Volcanoes aren't a rare thing, however, what makes this one stand out is that it was discovered a few weeks ago......
about 150 ft. or so under the water.
The volcano itself last erupted over 10,000 years ago but at that time, it wasn't under the ocean.
That's what makes it so interesting for geologists, and also the fact that nobody currently living knew it was even there until just a few weeks
U.S. Forest Service Geologist Jim Baichtal, who is based on Prince of Wales Island, and Anchorage USGS geologist Sue Karl were looking at some
hydrographic surveys, something geologists tend to do. When we were done, I noticed the area from Thorne Arm to Rudyerd had been surveyed,” Baichtal
said. “I zoomed in and there was this large… some kind of volcano, and two other dome-like structures.” Karl added that, “This new NOAA survey
allowed us to see things that people had never seen before.”
Baichtal said that after spotting the cone-shaped mass, he used a special computer program to look more closely at the surveys, and they could see the
vent still was intact. They also could tell that it erupted in the air, even though it’s now under water.
They were able to go down and survey it and brought back 2 rock samples which will give them more information which they are still analyzing.
At the moment, they figure that the volcano erupted within the last 13,000 years, after the ice retreated, as the land was slowly bouncing back, and
when sea levels were lower.
The newly discovered volcano is very close to New Eddystone Rock, which is what’s left over from another volcano, which may have erupted around the
same time frame. They are both near the entrance to Misty Fiords National Monument.
I find this stuff very fascinating and thought I would share it....
