Blame earth, rain and fire for disruptions at Yellowstone National Park on Tuesday.
Electricity was knocked out across the park for about an hour Tuesday because of a wildfire to the north.
A few hours later, a thunderstorm caused landslides that closed the road between Gardiner and Mammoth Hot Springs.
A downed power line started the fire in Yankee Jim Canyon on Monday about 10 miles from Yellowstone in the Gallatin National Forest. The fire grew to about 1 acre and appeared to be under control early Tuesday. But the fire flared up again, knocking out one power line just before 11 a.m. and another parallel line around 12:05 p.m., according to Claudia Rapkoch, a spokeswoman for NorthWestern Energy.
The second line that went down serves Gardiner and all of Yellowstone.
Emergency generators kicked in as soon as the power went off to keep emergency communications and other crucial functions operating, said Al Nash, a Yellowstone spokesman.
Offices, hotels, restaurants and other buildings in the park went dark for about an hour until other generators were fired up.
Commercial power was restored to Yellowstone just after 1 p.m., Rapkoch said.
Then at around 2:30 p.m., a thunderstorm producing heavy rain and hail moved through the park, causing flooding and landslides in the Gardiner River Canyon.
The road was closed between the North Entrance station and the Montana/Wyoming state line and was reopened Tuesday evening. No one was hurt, and the park's other entrances remained open.
