Flying back from Alaska on yet another recent trip, I was able to spot Rose Spit, which featured as a Where in the West challenge back in October of 2010. The shape of the northeastern tip of Graham Island — an island in the Haida Gwaii, or Queen Charlotte Islands, off of the coast of British Columbia up near Prince Rupert — always fascinates me.
The northern portion of Graham Island, with
I am always interested in non-traditional data sets that can shed some light on climate changes. Ones that I’ve discussed previously are the frequency of closing of the Thames Barrier and the number of vineyards in England. With the exceptional warmth in Alaska last month (which of course was coupled with colder temperatures elsewhere), I
These charts show how proved oil reserves have been increasing in some parts of the United States – especially in North
“You might think it’d be hard not to notice 68 million tons of rock and debris suddenly crashing down a mountainside. But when one of the biggest landslides of the past four years occurred in a remote region of Alaska, researchers knew almost everything about it except its exact location.” Quoted from Adam Mann’s blog
The Landslide Blog has aerial photos and commentary on a rock avalanche that ran out about three miles over a glacier along the flank of Mount La Perouse in southeastern
Three out of the four times that I have flown between Anchorage and Nome, Alaska, the weather was overcast and clouds covered much of the landscape below. However, when I flew from Nome to Anchorage in August 2013 I was fortunate enough to fly on a day when skies were clear. I was thrilled to obtain a spectacular view of Denali, also known as Mt. McKinley, the highest peak in
The last deadly earthquake in Alaska occurred in 1964. It killed 131 people in Alaska and 16 more by tsunamis in Oregon and California. In the last 50 years there have been no earthquake deaths in Alaska even though several large earthquakes have occurred. Has that been
Using seismic data, Colin Stark and colleagues have detected a new, very large landslide in Alaska on Sunday. At about 68 million tonnes, this may have been the largest natural landslide since
A US Senator from Alaska says… “Opening up world markets to U.S. crude oil will lower the global price, which will in turn lower the global prices for petroleum products.” A US airlines industry VP says… “Exporting U.S. crude makes little sense. [...] If we allow for the export of U.S. crude, we’ll have to
WSDOT released an update on February 7 with some conclusions regarding the blockage that has stopped the Alaska Way Viaduct Tunnel Boring Machine, Bertha's progress since December 6. Now they don't think it was necessarily the well casing after all.
They cite two factors that contributed to the blockage. First, the cutterhead was clogged with material. You can see an cool short video of a worker unclogging the cutterhead. Not terribly dramatic, but still cool. The second factor was [...]
The Keystone Canyon avalanche, a very large snow and ice avalanche on the Richardson Highway in Alaska has blocked the road and impounded a
Back in September 2013 I visited Dubai for one day during a layover when I was flying from Alaska back to South Africa. I was fortunate enough to be able to sleep on the flight from New York to Dubai, so when I arrived in Dubai I took a quick shower at the hotel then headed out to explore for a few hours. I spent some time at the Dubai
upr.org One of the biggest earthquakes in U.S. history didn’t occur in California. Or Alaska. It happened in the country’s midsection some 200 years ago in an area where today seven states straddle the Mississippi River Valley. READ
USGS has released a new video that looks back at the Magnitude 9.2 event now known as “The 1964 Great Alaska Earthquake and Tsunami”. This event changed scientific understanding of earthquakes because it was the first major earthquake that was studied from a plate tectonics

2013 was a particularly eventful year for the world's volcanoes. Out of an estimated 1,500 active volcanoes, 50 or so erupt every year, spewing steam, ash, toxic gases, and lava. In 2013, erupting volcanoes included Italy's Mount Etna, Alaska's Mount Pavlof, Indonesia's Mount Sinabung, Argentina's Volcán Copahue, and a new island emerging off the coast of Nishinoshima, Japan. In Hawaii, the famed Kilauea volcano continued to send lava flowing toward the sea.Collected here are scenes from the [...]
I apparently haven't participated in the Year of Travel Meme since 2010, possibly because I traveled back and forth across the same old roads in 2011, 2012, and 2013 -- or possibly I was just too busy at the holiday time of year to get that kind of blog post together. This year, Evelyn Mervine got her Year of Travel 2013 post up right at the end of the year; I'm getting mine up before the end
Not sure I've ever seen this orange de-icing goop before, although maybe
I've only previously noticed de-icing operations at nighttime.
Orange de-icing fluid being sprayed over the snow-covered wing.
De-icing fluid dripping down the window from the top of the aircraft.
It turns out that the orange color indicates that a Type I de-icing fluid is being
I'm sitting here inside flight 112--I think--with my phone in airplane mode, wondering if I can create a blog draft that I can save and post later. Obviously, the rest of this test will have to be completed after switching out of airplane mode and connecting with a wireless or other network.
And now for an obligatory photo upload to accompany this
The USA.gov blog has a number of photos of aurorae over Alaska from the Bureau of Land
National Geographic has a video that shows a laboratory simulation of volcanic lightning in a lab. See volcanic lightning in Alaska
