Introduction
Fjords are narrow, deep inlets carved by glaciers during ice ages and later flooded by the sea. They feature steep walls, deep water, and dramatic scenery.
The largest fjords are found in Greenland, Norway, Canada, and Chile, all regions that were heavily glaciated during the last ice age.
1. Scoresby Sund, Greenland
- Length: 350 km (217 mi)
- Depth: Up to 1,450 m
- Width: Varies, up to 30 km
Scoresby Sund is the largest fjord system in the world. It branches into several sub-fjords that penetrate deep into Greenland's ice-covered interior.
The fjord is home to large populations of muskox, Arctic fox, and polar bears. Massive icebergs from Greenland's glaciers float through its waters.
2. Sognefjorden, Norway
- Length: 205 km (127 mi)
- Depth: 1,308 m
- Deepest Point: Deeper than surrounding ocean
Sognefjorden is the longest and deepest fjord in Norway. Its depth exceeds that of the North Sea, which is only about 95 m deep at its shallowest.
The fjord is surrounded by snow-capped mountains, waterfalls, and picturesque villages. It is a UNESCO-adjacent area and a major tourist destination.
3. Hardangerfjorden, Norway
- Length: 179 km (111 mi)
- Depth: 800 m
- Famous For: Fruit orchards along shores
Hardangerfjorden is known for its fruit orchards that bloom spectacularly in spring. The microclimate created by the fjord's water allows fruit to grow at this northern latitude.
4. Beagle Channel, Chile/Argentina
- Length: 240 km (150 mi)
- Named After: HMS Beagle (Darwin's ship)
- Location: Tierra del Fuego
The Beagle Channel is a strait at the southern tip of South America. It was charted during Darwin's famous voyage and is surrounded by glaciers and sub-Antarctic forests.
5. Milford Sound, New Zealand
- Length: 15 km
- Depth: 291 m
- Rainfall: ~6,800 mm/year
- Nickname: Eighth Wonder of the World
Milford Sound is the most famous fjord in the Southern Hemisphere. Rudyard Kipling called it the "eighth wonder of the world."
It receives about 6.8 meters of rain per year, creating temporary waterfalls that cascade from the cliff walls during storms.
6. Geirangerfjorden, Norway
- Length: 15 km
- Depth: 600 m+
- UNESCO: World Heritage Site
Geirangerfjorden is a UNESCO World Heritage Site and one of the most visited fjords in the world. Cruise ships look tiny against its massive cliff walls.
7. Kenai Fjords, Alaska, USA
- Glaciers: 40+ glaciers
- Ice Field: Harding Icefield (1,813 km²)
- Wildlife: Orcas, seals, puffins
Kenai Fjords National Park contains over 40 glaciers flowing from the Harding Icefield. Tidewater glaciers calve icebergs directly into the fjord waters.
8. Ilulissat Icefjord, Greenland
- Width: 7 km
- Ice Production: 46 km³/year
- UNESCO: World Heritage Site
Ilulissat Icefjord is the most productive glacier outlet in the Northern Hemisphere. The Sermeq Kujalleq glacier calves 46 cubic kilometers of ice per year into the fjord.
Key Facts
- Scoresby Sund is 350 km long, the largest fjord system on Earth.
- Sognefjorden at 1,308 m is deeper than the surrounding North Sea.
- Fjords are found in all regions that were heavily glaciated during ice ages.
- Milford Sound receives 6.8 meters of rain per year.
- Ilulissat Icefjord produces 46 km³ of ice per year.
Fun Facts
- Sognefjorden is so deep that submarines can hide in it undetected.
- Milford Sound was called the "eighth wonder of the world" by Rudyard Kipling.
- The Beagle Channel is named after Darwin's ship, not the dog breed.
- Ilulissat Icefjord may have produced the iceberg that sank the Titanic.
Final Thoughts
Fjords are among the most dramatic landforms on Earth, carved by ancient glaciers and flooded by rising seas. From Greenland's massive Scoresby Sund to New Zealand's iconic Milford Sound, these glacial valleys showcase nature's sculptural power.
