A Journey Through Time: Exploring Oregon's Lava River Cave and Lava Cast Forest

Amidst the unending expanse of desolation, lay a barren lava field that stood as a testimony to the raw power of the Earth. Coarse, crumbled basalt stretched as far as the eye could behold, and cylindrical holes are all that remain of an ancient forest. Yet among the jagged lava rocks, flowers and trees found a way to stretch towards the sky.

Where is this incredible landscape?

None other than Central Oregon! Specifically the Sun River, La Pine, and Bend area.

Oregon's natural wonders never cease to amaze, and for those seeking to lean about the Earth's fiery history, a visit to the Lava River Cave and Lava Cast Forest is an absolute must. These two distinct geological marvels offer a unique glimpse into the state's volcanic past, inviting adventurers to delve into the depths of ancient lava flows and walk among the petrified remnants of a once-vibrant forest.

Lava River Cave:

As you step into the Lava River Cave, you're instantly transported to a subterranean realm that seems to defy time itself. Located just south of Bend, this is the longest lava tube cave in Oregon. The entrance reveals a portal to a world untouched by sunlight, where layers of volcanic rock have formed a labyrinthine tunnel that stretches nearly a mile beneath the surface.

Lava Cast Forest:

The Lava Cast Forest is nestled within the Newberry National Volcanic Monument. It reveals the haunting aftermath of a volcanic eruption that occurred more than 7,000 years ago!

Walking through the forest, you'll encounter ghostly molds of ancient trees, preserved for eternity in the solidified lava that once engulfed them. These eerie casts stand as silent witnesses to the cataclysmic event that reshaped the landscape. As you meander among the tree molds, a sense of timelessness envelops you, and you can almost hear the whispers of the long-lost forest that once flourished here.

As you walk the trail, try to spot the twisted trees and the different types of lava flows. Learn about why the trees grow this way, how lava tube caves formed, and so much more in our newest nature study!
