Kamchatka’s Valley of Death is a silent killer: near a volcano, toxic gases – hydrogen sulfide and carbon dioxide (H₂S and CO₂) – ooze from fissures like the breath of a sleeping dragon. Any creature that ventures in receives a «black mark» - death claims it within minutes. This eerie place feels like a myth come to life. The air here is thick with poisonous fumes, and their concentration is so high that even large animals cannot escape in time. Scientists see this landscape as a living echo of Earth’s ancient volcanic past, helping them uncover the secrets of our planet’s fiery history. 1982: hydrogen cyanide & cyanogen chloride found in Valley of Death air. Minimal amounts → respiratory paralysis + cardiac arrest.

| 3 |  +3Dallol Volcano is one of the most extraordinary and extreme places on Earth 🇪🇹
📍Located in Ethiopia's Danakil Depression, it is the world's lowest subaerial volcano. It may not be tall, but beauty isn't measured by height. Dallol is famous for its colorful hydrothermal springs, highly acidic pools, and spectacular salt formations in shades of yellow, green, white, and orange.
🌋 These vivid colors are created by chemical reactions between hot, mineral-rich fluids and salt deposits, making Dallol one of the most unique geothermal landscapes on the planet. | 98 |

🤍 Uchkoshkon Tin Ore Deposit: A Key Discovery
A prominent geologist and science organizer, Apas Bakirov made a major contribution to geological science. He founded a unique scientific school focused on the interrelations between geological processes, metamorphism, and tectonics.
He served as the scientific head of this metamorphic research direction — the only one of its kind in Central Asia. His achievements have been recognized by the global geological community. | 52 |
| 5 |  +1☕️ A cappuccino river? Not quite…
Not quite. This is one of the world's most fascinating natural phenomena.
📍Near the Brazilian 🇧🇷 city of Manaus, the dark waters of the Rio Negro meet the muddy Solimões River. Surprisingly, they do not mix immediately. Instead, they flow side by side for about 7 km (4.3 miles), creating a sharp boundary known as the Meeting of Waters.
The reason lies in the rivers' different physical properties. They have different temperatures, densities, flow velocities, and sediment loads.
The Solimões is about 6°C colder, flows much faster, and carries large amounts of suspended sediment, giving it its muddy brown color. The Rio Negro is warmer, slower, and rich in dissolved organic matter, which gives it its distinctive dark appearance. | 79 |
| 6 |  Answer: $3–5 per carat ⬅️
63.74‑carat charoite cabochon was priced at AUD 177, which equals approximately $3–5 per carat
🤍Charoite is affordable despite its rarity because it is abundant at the single deposit and is usually cut as opaque cabochons. | 63 |
| 7 | ⚖️ What is the estimated price of a gem‑quality charoite cabochon per carat?🤩
| 63 |
| 8 |  Charoite — a rare silicate mineral known for its striking purple colour with characteristic swirling patterns
🤩It was first discovered in the 1940s in the Murun Massif in eastern Siberia, along the Chara River, but remained unknown to the outside world for decades
📍The only known deposit of charoite is located in Russia (Sakha Republic). Outside Russia, this mineral has never been found.
🤍The unique beauty of charoite was recognised by Soviet geologists in the 1950s, but the deposit was kept secret for many years. Soviet authorities valued charoite for its decorative potential and used it in stone‑cutting art. Large polished slabs of charoite can still be seen in some interiors built during the late Soviet period. | 69 |

