Key points on "Underground Explorers"

Here are some key points on the story "Underground Explorer's" that I am reading for reading

• There is a straight trail from Bulmer Cavern to Blue Creek Cave.
• Neil Silverwood made the same trip and climed Mount Owen.
• There are 8km between the end of Bulmer Cavern.
• Bulmer Cavern already has 72km of passages.
• There are a maze of 4-metre-wide tube passages.
• Many of the walls in Bulmer Cavern are coated with Moonmilk.
