CMZoo Alaska moose Atka will be strutting a new “minimalist” look for the next few months. As most male moose do each winter or spring, our 3-year-old Alaska moose, Atka, has shed his antlers!

We want you to guess how much they weigh for a chance to meet Atka up-close. Use the form below to enter your guess for the combined weight of both of his antlers. One person who guesses the closest combined weight of his antlers will win a 30-minute encounter with Atka for up to four people. (See Contest Rules below).

This contest is now closed.
Drumroll, please! Atka’s antlers’ weight is in.

  • The combined weight of Atka’s antlers was… 14 pounds and 13 ounces!
  • 1,271 people submitted guesses through our online form, and we’re thrilled to see so much enthusiasm for Atka. Thank you for participating and for celebrating Atka’s annual antler shed in such a fun way.
