We took turns and it still took a solid 20 minutes to get thru. Plus the last 2 ft had to kneel, no extension.
PLUS it was a high lake at 12,200 ft elevation. Never got a bite.
The last sentence of this post could be used to coin a new phrase - HYPOXIA SKUNK
When I was in the best shape of my entire life in my mid-twenties, I made 15 holes through 32" black ice with my 8" MORA, and the blades were not close to brand new ( they were the high quality Swedish ones though ). I was drilling like a crazy person, showing off some for a couple guys making their 1st trip with me. I barely rested between holes and got all 15 done in 45 minutes, NOT A TYPO.
I was a pretty hard core gym rat back then and would often do reps with the weights at the gym until I became nauseous.
When I got done with the 15th hole that day I was stripping down to just a sweat-soaked tee shirt in 5 degree F temp, - the steam was pouring off from me like a locomotive for about 10 minutes.
