An injured hiker was reported stranded in The Subway in Zion National Park on Saturday night as rains posed a risk of flash flooding in the slot canyon.
Another hiker called 911 after exiting The Subway canyon hike on Saturday evening to report the hiker had suffered a lower leg injury, said Ranger Tim Hearns. Rescuers did not yet know the nature or severity of the injury, or whether the hiker was mobile, Hearns said. It also wasn't clear which part of The Subway the hiker was in. Some parts of the hike allow access to higher ground; other parts pass through deep slot canyons that can expose hikers to flash flooding.
