Here is a nice set of Koyukuk moose horns a hunter just left with the gut pile. Granted it was 20 years ago. It's hard to imagine leaving this set lie. You can't eat the horns, and there is a fair amount of work involved hacking them off the head, and hauling them out. But these were just left behind.(gut pile was a week old when the horns were found).
Guy that found them is my Alaska mentor. Got me started moose hunting talking me on my first two moose hunts, and helping me kill my first two bulls, leaving me hopelessly addicted to Alaska moose hunting. Amazing the impact those early hunts have on young people.
I took my son this year. We traveled 40 river miles(10 of it upstream dragging canoes in shallow water).. hunt of my lifetime. Alaska is simply a paradise. Our moose from this year.. rope come along and an hour later and he was high and dry on the rock beach and cooling out nicely.. we took the horns out.. not as "evolved" as the hunter that left the above set.
