Cinnamon Butte is a group of old cinder cone volcanoes and lava domes. You can find them in the Cascade Range in Oregon. These volcanoes are very ancient. All of them are older than about 6,845 years. We know this because they are covered in ash. This ash came from a massive eruption of Mount Mazama a long, long time ago.

Cinnamon Butte: Oregon's Ancient Volcanoes

Cinnamon Butte is not just one single mountain. It's a collection of several smaller volcanoes. These types of volcanoes are called cinder cones. They are usually cone-shaped hills. They are built from volcanic ash and rock pieces that erupt from a single vent.

Some parts of Cinnamon Butte are also lava domes. A lava dome forms when thick, sticky lava slowly oozes out of a volcano. It piles up around the vent instead of flowing far away. This creates a dome-shaped mound.

The Age of Cinnamon Butte

Scientists believe that all the volcanoes at Cinnamon Butte are very old. They are older than 6,845 years. How do we know this? Because they are covered in a layer of ash. This ash came from a huge volcanic eruption.

That eruption happened at Mount Mazama. Mount Mazama is now where Crater Lake is located. When Mount Mazama erupted, it sent ash far and wide. Since the Cinnamon Butte volcanoes are covered by this ash, it means they were already there when Mount Mazama exploded.

Other Important Vents in the Area

Cinnamon Butte is the main peak in this area. But there are other interesting volcanic vents nearby. These are also part of the same ancient volcanic activity. Here are some of them:
