Your cork obviously doesn't float quite right, Bristoe...
10" ice- bits are the norm - and sometimes that's a tight fit (shee fish can get to 50 lb). I'm missing it already, having moved south awhile back.
The first time I went shee-fishing, I had 7 fish in 30 minutes or less. If they are biting, "45 minutes" is plenty. I have headlights on the snowmachine. Even on the shortest days 500 miles farther north (Barrow) , one has 4 or 5 hours of semi-lilght. the sun is only below the horizon for 5 weeks or so there.. In Kotzebue, 30 miles north of the Arctic Circle, where this pic was taken, it's only a few days - and a good 6 or 7 hours of "light".
As Staley Foster, an Eskimo who showed me how and took this picture for me said, "It ain't always like this!" He had about 15 fish by that time (better spoon) , and hang the nominal daily limit of 10.
True, there were less productive times... but when you can walk on water, it's all good.
