Land's End and the Lost Land of Lyonesse

Image
Land's End, the dramatic, windswept tip of Cornwall, England, is a place where myth and geology intertwine. Legends whisper of Lyonesse, a kingdom swallowed by the sea, while the jagged cliffs reveal a story etched in ancient rock. A Land Forged by Fire and Ice: Imagine a time, 480 million years ago, when Cornwall lay submerged beneath a tropical sea. Volcanic eruptions spewed fiery ash, which over countless eons, compressed and metamorphosed into the dark slates and greenstones that dominate the cliffs today. Later, during the Ice Age, glaciers sculpted the landscape, leaving behind dramatic valleys and toweringtors. Witness these forces of nature at their most impressive at Longships Rock, a jagged island adorned with stripes of volcanic and sedimentary rock. Echoes of a Lost Kingdom: Legend paints a vivid picture of Lyonesse, a fertile land brimming with 140 churches and prosperous towns, tragically consumed by the ocean in a single night. While geological evidence doesn&

A Geological Journey through the Valley of Rocks

The Valley of Rocks, nestled in the heart of Exmoor National Park, England, is more than just a scenic wonder. It's a window into the Earth's ancient past, whispering tales of shifting continents, relentless seas, and the forces that shaped our planet. So, grab your metaphorical pickaxe and join me on a geological exploration of this captivating landscape. Rock Stars: The Lynton Formation Takes Center Stage The Valley's dramatic cliffs are composed of the Lynton Formation, some of the oldest Devonian rocks in North Devon. These fine-grained sandstones and slates, dating back a whopping 400 million years, hold a treasure trove of fossils. Brachiopods, trilobites, and even the remnants of early fish paint a vivid picture of a teeming marine environment that once existed here. The River's Mystery: A Geological Whodunnit One of the Valley's most intriguing features is its very existence. Why is it a dry valley, seemingly defying the logic of rivers flo
