The Russian-American Company was established in 1799. The RAC received a renewable 20-year charter, which granted the company exclusive rights over trade in Russia’s North American territory.
The fur trade led the RAC to build a trading post on the Middle Kuskokwim River in 1841, which they named Kolmakovsky Redoubt. The blockhouse, above, was the first building erected. Eight more structures would also be constructed.
Kolmakovsky was the only Russian redoubt to be constructed in Alaska’s Interior. After the United States purchased Alaska from Russia in 1867, the redoubt eventually transferred to the Alaska Commercial Company.
The blockhouse stood alongside the Kuskokwim River for over 80 years. In 1929, the building was donated to the University of Alaska. The eight-sided log building was dismantled, the logs numbered, and then shipped to Fairbanks. It remained in storage for the next 50 years.
In 1982, the blockhouse, which has a diameter of 17′, was reconstructed behind the Museum of the North, on the UAF campus. In 2009, the University received a grant from the “Saving America’s Treasures” program to to do an all out restoration. A concrete pad was poured, any rotten logs were fabricated as the originals, and the roof was rebuilt. All but one of the interior horizontal roof supports are original.
The spruce logs are all connected by interlocking dovetail notches. There are no windows, only a low doorway, and three narrow musket slots. The Kolmakovsky blockhouse is the only Russian blockhouse ever found with a sod roof, the rest were all built with a plank roof.
Today, the blockhouse from Kolmakovsky Redoubt is still located near the Museum of the North on the University of Alaska – Fairbanks campus. The Kolmakovsky Redoubt site on the Kuskokwim has been placed on the Alaska Heritage list of historic properties and archaeological sites. A detailed excavation of the site was completed during the 1966 and 1967 summers by UCLA professor Wendall H. Oswalt. Well over 5000 artifacts were excavated, which are now a part of the collection at the Museum of the North.
This week is the 17 year anniversary of the 2002 Denali Earthquake. At a magnitude of 7.9, to date, it is the largest quake I have personally experienced.
On 23 October 2002, the Denali Fault released a magnitude 6.7 quake. That would be a foreshock of what was to come on November 3.
After the 6.7, I remember the Alaska Earthquake Center saying that the Denali Fault was capable of producing an 8.0. Sure enough, the fault came very close.
I was at an intersection in my ’66 Chevy C-20. All of a sudden, the truck was lurching all over the place, and I found it hard to stay on the brake pedal. There were two university students in the next lane, the passenger rolled down his window and asked what the hell was happening. I said, “Earthquake”. He then promptly hit the driver on the arm and said, “I told you it was an earthquake”.
The light changed, I drove on, but had to stop at the next light. The earth was still shaking. An elderly couple had been walking on the sidewalk, and the wife fell to the concrete, the husband was struggling to stay upright by hugging a signpost. Then the shaking was over. I rolled down the other window, to see if the couple was all right. They were, and I headed home to see if there was any damage.
The quake had ruptured 205 miles of earth along three different, yet connected faults in Interior Alaska. It was the largest ever recorded in Alaska’s Interior. It was the largest inland quake North America had seen in almost 150 years.
Both the Parks & Richardson Highways saw major damage. The Trans-Alaska Pipeline moved sideways 18 feet, and rose 5 feet. The engineers had designed for the fault, and the pipeline behaved exactly as it was designed to behave. Although, it did come within two feet of its sideways movement limit.
The Denali Earthquake was felt as far away as Louisiana.
Previously, the largest earthquake Fairbanks had experienced was a magnitude 7.3 in 1937.
It’s that time of year again. The aurora forecast from UAF’s Geophysical Institute is up and running again. A moderate aurora is being forecast for Thursday, with it being visible directly overhead for Fairbanks, weather permitting.
In Canada, Dawson City, Fort Nelson and Fort McMurray will find the northern lights directly overhead, assuming cloud cover doesn’t obscure viewing.
The aurora will be low on the horizon for Marquette, Michigan and Sundsvall, Sweden.
An equal, but opposite aurora will be taking place in the Southern Hemisphere, as well.
The Geophysical Institute at the University of Alaska – Fairbanks puts out their geomagnetic forecast daily.

It’s early August and people were starting to think “white stuff”. I had three jobs lined up, everyone desperate for me to start, yet not one of them was ready for me. What to do with the day off?
As luck would have it, Poker Flat Research Range had one of their summer walking tours that day, so I drove the 25 miles out to Chatanika.
PFRR is the world’s largest land-based rocket range. The facility is owned by the University of Alaska – Fairbanks. They launch sounding rockets from the range, in order to study the Earth’s atmosphere and the interaction between the atmosphere and the space environment.
Study ranges from the Earth’s magnetic field to the aurora. NASA is prominent at the range, but researchers come from all over the world. All of the rockets launched from PFRR return to the Earth’s surface, and the range collects the spent payloads every summer. There is a reward paid out to anyone finding material from Poker Flat.
The building above is open on the far end. The interior of the building, and the actual launch pad, was off limits to photography. It’s a NASA rule that doesn’t thrill UAF apparently, but we all honored the rule. The sounding rocket is brought in on what is basically an open trailer. The rocket is loaded onto the launcher, which looks like a giant erector set with a large pivot. The building itself is sitting on a pair of tracks. When ready to begin countdown, the building is pulled back away from the pad, and the rocket is spun vertical with the large erector set pivot.
The control center was surprisingly manual in operation. Scientists are extremely fussy about launch conditions, and they often pull the plug with one second to go. An automatic system does not give the flexibility that is needed, so there is still a “launch button”.
That doesn’t mean there is a shortage of cable, wires, or connectors.
PFRR does a good job with the tour. It’s pretty relaxed, and a nice way to spend some time outdoors, for the most part, in an Interior Alaska summer. After the tour, don’t forget to stop by the Chatanika Lodge, which is just down the highway.
With the extension of these unusually warm temps here in Interior Alaska, let’s go back to this past March, when snow was on the ground, and the UAF students were climbing the ice wall on campus.
Researchers from around the globe have congregated on Alaska’s Arctic coast. They are planning a once in a generation expedition into the heart of one of the harshest environments on Earth: The Arctic.
It’s a 12 month, 17 nation, 300 scientist effort aboard the German ice breaker Polarstern, to document climate change in the Arctic. This coming autumn, the Polarstern will be positioned in a remote part of the Siberian Arctic, and then wait to be frozen in the ice. The research vessel will then flow with the floe; traveling with the ice as it moves across the Arctic Ocean.
Only twice has a transpolar drift happened successfully in history. Norwegian explorer Fridtjof Nansen did it first in 1893. Ten years ago, a small sailing ship named the Tara also completed a transpolar drift without the sea ice crushing its hull.
NASA’s Goddard Space Flight Center, the National Science Foundation and universities from Alaska-Fairbanks to Oregon State to Dartmouth are involved. Most northern nations are playing a role, as well. Russia, China and Sweden have all committed ships and aircraft for resupply support. Japan and Switzerland have developed new research equipment especially for the expedition.
Unlike Antarctica, there is no land at the north pole to build a permanent research station. The RV Polarstern is the next best thing. At any one time, 60 people will be living and working on the ice breaker. Resupply will take place every 60 days, weather permitting. Researchers will also be swapped out during resupply runs.
Time is running short for a expedition like this one. The key is to find old sea ice, 4-5 years old, and get locked into that. Since 1980, 95% of Arctic sea ice that is 4+ years old, has been lost. In the graph above, the lightest yellow is 1 year old ice, the dark purple 5+ years old.
It should be an interesting study, although researchers on board the ice breaker from December to February will not see the sun. They should see polar bears, however.
