Several thousand cars, trucks and recreational vehicles were backed up in long lines at entrances to Yellowstone National Park as it partially reopened Wednesday morning following record floods that reshaped the park's rivers and canyons, wiped out numerous roads and left some areas famous for their wildlife viewing inaccessible, possibly for months to come.
The devastating flooding that occurred along the Yellowstone River this week constitutes a 1 in 500-year event, according to the US Geological Survey.
Some roads have been flooded and others are covered in mud or rocks.