| 10 |  +4Would you try pizza baked on an active volcano? 🌋🍕
In Guatemala, you can do exactly that on 📍Pacaya Volcano.
Instead of a traditional oven, the pizza is cooked using the intense heat from volcanic rocks and fresh lava. The cooks wear protective goggles and heat-resistant gloves—otherwise, they might end up roasting alongside the pizza.
And yes, the risk is real. Pacaya is an active volcano, and unexpected bursts of lava and volcanic gases can happen at any time.
If you're feeling adventurous, you can visit the volcano as part of a guided tour. The experience typically costs around $200 and includes the chance to watch your pizza bake on one of the hottest "ovens" on Earth. | 271 |
| 11 |  The Russian "Mummy" Paint. Was it really made from ancient mummies?
Mummy Brown was a historical pigment made by grinding the dried remains of ancient Egyptian mummies together with the resins used in the embalming process. From the 16th century until the early 20th century, artists in Europe used this unusual pigment to create warm, transparent brown tones.
The practice became especially popular during the Victorian era, when the trade in Egyptian antiquities was booming. As demand for the pigment grew, countless mummies were bought, ground into powder, and sold to artists.
❌ BUT The famous artist's pigment made from Egyptian mummies was not the same as the Russian paint called "mummy."
The confusion comes from the name.
🤍 In the ♥️♥️th and ♥️♥️th centuries, Russian builders and craftsmen used a red mineral pigment known as mummy. Unlike the British Mummy Brown, it contained no human remains. Instead, it was made from naturally occurring iron-rich clay, where tiny particles of hematite (Fe₂O₃) gave the pigment its deep red color.
The paint was inexpensive, durable, and resistant to weather, making it a popular choice for wooden houses, fences, roofs, and farm buildings across the Russian Empire.
🤍So why did both pigments have the same name?
No one knows for certain. Historians believe the Russian name was simply a traditional trade term that became attached to a local iron-earth pigment. In Britain, however, Mummy Brown literally contained powdered Egyptian mummies mixed with embalming resins—a practice that continued until the early 20th century.
Two paints. One name. Completely different origins. | 93 |
| 12 | What do you think? 🤔 | 87 |
| 13 |  Have you ever wondered how people painted houses before modern chemical factories?
In the 18th century, builders in Russia used a durable red pigment known as "mummy." Despite its unusual name, it had nothing to do with Egyptian mummies.

🤍 Yareta — а flowering relative of carrots and parsley, surviving at an altitude of 5 km.
To protect itself from cold, wind, and sun, thousands of stems squeeze into a tight dome that traps heat and moisture. Yareta grows one millimetre per year. Some are two to three thousand years old. | 118 |

The Museum of the Karpinsky Geological Institute houses more than ♥️♥️♥️♥️ mineral specimens. But have you ever wondered what a "deep clean" looks like at the Geological Museum?
We're taking you behind the scenes to show you exactly how it happens.
Every last Tuesday of the month, when the museum is closed to visitors, the staff transforms into a team of professional cleaners. First, they have to open every single display case – and there are ♥️♥️♥️ of them! Armed with cleaning supplies, the team meticulously goes through every shelf and every exhibit.
And that's how the cleaning passes by, quietly and unnoticed – so that when you visit the museum, you can see the exhibits in all their glory. | 118 |
| 18 |  +4In 1964, a powerful geyser was created by accident during well drilling in the 📍Black Rock Desert in northern Nevada
Boiling water brought minerals to the surface, which formed a pedestal‑like mound with a small fountain on top. The geyser is covered in thermophilic algae that thrive in hot, wet environments. It is these algae that give the geyser its many shades of green and red, striking visitors with their bright colours.
🏜️The geyser sits on a private ranch and has an owner. It is hidden from view by a tall fence and locked gates with spikes. Occasionally, tourist groups are allowed onto the protected property, but most of the time you can only admire it from the road. | 97 |

| 20 |  Answer: $20,000 – $50,000
This spectacular 15.91-carat black opal pendant was priced by an Australian luxury jeweller in 2025 at $20,000–$50,000 range.
🤍Why such a high price?
The unique dark body tone of black opals serves as a dramatic backdrop for brilliant flashes of colour. The most valuable specimens display a full spectrum of rainbow colours with clear, distinct patterns — something that geological conditions at Lightning Ridge produce better than anywhere else. The vibrant play-of-colour is created by an optical effect called diffraction: microscopic silica spheres inside the stone break white light into individual colours, creating a dazzling kaleidoscope of shifting hues. | 96 |
