Local Hazards
- Afternoon thunderstorms above treeline June-August - always descend below treeline by noon in summer

- Wildlife encounters - black bears (carry bear spray), mountain lions, and moose (more dangerous than bears) present throughout Colorado
- Flash floods in slot canyons and canyon trails during summer rainstorms - always check weather before canyon hikes
