Suggestions of Spring

The sun is not yet above the horizon at 07:51 AKDT on the Vernal Equinox – which arrived in this area at 02:29 this morning – but it is light enough to see the surrounding space which remains cloaked in a 22.0 inch (55.9 cm) snow pack although the incessant winds across March have cleared virtually all the snow from the trees.  Our maximum snow pack was 35.5 inches (90.2 cm) back in middle February but within a week or so of that time all precipitation ceased.  This dry spell, coupled with almost Chinook style winds and the longer, sunny days definitely did a number on the slowly compacting snow pack.  Yesterday we flirted with 35° F (1.7° C) under sunny skies but at least the winds of March seemed to have weakened to just gentle (8-12 mph or 13-19 kph) breezes.  This morning the air is calm for the first time in over two weeks.

As I stare out my second floor office window I can just recognize some suggestions that spring is not far away even here at sixty two degrees north latitude.  The exhaust from my Toyo stove, which drifts almost directly across my office window when the air is calm, is much less dense and is occurring less frequently than a few weeks earlier.  While we are seeing a -2.2° F (-19° C) air temp I’m also expecting to see an afternoon high around 35° F (1.7° C) under sunny skies.  The boughs of the spruce trees are beginning to ‘perk up’ a bit after bearing heavy amounts of snow from late December through middle February.  And our direct daylight is now up to 12 hours 17 minutes and increasing daily by 6 minutes 1 second!  These longer days are beginning to slowly melt the snow pack even if the air temps remain well below freezing.  Indeed, when working towards my goal of 10,000 steps/day – I’m currently around 7,800 steps/day – I have started taking a collapsible walking staff with me as the icy hard packed snow coverage on the back roads is becoming slippery especially when just a thin layer of water appears atop it.  This lack of traction is emphasized as I watch my male German Shepherd Dog (Qanuk) perform multiple slips and slides along with a few face plants as he revels in our daily walks.  Anana, my female Alaskan Malamute, is more restrained and hence remains upright most of the time.  There is something to be said for the wisdom of age!

I finally was able to experience a ‘real’ south central Alaskan winter after three previous ‘winters that weren’t’.  I did feel the bite of -40° F (-40° C) air temps, wind chills another ten to fifteen degrees below those temps and an almost three foot snow pack that remained for at least two and a half weeks.  I was treated to intense and vibrant auroral displays across much of the late fall when clear skies coincided with the Aurora Borealis.  Having completed my fourth consecutive winter in Alaska I think I can finally claim to be a veteran of ‘The Great Land’ and its kaleidoscope of weather conditions.  But maybe most surprising to me is I’m actually ready for the seasonal change.  During the three previous Vernal Equinoxes I was lamenting the end of winter and not enthusiastic about the oncoming spring with its insects and tourists.  But now I find myself awaiting the warmer weather even if it brings mosquitoes and the inevitable tourist traffic and congestion.  Perhaps I’m finally becoming sanguine with the aforementioned as well as the knowledge that within five to six weeks there will be no dark night skies again until early September?

Before long I’ll be indulging in what has become a ritual involving preparing for spring and summer.  I’ll be swapping tools and equipment between the mud room/front porch and the shed.  The generator will be drained of fuel which will go into the Escape’s gas tank.  The battery conditioner/recharger will be stowed in the shed and I will be getting the ‘Mosquito Magnet’ ready for operation.  I’ll be smearing some ‘bat attractant’ on the entrance to the bat house which my buddy Sarge hung last October; hopefully I’ll attract some Little Brown bats and convince them to set up house and help control the mosquito hordes.  In this same vein I’ll be relocating my tree swallow houses for the third time in the hopes I can attract some nesting pairs to add to my attempts at natural mosquito control.  So many of these actions are now ‘old friends’ and form a kind of seasonal dance or celebration.  For the first time since I relocated I’ll be doing them with joy and the knowledge that regardless of what the upcoming six months may hold for me winter will again return and I will have the opportunity to experience yet another spring, summer and fall in ‘The Great Land’.

