that is moderately active. This crack is likely related to that, not to any "Yellowstone hot spot".
BULLETIN - JULY 23 -- MAJOR SEISMIC ACTIVITY AT YELLOWSTONE VOLCANO -- SEE BOTTOM FOR UPDATE
Grand Teton National Park has closed the Hidden Falls and Inspiration Point tourist attractions because of concerns that a fissuring rock wall could pose a danger.
Grand Teton is near the Yellowstone Super volcano; the second largest volcano on earth. Concerns are now being raised that the Yellowstone volcanic system may be preparing to emit lava in similar ways that Kilauea volcano has been doing in Hawaii for two months; except Yellowstone is 2,000 times bigger.
National Park Service spokeswoman Denise Germann says growing cracks and fissures were observed in the large buttress above Hidden Falls.
“Yesterday, Exum guides noticed cracks in the rocks,” Teton park spokeswoman Denise Germann said. “They communicated that to rangers this morning, and when they went to investigate they realized it had actually gotten bigger and expanded.”
Germann tells the Jackson Hole News & Guide that the crack is about 100 feet (30 meter) long and runs horizontally along a rock wall that’s at least 100 feet tall.
“The whole area is prone to geological activity,” Germann said, “but this was a very notable difference.”
"The notable changes in the rock over the past 24 hours spurred park rangers to implement a temporary closure and initiate a risk assessment with subject-matter experts."
It is hard to conceptualize the shear size of the Yellowstone volcano system. The Caldera - the mouth of the volcano - is 213 MILES around! The underground magma system which feeds that gigantic "mouth" runs countless miles farther in many directions.
In Yellowstone National Park, which is north / northeast of Grand Teton National Park, contains some of the most fascinating geological wonders of the world. For instance: Geysers that hurl steam and water hundreds of feet into the air on a regular basis.
One of those Geysers is called "Old Faithful" and it erupts with steams and water several times a day. A much larger nearby Geyser, the largest known Geyser in the world, is called "Steamboat Geyser." In the past two months, activity at the steamboat geyser has increased very noticeably. There have been eleven steam and water eruptions from Steamboat in the last two months. Prior to that, there were only eleven eruptions in the past 28 YEARS.
So clearly, something is now taking place with the Yellowstone volcanic system. What that is, and what it may lead to, are yet unknown, officially.
Unofficially, a reasonable person can come to a very obvious conclusion about what all this activity is leading to. And if that conclusion is correct, life in the entire United States could be suddenly and dramatically altered very badly.
Park officials are searching for a Park Service expert to assess the risk of the potentially unstable rock wall.
For now, Exum Mountain Guides have relocated their practice school to another location. Hidden Falls and Inspiration Point — among the park’s busiest attractions — are totally off-limits until further notice. Access to Cascade Canyon is still possible via the horse trail along Jenny Lake.
Jenny Lake Boating is continuing its services ferrying tourists across Jenny Lake, which remains open generally.
“It’s a very busy season for us,” Germann said, “but out of an abundance of caution we believe the best thing to do is have an emergency closure.”
