Castle Rock is a cool natural landmark located in British Columbia, Canada. It's a special type of mountain known as a volcanic plug. You can find it about 13 kilometers (8 miles) west of Iskut and 8 kilometers (5 miles) northwest of Tuktsayda Mountain. Castle Rock is part of a huge area called the Pacific Ring of Fire, which has over 160 active volcanoes. It belongs to the Northern Cordilleran Volcanic Province and last erupted a very long time ago, during the Pleistocene epoch.
What is a Volcanic Plug?
A volcanic plug is like a giant, natural cork that forms inside an old volcano. Imagine a volcano that was once active. When it stopped erupting, the hot, melted rock (called magma) inside its vent cooled down and hardened. Over millions of years, the softer rock around this hardened core slowly wore away due to wind and rain. This left behind the tough, solid rock that filled the volcano's vent, creating a towering structure like Castle Rock!
Where is Castle Rock Located?
Castle Rock is found in the beautiful Stikine Country of northern British Columbia, Canada. It's part of the Klastline Plateau, which is a section of the larger Stikine Plateau. This area is also part of the famous Pacific Ring of Fire. This is a huge, horseshoe-shaped zone around the Pacific Ocean where many volcanoes and earthquakes happen.
Canada's Volcanoes
Even though Castle Rock last erupted a very, very long time ago (in the Pleistocene period), it's still interesting to geologists. It's one of Canada's top 10 volcanoes that have shown some recent seismic activity. Seismic activity means there are small earthquakes or ground movements, which can sometimes be a sign of volcanic activity deep underground.
Other Canadian volcanoes that have shown recent seismic activity include:
