Not moose.
Mature bulls are about 5 ft high (1.5 m) at the shoulder and weigh 600 – 800 lbs (273 – 364 kg). Cows are smaller, averaging approximately 4 ft (1.2 m) in height and weighing 400 – 500 lbs (182 – 227 kg). An 800-lb muskox will dress out at about 480 (218 kg) lbs, providing roughly 275 lbs (125 kg) of meat.

Moose, ox, whatever. Just how are hunters supposed to get that ox off a block of ice and into a boat. :)
