A Quick Overview of the Seltún Geothermal Area in Iceland
The Seltún Geothermal Area feels like walking through a natural science experiment full of steam, bubbling mud, and striking colors. Located within the Krýsuvík geothermal field along the Mid-Atlantic Ridge, it’s a place shaped by powerful forces beneath the earth’s surface. Picture steaming fumaroles, hot springs with temperatures over 80-100-°C (176-212°F), and mud pots that gurgle and bubble like a witch’s cauldron.
What makes it even more impressive is the mineral-rich soil, painting the landscape in vivid shades of red, yellow, green, and orange. Surrounding the area, you’ll also find moss-covered lava fields and remnants of old volcanic craters, silent reminders of the region’s fiery geological history. A safe, sturdy boardwalk lets you explore this geothermal wonder up close without disturbing its fragile environment.
Post-glacial lava fields and evidence of volcanic eruptions, the most recent dating back to the 13th century, add to its rich history. Studied for its geothermal potential since the 19th century, Seltún is a vibrant mix of beauty, science, and natural power that’s impossible to miss.
The Bubbling Mud Pools and Fumaroles
The Seltún Geothermal Area hits your nose with a distinct smell the moment you step out of your car. It’s the sharp, sulfuric scent of hydrogen sulfide, often compared to rotten eggs and a clear sign that geothermal activity is hard at work beneath your feet.
The bubbling mud pools here are created when superheated water underground mixes with surface water, causing pockets of thick, boiling mud to form. Steam rises from nearby fumaroles, which vent hot gases straight from the earth’s core.
The combination of hissing steam, rising heat, and the constant bubbling creates a unique, almost otherworldly experience. It’s not just a feast for the senses but also an incredible example of geothermal processes in action.
The Vivid Colors of Seltún
The vivid colors at Seltún are created by geothermal activity, which makes it a photographer’s paradise. Mineral deposits like sulfur, iron oxide, and silica seep into the soil, painting the ground in shades of red, yellow, green, and orange. When sunlight hits just right, the colors appear even more striking, creating an incredible natural display.
What makes these colors so fascinating? The yellow hues come from sulfur deposits, while red and orange are the result of iron oxide reacting with the earth. Together with steaming vents and bubbling mud pools, the landscape has a kaleidoscopic effect that is unlike anything you’ll see elsewhere.
