📌 Executive Summary — The Unique Essence of the Site
The Aïn Ouarka Cirque (Ramsar Site No. 1300, 2,350 hectares, classified April 6, 2003) is an open-air laboratory without global equivalent, where five extraordinary geological, hydrological and ecological phenomena converge.
Located in the heart of the Ksour Mountains (Western Saharan Atlas, Asla municipality, Nâama Province, Algeria, GPS coordinates 32°43’64”N 0°9’86”W), this site offers:
What Makes it GLOBALLY UNIQUE:
Visible Triassic diapirism (200-250 Ma) — evaporite rise creating 1,672 m amphitheater. Archimedes mechanism: light rocks 2.2 g/cm³ rise through 2.7 g/cm³ density limestone. Extremely rare in North Africa.
Pamukkale-type travertine waterfalls — 44.5°C thermal spring (+8-9°C warmer than Pamukkale 35-36°C), sulfated-sodium mineralization (5.6-6.5 g/L sodium 1800-2100, sulfate 1200-1500, chloride 800-1000, calcium 250-350, magnesium 100-150, bicarbonate 400-600, silite 50-80 mg/L), pH 7.3-7.8 alkaline, flow 2.17-3 L/s (stable year-round), conductivity 5600-6200 µS/cm.
Twin lakes contrasting ecosystems — Brackish Dzira (3-5 g/L, 8-10 ha, 0.5-1.2 m depth, Phragmites reed beds, nesting birds) vs Hypersaline Bouhaïra (45-65 g/L = Dead Sea, 15-18 ha, 2-3 m depth, 4-6 m transparency, halophilic Artemia, conductivity 95000-110000 µS/cm, pH 8.0-8.5). Only Mediterranean Ramsar site combining geothermal + extreme salinity.
Remarkable endemic biodiversity — 23% endemic flora (15 taxa strictly southwestern Oran), Warionia saharea living fossil (<1000 individuals worldwide, Asteraceae paleo-endemite tropical flora relic >10 Ma), vulnerable Pistacia atlantica (200-300 individuals, >400 years old), threatened Helianthemum lippi, endemic Crucianella hirta. Fauna: IUCN vulnerable Gazella cuvieri (15-30 local individuals, 2000-3000 worldwide 50% decline in 25 years), 500-2000 wintering pink flamingos (Nov-Feb), rare Barbary Sheep, 1.2m Desert Monitor, raptors (Eagles, Falcons), 19 bird species.
Scientifically proven thermalism — rheumatology indications (85% patients), dermatology, gynecology, ENT. Captured source thermal station. 15-21 day cure protocol, progressive phase 5-10 min (D1-3) → 15-20 min (D4-10) → 20-30 min (D11-21). Only medical geothermal Sahara site.
Strong spiritual heritage — Saint Sidi Ahmed El Medjdoub (1493-1571), Sufi mystic “enraptured in God”, tradition attributes water gushing to his Baraka. Annual Waâda Festival (December-February): Khelouet procession (D1), Sufi Dhikr prayers (D2), ritual couscous (D3), Baroud Fantasia (D4). 1000-5000 pilgrims.

Budget: €30-85/day.
Best visit: Oct-Apr (15-25°C, flamingos, possible ephemeral waterfalls).
1️⃣ UNIQUE GEOLOGY — Triassic Diapirism and Striking Mineralogy
1.1 Diapirism — Extremely Rare Tectonics
The “cirque” designation evokes alpine glacial formations. Aïn Ouarka: DIFFERENT tectonic violence = diapirism.
Geological Timeline 250 Ma → Present:
- 250-200 Ma (Triassic): Shallow seas, Maghreb lagoons. Intense evaporation → kilometer-thick salt deposits (halite NaCl), gypsum (CaSO₄·2H₂O), clays
- 180-150 Ma (Jurassic): Limestones, dolomites deposited over Triassic
- 100-65 Ma (Cretaceous): Cretaceous clays, limestones cover the pile
- 65 Ma-Present (Cenozoic → Atlas Orogeny): Compression crushes Maghrebides. Plastic Triassic materials (density 2.2 g/cm³: gypsum, halite) under pressure pierce rigid limestone envelope (density 2.7 g/cm³). Diapirs slowly rise (expansion dome). Erosion dissolves saline core → peripheral limestone walls form 1,672 m Djebel Chemarikh amphitheater.
