Mount Edziza volcanic complex

A large group of volcanoes sits in Canada.

These mountains were made by old lava. Most of the lava came from long ago.

Now, you can find warm water springs there. The tall peaks have ice on them.

Many animals live in the valleys. Bears, sheep, and birds live there. Some trees grow near the streams. It is a very big and special place.

Mount Edziza is a large group of volcanoes in Canada.

This area is on the Tahltan Highland. It has many different kinds of volcanoes. Some are tall stratovolcanoes. Others are wide shield volcanoes. There are also small cinder cones and lava domes. These volcanoes formed over 7.5 million years.

The highest peak is Mount Edziza. It is covered by a cap of ice. Many glaciers flow down from the top. The area has warm springs on the west side. These springs are the only active parts now.

Many animals live in the valleys. You can find bears, moose, and caribou there. Trees like white spruce grow near the streams. The Tahltan people have lived nearby for a long time. They once used volcanic glass called obsidian to make tools.

You can only reach the park by plane or horse trails. It is a very big and wild place.

The Mount Edziza volcanic complex is a huge group of volcanoes in Canada.

It sits on the Tahltan Highland in northwestern British Columbia. This area is a wide, steep-sided plateau made of lava. It is a very important part of the local landscape. The complex is much larger than many people realize. It covers a very wide area of land.

This complex works through many different volcanic shapes. It has tall stratovolcanoes and wide shield volcanoes. There are also smaller cinder cones and lava domes. These different shapes formed over 7.5 million years.

This happened during five different cycles of magmatic activity. These cycles lasted through four different geologic epochs. Eruptions created thirteen different types of volcanic rock formations.

People have studied this amazing place for a long time. Geological work began in the area at least by the 1950s. The most detailed studies happened during the 1960s.

Indigenous peoples have lived near the complex for thousands of years. The Tahltan people used volcanic glass to make tools. This glass is called obsidian. They could find high-quality obsidian on Obsidian Ridge.

There are many specific facts about the mountains here. Mount Edziza is the highest peak at 2,842 meters.

Ice Peak is another large volcano that is 2,710 meters high. The Spectrum Range reaches an elevation of 2,510 meters. The complex is located southeast of Telegraph Creek. It is also southwest of Dease Lake. Many streams like Mess Creek and Kakiddi Creek flow around it.

Nature connects this volcanic land to the world we know. The area has warm summers and cold, snowy winters.

Animals like bears, moose, and caribou live in the valleys. You can see trees like white spruce and lodgepole pine. Some parts of the mountain are always covered in ice. This ice forms glaciers that stretch down to lower ground. Even today, hot springs stay warm on the western side.

The Mount Edziza volcanic complex, often abbreviated as the MEVC, is a massive group of volcanoes and lava flows. It is located in northwestern British Columbia, Canada, on the Tahltan Highland. This complex forms a broad, steep-sided plateau that covers a vast area. It is a significant geological feature because it represents a long history of volcanic activity. The highest summit reaches an elevation of 2,842 meters. This makes the MEVC the highest of four large volcanic complexes in this north-south trending region.

This volcanic system works through several different types of eruptions and structures. It includes stratovolcanoes, which are tall, cone-shaped mountains. It also contains shield volcanoes, which are broad and have gentle slopes. Other features include cinder cones and lava domes. These different forms were created during five distinct cycles of magmatic activity. This magma, or molten rock, moved through the earth over the last 7.5 million years. These cycles spanned four different geologic epochs. The eruptions produced 13 different geological formations made of various volcanic rocks.

Four central volcanoes dominate the landscape of the complex. Mount Edziza is the highest and is a large, ice-covered stratovolcano. Ice Peak is another major feature, standing at 2,710 meters. It is a composite stratovolcano that has been worn down into a steep, pyramidal peak. The Spectrum Range is a third major part, reaching 2,510 meters. It is a nearly circular dome that is more than 10 kilometers wide. Finally, Armadillo Peak represents the eroded remains of a small caldera. A caldera is a large crater formed when a volcano collapses.

Small cinder cones are scattered across the plateau in specific groups. The Desolation Lava Field on the northern slope of Mount Edziza contains several cones. These include the Eve, Storm, Moraine, Williams, Sleet, Twin, Sidas, and Triplex cones. On the southwestern flank of Ice Peak, the Snowshoe Lava Field holds five named cones. These are the Tennena Cone, Coffee Crater, Keda Cone, Cocoa Crater, and The Saucer. The Mess Lake Lava Field contains only one named cinder cone, called the Ash Pit. Other isolated cones, such as Nahta Cone and Kana Cone, sit at the edges of the complex.

Human history is closely tied to this volcanic land. Indigenous Tahltan people have lived adjacent to the MEVC for thousands of years. They used volcanic glass found here to create tools and weapons. This glass is known as obsidian. High-quality obsidian can be found specifically on Obsidian Ridge. Scientific interest in the area grew in the mid-20th century. Geological work has been carried out intermittently since at least the 1950s. The most detailed scientific studies were conducted during the 1960s.

Nature and climate shape the way the MEVC looks today. The area experiences warm summers and cold, snowy winters. Snow and ice remain on the highest volcanoes throughout the entire year. This ice forms an ice cap with several outlet glaciers. These glaciers stretch from the summits down to lower altitudes.

The complex is surrounded by many streams that drain the volcanic flanks. These include the Little Iskut River, Kakiddi Creek, the Klastline River, and Mess Creek. These waterways belong to the larger Stikine River watershed.

The MEVC is a vital part of the Boreal Mountains and Plateaus Ecoregion. This ecological region includes high plateaus and rugged mountains. In the valley bottoms, you can find forests of black and white spruce. Mid-slopes are often covered in birch, spruce, and willow trees. Animals like bears, moose, caribou, and sheep live in these habitats. While the area is mostly wild, it is also a large provincial park. Much of it can only be reached by aircraft or horse trails.