Low Angles in High Latitudes

As we rapidly approach the calendar start of winter – the Winter Solstice occurring on December 21st this year at 14:03 AKST while the meteorological start to the season was December 1st – I once again find myself contemplating the boreal forest and the sky above its mix of birch and spruce trees.  I spend far too much time parked in front of a monitor but I do have a large window just three feet to my left which looks out from the second floor office into the immediate surroundings.  We still remain far short of snow with just 7.5 inches of snow pack and the temperatures have been see-sawing back and forth around the freezing point which is exceptionally warm.  All told this looks to be my second consecutive ‘winter that wasn’t’; while not happy with the prospect I am working to become more sanguine with this concept…maybe next year?

Yet there’s still a lot to marvel at in my new Alaskan home and one of those observations is the extremely low angle to the sunlight this time of year.  While out walking ‘the kidz’ yesterday early afternoon I was reflecting upon just how much the partly cloudy sky resembled an early sunrise or sunset; the underside of many of the Altocumulus stratiformis clouds of the mid-altitude cloud deck were orange and red while the few Cirrus intortus at a higher elevation were brilliant white tinged with fiery yellow against the azure sky.  I had to remind myself this was just 13:25 AKST and thus only a bit more than half way through our current 5 hour, 3 minute and 47 second direct sunlight period; according to my tables the solar ‘noon’ occurred at 12:56 AKST.  Although there were still many clouds on the western horizon when I could see it – the boreal forest really surrounds this area – the sun was indeed very low. Just how low is ‘low’?  Using NOAA’s Solar Position Calculator ( I calculated just 5.4 degrees above the horizon at 12:59 AKST.

This is extremely low; for comparison using Detroit (MI) on this same date and the same time (12:59 EST) I came up with an angle of 23.94 degrees.  No wonder this former Midwest boy thinks the sun is darn low up here!  Of course I was aware of this phenomenon as its fairly straightforward physics represented using geometry but to actually be standing on a shadowed, snow-covered back road surrounded by the immense and silent boreal forest while marveling the sun can hardly be seen even between the breaks in the trees really brings the concept home.  I know from previous experience that on the summer solstice a few hours later the sun will reach almost 52 degrees above the horizon; what a difference!

I’d heard many folks – mainly photographers – talk about ‘flat light’ and they often bemoaned its influence at the higher latitudes.  Only after I relocated up here did I come to understand just what flat light is and how it can negatively affect photographs.  The sunlight striking the higher latitudes in their winter season is forced to travel through a lot more atmosphere to reach the surface of the earth because of the curvature of the earth’s surface.  This helps create the lack of shadowing and an overall ‘softness’ to the resultant light which produces a dearth of real detail.  Thus many images taken under such circumstances lack a myriad of subtle visual clues the human eye uses to establish depth of field and hence a degree of three dimensionality to the picture.  I saw this many times when I first started shooting images up here although not until I actually relocated to ‘The Great Land’ did I really see this effect in winter shots.  My eyes and brain compensate for the loss of such cues when I’m just using my normal visual reception but these clues are not reproduced in an image and hence they often look two-dimensional and tending towards a lack of contrast and monochromatic.  As good as my eyes and brain are at dealing with this situation it becomes apparent to me when just walking around this area in the depth of winter; it seems as though everything is composed of either white (snow and birch trees), green (spruce trees) or black (shadows).  The sky will appear blue when clear but it is often overcast in winter and hence it is a shade of gray.   This can be somewhat disconcerting and I can easily see how trying to land aircraft on snow under such conditions causes crashes due to the loss of reference points.

Living in the higher latitudes remains endlessly fascinating to me as there is so much about these circumstances that is quite different from those found in the lower 48.  It often seems as though so many aspects are distorted and done so in the direction of exacerbation; I now more fully appreciate way Alaska is often referred to as a ‘land of extremes’.  I find the more I’m willing to look around me with an inquisitive eye the more I find that fascinates me in my new home.
