Yellowstone supervolcano 'turned the asphalt into soup' shutting down Natl. Park's roads

The extreme heat of a massive supervolcano under Yellowstone National Park is melting a major road in the popular summer tourist attraction. Park officials have closed the area to visitors.

Firehole Lake Drive, an offshoot of 3 miles over the park Grand Loop that connects the geyser Old Faithful and Madison Junction, is currently out of the limit. park operators say the danger of stepping on the seemingly solid ground in hot water is severely "high".

"Basically the asphalt turned into soup. It turned the gravel road in oatmeal" spokesman Yellowstone Dan Hottle.

the roads affected have access to the Great fountain geyser white dome geyser and firehole lake.

"There are a lot of other sites to see the thermal features in the park, "park public affairs chief of Al Nash said the weather channel. "I would not risk personal injury to see these during this temporary closure."

While the thermal activity under the park often leads to temperature fluctuations that may soften the asphalt along Yellowstone, Hottle said the latest wave seems worse than usual.

"But it's hard to know if a thermal area is warmer than normal, because we always fluctuating here," said as with the Los Angeles Times. "Road closures are as usual for us."

Maintenance workers must now lift the cast of the road asphalt, then apply lime and sand to absorb any remaining, according to Hottle

the spokesman said he hopes the road will reopen next week, adding that he does not believe the activity will significantly slow visits to the park.

Yellowstone supervolcano erupted around for almost 640,000 years as US Geological Survey records.

last December, geologists reported that the magma reservoir under the supervolcano is two and a half times higher than previous estimates.

"that does not mean you're doing anything bigger," said team scientist James Farrell analysis of the University of Utah. "It's just that our ability to see that it is getting better."

The supervolcano has the potential to shed more than 240 cubic miles (1,000 cubic kilometers) of magma through Montana, Idaho and Wyoming.

"we believe it will erupt again someday, but we have no idea when," Farrell said National Geographic.

in March, a viral video stampede of bison in the park led to rumors of an impending eruption.


in early April, scientists and park officials denied fears, saying the execution was a natural migratory bison occurrence, not a sign of impending volcanic activity. That same week, an earthquake of magnitude 4.8 shook section northwest of the park, marking the largest seismic activity in Yellowstone since 1980.

The earthquake occurred near "an area or plant uprising tied to the upward movement of molten rock in the super volcano, whose mouth or boiler, is 50 miles long and 30 miles wide, "Reuters reported in the time.

the uprising has no more likely volcanic activity, however, according to Peter Cervelli, associate director for science and technology in the volcano of the US Geological Survey science Center in California.

"the probability of that happen in our lives is very insignificant, "he said.
