A sharply pyramidal peak rising in isolation at the border of Switzerland and Italy.
The Matterhorn is one of the most instantly recognizable mountains in the world, a sharply pyramidal peak rising in isolation at the border of Switzerland and Italy, above the twin Alpine communities of Zermatt in the canton of Valais and Breuil-Cervinia in Italy’s Aosta Valley.
Stalactites covering 1.4 ha (3.5 acres) of a cavern have been harnessed to produce musical tones when struck with rubber-tipped mallets linked to a keyboard.
The Great Stalacpipe Organ is one of the most unusual and fascinating musical instruments in the world. Located in the Luray Caverns of Virginia’s Shenandoah Valley, this instrument uses natural limestone stalactites as its tone generators, making it the largest musical instrument in terms of physical space—its sound can be heard throughout the 64-acre cave.
Microscopic, metallic spheres were discovered during a 2023 oceanic expedition.
The BeLaU spherules are a collection of microscopic, metallic spheres enriched in beryllium (Be), lanthanum (La), and uranium (U), discovered during a 2023 oceanic expedition led by Harvard astrophysicist Avi Loeb. This mission aimed to locate remnants of a meteor, designated IM1, which entered Earth’s atmosphere in 2014 and was hypothesized to be of interstellar origin
Mystery at Blind Frog Ranch (Discovery Channel) visited the Serpent Mound in Ohio and were shown shatter cones from the meteorite impact that happened there.
Shatter cones are distinctive geological features that serve as compelling evidence of hypervelocity impact events, such as those caused by meteorites. They are cone-shaped, striated rock structures formed under extremely high pressures, typically exceeding 2 GPa (gigapascals), in the moments following an impact.
In Season 4, Episode 4 (“The Skull”) of the Discovery series Mystery at Blind Frog Ranch, they find what might be an abandoned open pit mine.
Open-pit mining, also known as open-cut mining, is a surface mining technique characterized by the excavation of large pits to extract minerals and ores. This method is widely used when deposits are found close to the surface and is applicable for a range of resources, including coal, gold, copper, and iron.
The meteorite was found in a region known for its arid climate, which helps preserve such space rocks.
The El Ali meteorite, Nightfall, is a notable space rock that gained attention due to its significant size and the circumstances surrounding its discovery. Found in the region of El Ali in Somalia, this meteorite is classified as a type of chondrite, which is one of the most common types of meteorites.
The longest mountain range on Earth.
The Mid-Atlantic Ridge (MAR) is a continuous mountain range running down the center of the Atlantic Ocean, marking the boundary between the North American and Eurasian tectonic plates to the west and the South American and African plates to the east. This underwater mountain range extends for about 10,000 miles and is the longest mountain range on Earth.
Sunstone is also known as “heliolite” and more commonly “aventurescent feldspar.” It is cut into cabochons, beads, and small sculptures. The most transparent pieces are used to produce faceted stones.
Sunstone, aventurescence[1] feldspar, is a captivating gemstone known for its captivating play of colors, has gained prominence in the world of gemology. This post delves into the physical properties of sunstone, discusses the controversy surrounding andesine, and focuses on the unique characteristics of Oregon sunstone.
A land formation, less extensive than a plateau, having steep walls and a relatively flat top and common in arid and semiarid parts of the southwestern U.S. and Mexico.
Mesas are geological landforms characterized by flat-topped, steep-sided hills or mountains. They typically have a small, relatively flat summit area that stands above the surrounding terrain, often in the form of a plateau. Mesas are commonly found in arid or semi-arid regions and are a result of various geological processes. Mesas are formed through a combination of erosion and uplift.
No Rock Quarry! Well, maybe.
I was driving through Carroll County[1], Georgia the other day and saw this sign. On previous trips, a multitude of houses was displaying “No Rock Quarry” signs. I have finally decided to see just what is going on in this county.