Archimedes mechanism applied: Light rocks rise through dense rocks. Unlike volcanoes (matter expulsion), diapir = slow expansion dome over millions of years. At Aïn Ouarka process 65 Ma-present.
1.2 Inverted Lithostratigraphy — Unique Color Palette
Lithological column bottom → top:
| Level | Formation | Minerals | Color | Age | Thickness |
|---|---|---|---|---|---|
| 1 (Bottom) | Triassic clay-gypsum-saline | Halite (NaCl) rock salt, Gypsum (CaSO₄·2H₂O), Kaolinite/smectite clays | White gypsum, Red/ochre/purple clays (Fe oxides) | Triassic 250-200 Ma | Kilometers |
| 2 | Ophites (Tethys dolerites/basalts) | Pyroxene, olivine, plagioclase, alteration → Fe oxides | Dark green | Lower Jurassic (~180 Ma) | Decameters |
| 3 (Ramparts) | Lias-Dogger limestones-dolomites | Calcite (CaCO₃), dolomite (CaMg(CO₃)₂) | Gray-blue (without oxidation) | Jurassic 180-160 Ma | Hectometers |
Visual uniqueness: Blood-red clay mineral palette + brilliant white gypsum + dark green ophites + gray-blue limestones = Arizona/Death Valley type desert scene.
2️⃣ THERMAL WATERFALLS — Travertines and Ephemeral Falls
2.1 Permanent Travertine Waterfalls (Geochemical Process)
Mechanism:
- Deep thermal water 1500-2000 m emerges 44.5°C ± 2°C ultra-mineralized
- CO₂ degassing: pressure drop + turbulence + algal photosynthesis = CO₂ loss
- Reaction: HCO₃⁻ (bicarbonate) → CO₃²⁻ (carbonate) in alkaline medium (pH 7.3-7.8)
- Mineral precipitation: Ca²⁺ + CO₃²⁻ → CaCO₃ ↓ (white calcite)
- Over millennia: deposits = terraced pools, natural basins, “petrified waterfalls” ochre-white
Visual spectacle: Water seems “frozen in stone” — Pamukkale-like phenomenon but hotter + more mineralized.
2.2 Detailed Comparison Aïn Ouarka vs Pamukkale
| Criterion | Pamukkale (Turkey) | Aïn Ouarka (Algeria) | Advantage |
|---|---|---|---|
| Outlet temperature | 35-36°C | 44.5°C | Aïn Ouarka +8-9°C (hotter) |
| Travertine color | Pure white density <2.3 | Ochre-white density 2.4 | Pamukkale (purity), Aïn Ouarka (charm) |
| Mineralization | Pure bicarbonated 8.5 g/L | Sulfated-sodium 5.6-6.5 g/L | Pamukkale (more mineralized), Aïn Ouarka (sulfate-sodium properties) |
| Source flow | 140 L/s (powerful) | 3 L/s (modest) | Pamukkale (massive) |
| Chemical facies | Calcium bicarbonate | Sulfated-sodium | Aïn Ouarka (sulfates rheumatism) |
| Terraces hectares | 160 ha (colossal) | 2-3 ha (intimate) | Pamukkale (massive) |
| International status | UNESCO 1988 | Ramsar 2003 | Pamukkale (World Heritage) |
| Properties | Tourist (photography) | Proven therapeutic | Aïn Ouarka (health) |
| Water color | Milky white | Clear turquoise-emerald | Aïn Ouarka (aesthetic) |
| Annual visitors | 2 million tourists | <5,000 researchers + adventure | Pamukkale (mass) |
| Accessible | Paved road, 5* hotels | 4x4 track, rustic bungalows | Pamukkale (comfort), Aïn Ouarka (authenticity) |
Unique Aïn Ouarka synthesis = Hotter + Mineralized + Therapeutic + Wild + Endemism.
2.3 Ephemeral Falls — Spectacular 300-400 m Waterfall
Rare but DRAMATIC occurrence:
- Timing: Autumn storms (Sept-Oct) + spring (April-May)
- Trigger: 50-100 mm rain in a few hours
- Process: Runoff water concentrates on impermeable Djebel Chemarikh → 300-400 m cliffs → vertiginous falls violently feed lakes
- Rarity: 1-3 events/year
- Duration: 24-48 h after storm
- Popular legend: Waters “gush from the sky” — strong spiritual symbolism
