| The National Park Service installed many stairs and pathways to help protect the lava tubes. This stairway is in the entrance to Hopkins Chocolate Cave. Note the "lava-cicles" on the rock surface above the stairs. These formed from molten rock splashing onto the roof of the tube at the time lava was flowing in the passage. Lava-cicles are common in most of the un-collapsed sections of the lava tubes throughout the park. |
