Join us for the 15th Annual Moose Day!

Scroll down to check out the map of this year’s sightings or send us an email if you are interested in volunteering.


It’s that time of year; Moose Day is coming up on February 25th, 2023.

We are especially in need of strong skiers to cover the sections in the northern end of Grand Teton National Park and the west side of the Tetons. If you are a skier who lives in or is willing to travel to Teton Valley for Moose Day, we would love to enlist your help survey the canyons and creeks in Wyoming that are more accessible from the Idaho side (Darby Canyon, Moose Creek, etc.).

If you plan to participate with a friend or family member, that is fine, but we do require at least one party member to be a certified Nature Mapper. If you are not a Nature Mapper, you MUST ATTEND A NATURE MAPPING TRAINING PRIOR TO PARTICIPATING IN MOOSE DAY. Our public training prior to Moose Day is February, 8th.

If you know someone who may be interested but is not yet a trained Nature Mapper, please have them email for more information on becoming certified and collecting these important data for WGFD.

Pre-Moose Day ID Clinic and Education Seminar

If you haven’t emailed Hilary about your intent to attend the Moose Day Identification seminar with Wyoming Game and Fish biologist Aly Courtemanch on February 13th at 6 pm, please do so. You don’t have to participate in Moose Day to attend the seminar.

In the seminar you will learn about Moose identification and biology, the status of the Jackson Moose Herd, and the history and purpose of Moose Day. Please email to register so you can receive the Zoom link for the seminar.

The Challenge

Gathering information about ungulates such as moose serves many purposes in Jackson Hole. Wildlife biologists concentrate on public lands when they survey Jackson Hole’s moose populations. Recording observations of moose throughout the valley and adjacent to developed neighborhoods helps us understand how to live compatibly with a treasured species of wildlife. While valley citizens can often feel disconnected from wildlife management decisions, the annual Moose Day survey is a great opportunity to contribute directly to our collective wildlife knowledge.

The Solution

Certified citizen scientists of Nature Mapping Jackson Hole track moose on pre-assigned parcels on Moose Day – an annual survey conducted in collaboration with the Wyoming Game and Fish Department (WGFD), Grand Teton National Park, and the Bridger-Teton National Forest. Teams of two or three people get an assigned territory in areas that are difficult for the WGFD to survey (mostly near private lands or adjacent to more developed areas) and record moose observations. These collected data contribute to monitoring moose population trends in Jackson Hole over time. A winter’s day searching the valley for moose is one of many exciting Nature Mapping Jackson Hole projects that connect members of the community to one another and to our wild lands.

Moose Day Protocols

As a citizen science program, Nature Mapping Jackson Hole requires careful collection of data in order to maintain quality output. The following Moose Day protocols are designed to assure that all volunteers collect data in a consistent manner.

  • Cover your area as thoroughly as possible between dawn (7 am) and noon.
  • Record moose only for your area. If you observe a moose in another area, you can make the observation, but put in “Comments” that it wasn’t seen in your area.
  • You are welcome to make “Casual Observations” of other species, time permitting.
  • If you find an area where you suspect someone is feeding ungulates (e.g. a large # of animals congregating in one spot), please let us know. We are trying to increase our educational efforts around this issue as it may contribute to increased wildlife vehicle collisions.
  • Covering your area can be done by any means that are appropriate for your area (car, skis, snowshoes, etc.). Please display the Nature Mapping Moose Day sign on your vehicle.
  • If you do not have a partner, please let the volunteer coordinator know. A second set of eyes is critical to help you search. More than two people are fine. We’ve found that the success rate increases tremendously with a second set of eyes especially for those routes that are
    primarily automobile-based. And also if you are skiing it is important for safety.
  • Please keep track of time spent searching and how you traveled. For example: 3 hours total: 1 hour on skis + 2 hours by car. Please email this information to Frances during the week.
