Cave Types

• Crevice Caves
• Talus Caves
• Sea Caves
• Lava Tubes
• Solution Caves

6
Crevice Caves

• found where a cliff face has pulled away from the
  stable rock face
• crack or crevice that sometimes widens enough for
  a person to explore

7
Talus Caves

• bolder caves are found at the base of a cliff
• usually the result of a rock slide type

8
Sea Caves

• generally found in sandstone formation areas

9
Lava Tubes

• are the result of molten lava flowing down a
  gully, valley or a depression

10
Lava Tube Features

• lava lakes

11
Lava Tube Features

• braided lava tube

12
Lava Tube Features

• lava curbs

13
Lava Tube Features

• stalagmite

14
Lava Tube Features

• stalactites

15
Lava Tube Features

• skylight

16
Solution Caves

• formed by water running off insoluble harder rock
  onto soluble rock
• minerals that have been dissolved by the running
  water eventually may be left behind by
  evaporation and pooling to give rise to
  spectacular features

Caving For Recreation

• cave environments can be very fragile
• code of conduct to maintain the caves
• caver's motto "Take nothing but pictures, kill
  nothing but time, leave no trace."

Karst Topography
27
Typical Karst Feature

• sinkhole

Conclusion

• Caving is a fascinating and growing recreational
  activity.
• Many interesting features may be produced during
  the formation of a cave.
• Vancouver Island is unique in Canada because of
  its extensive caving systems.
