Strokkur Geyser at Geysir Hot Springs in Iceland is the most active geyser in the park, erupting every few minutes. Occasionally it reaches heights of 120 feet, but on average the height of the spout ranges from 30-60 feet. It was bitterly cold on the day I visited, with high winds ragind down from the north, where a North Atlantic storm was raging. Without mittens, I could only stay out long enough to capture one shot of it erupting. For 15 minutes I watched the bluish water being sucked in and out of the mouth of the geyser as it bubbled and rumbled. I wasn’t prepared for the eruption, which came with a giant roar, throwing the boiling hot water into the air in a cascade that sent me running for safety. I counted myself lucky for having the presence of mind to snap this sole photo, then fled for the warmth of the visitor center.
