Hundreds of cars parked outside Yellowstone as park reopens after historic flood

Hundreds of cars 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.

Park managers raised the gates at three of Yellowstone's five entrances for the first time since June 13, when 10,000 visitors were ordered out after rivers across northern Wyoming and southern Montana surged over their banks following a torrent of rainfall that accelerated the spring snowmelt.

Some of the premier attractions at America's first national park will again be viewable, including Old Faithful — the legendary geyser that shoots towering bursts of steaming water almost like clockwork more than a dozen times a day.
