## Five questions with verified answers

### Do the trovants really grow?

**Verdict: They do not grow like living things**

The Costești trovants are sandstone concretions formed about 6 million years ago, as groundwater cemented the sands with calcium carbonate; the blocks reach over 4 metres. The impression that they appear after rain comes from erosion: water washes the sand away and uncovers the blocks, just as wind and rain excavated the shapes at Ulmet.

### Is Lake Ursu heated by a thermal spring?

**Verdict: No; the sun heats it**

The deep water reaches 35–40°C through a solar greenhouse effect: the thin layer of fresh water at the surface never mixes with the dense salt water below and traps the sun's heat. That is why bathing is allowed only at certain hours of the day, so the layers are not stirred.

### Do the mud volcanoes erupt lava?

**Verdict: No; the cones are cold**

The Berca cones are cold: natural gas rising from 3,000 metres down carries mud to the surface, where the air dries it into cones up to 6 metres tall. The 30 hectares stay bare of vegetation, furrowed by erosion gullies.

### Does the air in the Pucioasa cave kill instantly?

**Verdict: Only below the marked line**

The cave breathes out about 3,000 m³ of CO₂ and hydrogen sulphide a day; the gas, heavier than air, settles on the cave floor, and the yellow sulphur crystals mark the lethal level, the 'line of death'. The danger is real only below the line marked on the walls, which visitors must strictly respect.

### Is the Hoia-Baciu forest haunted?

**Verdict: Disputed: the observations are real, the explanations are not**

The oaks bend at the trunk with no clear forestry explanation, and in the Round Glade trees refuse to grow. In 1968 unusual light phenomena were photographed above the glade. Beyond these recorded observations, the forest remains a subject for documentaries, not for conclusions.

## Subterranean and karst depths

Near Mangalia sits a cave whose air is toxic to humans, where 35 species live on pure chemistry without a ray of sunlight. At Chișcău you walk among 140 cave bear skeletons undisturbed for 15,000 years. At Scărișoara you stand on millennia-old ice, and at Vârtop you see the petrified footprint of a Neanderthal youth. Eighteen places where the surface stays above.

- **Why it is unique**: The only intact volcanic crater lake (maar) in Central and Eastern Europe, filled with water of near-distilled purity entirely fed by rain.
- **Context**: Formed inside the crater of the Ciomatu volcanic complex, which last erupted roughly 30,000 years ago. Sitting at 946 m altitude with a maximum depth of 6.4 meters, it possesses neither inlet nor outlet streams and is nourished exclusively by atmospheric precipitation.
- **Access and visiting**: Strictly protected nature reserve. Vehicles park at the caldera rim; visitors descend to the lakeshore on foot or via electric shuttle. Swimming is prohibited to preserve water oligotrophy.

### 23. Mohos Peat Bog
- **County / Region**: Harghita (Transylvania)
- **Coordinates**: `46.1367°N, 25.9014°E`
- **Why it is unique**: Twin volcanic crater transformed into an oligotrophic peat bog 10 meters deep, sheltering carnivorous sundew plants and Ice Age tundra relicts.
- **Context**: Occupying the older caldera of Mount Ciomatu, the bog spans 80 hectares. Beneath cushions of Sphagnum moss lies a 10-meter-thick peat layer saturated with acidic water. It shelters carnivorous Drosera rotundifolia (round-leaved sundew) and dwarf birch species surviving since the Pleistocene glaciation.
- **Access and visiting**: Visits are strictly guided along an elevated wooden boardwalk over the fragile peat. Access begins from the main parking area shared with Lake Sfânta Ana.

### 24. Pucioasa Sulfur Cave Mofette (Torja)
- **County / Region**: Covasna (Transylvania)
- **Coordinates**: `46.1219°N, 25.9619°E`
- **Why it is unique**: Europe's largest natural mofette: a volcanic cavern discharging 3,000 m³ of pure CO₂ and sulfur daily, marked by a visible boundary called 'the death line'.
- **Context**: Perched on Mount Pucioasa at 1,052 m altitude near Balvanyos, the cavern was historically used for sulfur extraction. Heavy CO₂ gas settles in dense layers along the floor. Yellow sulfur crystals on the walls demarcate the exact surface of the lethal, oxygen-deprived gas layer.
- **Access and visiting**: Accessible via a 20-minute hiking trail from Băile Balvanyos. Visitors can take standing dry CO₂ therapeutic gas baths; bending below the marked yellow wall line is strictly prohibited.

### 25. Bear Lake (Lacul Ursu)
- **County / Region**: Mureș (Transylvania)
- **Coordinates**: `46.5964°N, 25.0864°E`
- **Why it is unique**: The largest heliothermal lake on Earth and the only one in Europe: a freshwater lens effect traps solar heat in the dense brine beneath, reaching 35–40°C.
- **Context**: Formed in 1875 following a sinkhole collapse over salt beds, the lake spans 4 hectares. Heliothermy occurs because a thin layer of incoming fresh river water floats unmixed above hyper-saline dense brine, acting as a greenhouse lens that prevents heat dissipation.
- **Access and visiting**: Developed as an open-air spa open June through September. Bathing is restricted to controlled midday hours to preserve thermal layering.

### 26. Detunata Goală & Flocoasă Basalt Pillars
