It’s the time of year where we all watch the rivers up here. Break-up in Fairbanks has lost the drama it had in the early days, before the flood control tamed the Chena River. There was a time when the Cushman Street bridge was rebuilt every year after the ice took it out.
Elsewhere across Alaska, the shifting ice still packs a punch. The ice jam in the above photo has caused flooding 90 miles upstream. Tanana, Alaska has experienced minor flooding from this. Communities all along the Yukon, from Eagle to Buckland have experienced severe flooding.
The Kobuk River has been added to the flood stage list. An ice jam could bring flooding from Kobuk to Ambler if the ice doesn’t break up soon.

In Fairbanks, we saw our first 80F degree day this season on Friday. It broke a record for not just the high temp of the day, but also broke a record for the highest low temperature for the day. It was the earliest 60F degree low on record for Fairbanks. It was certainly noticeable when I went out in the morning.
There is a lot of snow on the ground still. Anywhere from 12-18″ of depth, but the 50F degrees this past weekend has put the melt on. Lots of sun right now too:
Length of day: 16 hrs, 53 mins
Length of visible light: 19 hrs, 17 mins
Today will be 6 mins and 59 secs longer than yesterday.
The beavers have open water in front of their lodge, which happens for two reasons. Their swimming back and forth helps to keep the ice thinner, but there is also a methane release point in the same location, which helps to do the same thing. In fact, the circles of diminished ice in the background, are also methane pockets.
This is the Florida I really like. On my only off day in Orlando, not counting the day I flew in, I went out to Lake Kissimmee State Park in search of their 13 miles of trails. Luckily, not one of them had a TRAIL CLOSED sign at the trailhead.
Kissimmee is a 5900+ acre park with an incredible variety of terrain: From forest to floodplain and flatwoods to hammock, Kissimmee had it all.
One of several deer I saw while hiking. There were actually three here, with two hiding behind the ferns.
At the trailhead was a fishing hole that had a lot of attention. Mostly parents with kids were fishing from raised platforms. It wasn’t hard to see why they were fishing from above the shoreline: I immediately spotted two alligators floating offshore, with only the top of their heads out of the water. I could see fish everywhere, practically begging just below the water’s surface. I was told they were Florida Largemouth Bass, although they looked like a bunch of pet carp.
I didn’t hang out long enough to see one caught. I had just spent the past several days immersed in a sea of humanity, with a second round coming the next day, so I was looking for solitude on the trails. I found it too. The only company I had once I left the trailhead was several deer that I hiked past.
On the edge of a controlled burn
It was an absolutely beautiful day, with temps in the low 70’s F, not a cloud in the sky, and I had those 13 miles of trail to hike.
This remnant of Florida fascinates me. I honestly love hiking through the flatwoods and hammocks. It’s so different from what is in Alaska. It’s also kind of enjoyable to be hiking in a t-shirt in March and without mukluks.
They very recently had a controlled burn in the park, and one of the trails went right through one of the burns. The scent of burnt vegetation hung in the air. The burn was so recent, that I would occasionally walk through a pocket of air where I could smell the heat itself. I’m not sure if it was a hot pocket or just an area where the sun beat down in such a way as to amplify the scent, but it was intense.
A magnetic storm is headed our way from the sun, which should offer great aurora viewing Sunday and Monday. Hopefully the clear skies hang around tonight. With a forecast of -20F, I am assuming we will have the all clear for the aurora.
Ice core records from the Arctic show that Alaska’s Okmok Volcano had a massive eruption in 43 BCE. Following the eruption, there was an abrupt cooling globally, which led to crop failures, famine, disease, and eventually, social unrest. The Mediterranean region was no exception to this.
Such a shift in climate, coming a year after the assassination of Caesar, would have put great pressure on local powers. Strain was also felt in Egypt.
Okmok has a very active history. At one time, it had a 150 meter deep lake in its crater. A notch in the rim eventually drained the lake, although some small remnant lakes remain near cones B & D.
The eruptions of Okmok 8300 and 2050 years ago earn a Volcanic Explosivity Index rating of 6, which puts it on par with Novarupta and Krakatoa.
On 12 July 2008, Okmok erupted without warning, sending ash 50,000 feet into the air. It erupted continuously for almost six full days, causing transportation problems in the air and on the water for the region. That eruption was ranked a 4 VEI, which is considered “cataclysmic”.

Back to 43 BCE. The decade following the eruption was one of the coldest in a millennia, with 43 and 42 BCE being some of the coldest years. It is believed that a temperature drop of 7C from normal was a result of the volcanic eruption on the other side of the globe.
The Federal Government has designated the Chilkoot as a national historic trail. Gaining fame during the Klondike Goldrush, the Chilkoot was a major thoroughfare into the interior of the Yukon and Alaska. Prior to that, the trail was a major route for the Native population for a millennia.
The Chilkoot: Alaska to Canada
Currently, the Chilkoot is closed due to major trail damage from flooding this past autumn. A series of atmospheric rivers pummeled the area, The Taiya River reached flood stage on five different occasions during a two month period last fall, eroding banks and dislodging bridges along a large section of the trail, that follows the river.
There is hope that the trail will be open at some point this summer. The complete trail to Bennett Lake has not been open due to Canadian restrictions since the start of the Corvid pandemic. There is also hope that those restrictions will also be lifted for the upcoming hiking season.
As we slide into the Dark Abyss that is winter, there is one phenomenon that makes up for our shortened days: The Northern Lights.
With a geomagnetic storm in progress, and a forecast of clear skies, the first aurora of the season may be visible over the cabin in the next few days.
Aerial photo of Fairbanks after the Chena River overflowed its banks
This week is the 55th Anniversary of the Great Flood of 1967 that hit Fairbanks. The first half of August that year saw near continuous rainfall, that eventually was too much for the Chena and Tanana Rivers to hold back.
Downtown Fairbanks in August of 1967
At its peak, 95% of Fairbanks was under water. Over 6000 homes and businesses were a total loss, and as many sustained damage. Eight people lost their lives due to the flooding.
