The unique geology of the Lava Beds National Monument is the result of volcanic eruptions from the Medicine Lake shield volcanoes, which included cinder cones, lava beds, and over 700 lava tubes. The volcanic eruptions were a function of an oceanic plate subsiding under the continental plate.
One of the large draws of Lava Beds in the opportunity to explore dozens of developed caves. These caves are the remnants of streams of underground lava that pushed through the subsurface. After the lava exited, it left behind long tube-like caves. Lava Beds National Monument actually has the largest concentration of lava tubes in the United States.
With different levels of difficulty, ranging from least challenging to most challenging, all caves offer an opportunity to go subsurface. Guided tours are available in the summer, but with adequate preparation, most people can enjoy the caves without a guide.
Some good caves that have high ceilings and relatively smooth floors including Valentine Cave, Mushpot Cave, and Merrill Cave. Sentinel Cave is located right at the Visitor’s Center and is also an easy cave.
There are few things to keep in mind as far staying safe in the cave. Make sure you wear long sleeves and pants, closed toe shoes with sturdy soles. Other essentials for some of the more difficult caves include gloves, knee pads and a helmet. The surfaces can be uneven and jagged, so it is important to protect yourself. Also, each person should have a flashlight and extra light source or batteries.
