We estimated the number of moose (Alces alces) on the north side of the Alaska Range mountains in Denali National Park and Preserve. The 10,004 km2 (3862 mi2) area was surveyed from 10 through 23 November 2011. We observed 496 moose during the aerial survey and estimated (+ 90% confidence interval [CI]) 1477 + 238 moose for the entire survey area. Overall density was 0.15 moose/km2 (.38 moose/ mi2). The calf:bull:cow ratio was 29:53:100. We estimated that 75% of cows were without calves, 21% of cows had 1 calf, and 4% of cows had 2 calves present. Two smaller areas within the north side survey area (East and Kantishna South) were also analyzed independently.
