Vertical Character（Vertical Difficulty）
V1 (Very Easy):
• Rappels <10m
• Very easy climbing or down-climbing
V2 (Easy):
• Anchors easily accessible
• Rappels <30m
• Easy climbing or down-climbing
V3 (Moderate):
• Anchors easily accessible
• Max rappel height <45m
• Adequate spacing between drops for team reorganization
• Low-flow vertical water features
• Pools at the base of rappels are calm
• Systems are easy to rig
• Climbing difficulty up to 5.6, with potential rope protection at minor exposed sections
V4 (Difficult):
• Anchors not easily accessible
• Rappels may exceed 45m
• Rigging is technical but manageable
• Multiple-pitch rappels (ample stance platforms for anchors)
• Sharp edges require rope protection
• Low to moderate flow vertical waterlines that may affect balance or cause entrapment
• Pools at the base may be dynamic
• Climbing difficulty up to 5.8 (exposed sections require rope protection)
V5 (Advanced):
• Multiple-pitch rappels (hanging belays/anchors)
• Rappels may require crossing dynamic waterlines
• Moderate to high vertical flow (requires precise rappel line, balance, and line selection)
• Difficult rope retrieval or may require swimming with rope recovery
• Climbing difficulty up to 5.9
V6 (Expert)：
• Anchors are very difficult to reach
• Traverse lines are extremely difficult to rig
• High to very high vertical flow
• Rappelling through waterlines is very challenging (requires efficient execution, balance, and route-finding)
