Ok, Shield volcano in Borgarbyggð, Iceland
Ok is a shield volcano in Borgarbyggð featuring broad slopes built up from successive layers of lava. The mountain rises to 1,198 meters and displays the characteristic gentle profile formed by repeated eruptions stacked atop one another.
Ok formed during the Pleistocene epoch through multiple eruption phases that shaped its gentle profile. Over this long geological period, repeated lava flows accumulated layer upon layer to create the mountain as it appears today.
Scientists and geologists frequently study Ok volcano to understand the formation processes of shield volcanoes in the North Atlantic region.
Hikers can reach the volcano from the nearby town of Húsafell using marked hiking trails. The ascent requires moderate fitness as the routes involve extended walking times and varied terrain.
The mountain contains numerous lava tubes that formed during past eruptions creating natural underground passages. These tunnels extend throughout the structure and reveal the volcanic processes that built the landscape.
