The Allure of Sea Stacks: A Geological Perspective
Sea stacks are dramatic geological formations, sculpted by the relentless power of coastal erosion. These solitary pillars of rock stand as testaments to time and the ocean's ceaseless efforts. Initially, they begin as part of headlands, sections of the coastline that extend out into the sea. Waves, driven by wind and tide, attack the base of these headlands, exploiting weaknesses in the rock such as cracks and fissures. Over time, this constant bombardment leads to the formation of caves. As the caves deepen and eventually meet, they create natural arches. The arch, however, is not a permanent structure. The roof of the arch eventually collapses under its own weight or due to continued coastal erosion, leaving behind isolated columns of rock – the majestic sea stacks we admire today.
The composition of the rock plays a crucial role in the formation and longevity of sea stacks. Harder, more resistant rock types, such as granite and sandstone, tend to form more durable stacks. Softer rock, such as shale, erodes more quickly, resulting in stacks that may be less imposing or have a shorter lifespan. The height and shape of a sea stack are also influenced by the local coastal scenery and wave action. Some stacks are tall and slender, while others are shorter and more rounded.
#1: The Old Man of Hoy, Scotland
The Old Man of Hoy is perhaps one of the most iconic sea stacks in the world. Located on the island of Hoy, part of the Orkney archipelago in Scotland, this towering sandstone stack stands at an impressive 449 feet (137 meters) tall. It's a popular destination for rock climbers and photographers alike, drawn by its dramatic presence and stunning coastal scenery. Its distinctive shape and sheer size make it a truly unforgettable sight. According to the Scottish National Heritage, the Old Man of Hoy is continually monitored for signs of instability, as coastal erosion continues to pose a threat.
The Old Man of Hoy's history is relatively short in geological terms. It's estimated to be only a few hundred years old, having separated from the mainland sometime between the 17th and 19th centuries. Despite its relatively young age, it's already a significant coastal landmark, attracting visitors from around the globe.

Immortalized in the James Bond film "The Man with the Golden Gun," Ko Tapu, also known as James Bond Island, is a distinctive limestone ocean stack rising dramatically from the emerald-green waters of Phang Nga Bay. While not the tallest of stacks, its unique shape – wider at the top than the bottom – makes it instantly recognizable. This unusual formation is due to the specific pattern of coastal erosion in the area.
Ko Tapu is part of the Ao Phang Nga National Park, and boat trips are readily available to explore the bay and its numerous limestone islands and caves. While visitors are not permitted to approach the stack too closely to prevent further coastal erosion, the views from the surrounding waters are spectacular. Statistics show that tourism to Phang Nga Bay increased by 40% after the release of "The Man with the Golden Gun," highlighting the stack's enduring appeal.
#4: HvÃtserkur, Iceland
HvÃtserkur, a 15-meter-high basalt stack island located off the shore of Vatnsnes peninsula in Northwest Iceland, is a dramatic coastal landmark steeped in folklore. Its name translates to "white shirt" in Icelandic, a reference to the guano deposits that cover its surface, giving it a distinctive white appearance. To protect its base from further coastal erosion, the stack has been reinforced with concrete. This intervention highlights the ongoing efforts to preserve these natural wonders for future generations.
According to legend, HvÃtserkur was once a troll who attempted to destroy the bells of a nearby monastery but was caught by the rising sun and turned to stone. The stack is a popular spot for photography, particularly during sunrise and sunset, when the light creates stunning reflections in the surrounding tidal pools. The unique shape of HvÃtserkur, with its two distinct arches, adds to its visual appeal and makes it a truly captivating geological wonder.

#5: The Needles, Isle of Wight, England
The Needles are a row of three distinctive chalk sea stacks rising out of the sea off the western extremity of the Isle of Wight, England. Once, a fourth needle stood alongside them, but it collapsed into the sea in 1764 after a storm. Despite the loss of the fourth needle, the remaining three continue to be a striking coastal feature. The name "The Needles" is somewhat misleading, as the stacks are not particularly needle-like in shape. It's believed the name refers to the now-vanished fourth needle, which was much more slender and pointed.
The Needles are a popular tourist attraction, accessible by boat or chairlift from Alum Bay. The colored sands of Alum Bay, visible in the cliffs surrounding The Needles, add to the area's visual appeal. The lighthouse at the end of The Needles provides an iconic image and a crucial navigational aid. The stacks are composed of hard chalk, which is relatively resistant to coastal erosion, but the relentless power of the sea continues to shape and modify them over time.
