The North American 27, or "Super Slam" as coined by Chuck Adams, includes:

Grizzly Bear, Black Bear, Polar Bear, Brown Bear, Woodland Caribou, Barren-Ground Caribou, Mt. Caribou, Quebec-Labrador Caribou, Dall Sheep, Stone Sheep, Rocky Mt. Bighorn Sheep, Desert Bighorn Sheep, Pronghorn Antelope, Rocky Mt. Goat, Mule Deer, White-tailed Deer, Coues Deer, Columbia Black-tailed Deer, Sitka Black-tailed Deer, Alaskan-Yukon Moose, Canada Moose, Shiras Moose, Roosevelt Elk, Rocky Mt. Elk, Musk Ox, Bison, and Cougar.

Other organizations (e.g. Safari Club International) recognize more species than those listed above-such as Wolf, Tules Elk, Desert Mule Deer, and Wolverine to name a few.

I have been chasing the North American 27 since 1992. Currently, I'm 14 animals intomy goal of all 27 (see bold type above). It has been a fun journey. I would recommend the pursuit of these 27 "Super" animal in a heart beat. You won't regret the chase-even when you come home with nothing!
