that accumulate in their bottom sediment nytimes.com/2007/07/12/wo…
DNA from dirt. Scientists can determine which ancient animals and plants existed in an area by extracting DNA from as little as 2 grams of sediment. youtube.com/watch?v=_9Kd_…

That, after Mt. St. Helens erupted in 1980, so much ash and sediment flowed down that it was clogging the great Columbia River, so the US Army Corps of Engineers built a huge sediment retention dam to catch it. It's full. They may need another one soon. en.wikipedia.org/wiki/Tou…

The rocks in Hamelin Pool are actually growing. They are Stromatolites made of sediment and microbes and grow about a centimeter a year. en.wikipedia.org/wiki/Ham…
The Niagra River creates so much erosion that within 50,000 years Niagra Falls will cease to exist. It's this sediment that gives the falls the green water they are famous for. en.m.wikipedia.org/wiki/N…
Drinking water treatment plants can no longer return filtered sediments back to the same water body they came from nab.usace.army.mil/Missio…
Albert Einstein's oldest son, Hans, wrote a thesis on sediment transportation and till this day it is considered the definitive work on the subject. en.wikipedia.org/wiki/Han…
A 7.5‑magnitude earthquake struck Yellowstone National Park in 1959. The quake triggered a huge landslide, sediment dammed the river and created a new lake. en.wikipedia.org/wiki/Yel…
For the construction of the Brooklyn Bridge, upside-down boxes (caissons) were placed underwater and pumped with air so workers could dig the sediment until the caissons sank to the bedrock. The entire bridge still sits on the original, 145 year-old caissons. en.wikipedia.org/wiki/Bro…
Lake Karachay in Russia is so radioactive that when scientists measured the activity in the lake in 1990 they found that the radiation would give you a lethal dose in an hour. The sediment bed is almost entirely high level radioactive waste. en.wikipedia.org/wiki/Lak…
Uluru (Ayes Rock) in Australia is compressed sediment from eroded mountains that was turned on its side by tectonic activity. From one side to the other, it is a sediment timeline spanning 50 million years. ayersrockresort.com.au/ge…
What many called New Zealand's greatest natural wonder (the Pink and White Terraces) totally disappeared in a volcanic eruption in 1883, but may still exist under water and layers of sediment. en.wikipedia.org/wiki/Pin…
