Big Game Records
The Boone and Crocket Club - founder of the National Park Service and the duck stamp program - maintains a big game records program as a way to track conservation success and the pursuit of healthy, balanced herd populations. They keep records for 38 categories of game in North America (including six Alaskan species) and hold an awards ceremony each year to recognize the trophy kills for that year.
When you're ready to go after your own big game trophy in Alaska, be sure to check the Alaska hunting regulations for information about seasons and rules.
Many of the standing World's Records are held by hunters in other North American locations, but a good number are from Alaska, as could be expected:
Alaska brown bear, measuring 17 15/16ths (jaw) and 12 13/16ths (skull)
Kodiak Island, 1952
Dall sheep, with horn length 48 5/8ths
Wrangell Mountains, 1961
Polar bear (now protected), with skull length of 11 7/16ths
Kotzebue, 1963
Sitka black-tailed deer, 6 points (left) and 5 (right)
Control Lake, 1987
Alaska-Yukon moose, 19 points (right) and 15 (left)
Fortymile River, 1994
Barren ground caribou, 25 points (left) and 17 (right)
Iliamna Lake, 1999
In order to qualify, an official measurer must carefully assess your kill using a system that heavily emphasizes symmetry. The Boone and Crockett Club will send a list of measurers for your state if you contact them by email (bcclub@boone-crockett.org) or phone (406-542-1888).
A collection of big game trophies is on display at the Buffalo Bill Historical Center in Cody, Wyoming.
The state of Alaska also keeps records of harvests, and filing a report is mandatory for all hunters. You can access past harvest records for all species, by Game Management Unit, here: http://wildlife.alaska.gov/index.cfm?adfg=harvest.main
