Little Red River Cave is a closed and protected lava tube on the Mt. St. Helens Monument site. Permission was granted for the Cascade Grotto to enter and have a careful look around. For more information on caves and caving, or to find a caving club near you, check out the National Speleological Society at caves.org.
