                      When the fires of August 2000 roared across the Bitterroot Valley and up over
                      the Continental Divide, they left behind an intriguing relic exposed in the
                      ashes high in the Anaconda-Pintler mountain range.
                          The discovery by one of the fire mop-up crews of a bison skull at over
                      8,000 feet triggered some interesting questions about what a plains bison was
                      doing in a high-elevation forested zone so distant from any typical habitat. Did
                      this animal represent something more significant than a wandering oddity?

          It turns out that                                                                                                     drives the life and

   New Summer Camp Offerings!
   Every summer, MNHC connects hundreds of kids to nature through our Outdoor
   Discovery Day Camp programs. Our camps feature daily field trips, skilled
   instructors, unique opportunities to connect with scientists and naturalists, and
   lots of time for exploration and play in the outdoors.
   This year, we’re proud to respond to community demand by offering even more
   summer options for younger and older campers alike—from new half-day programs
   for elementary-aged campers to special in-depth experiences for middle schoolers.
   We’re also offering new adult-child guided Naturalist Camp Days to help kids and
   their parents, grandparents, or other caregivers explore Montana’s nature together.
   You can learn more and register for camps on our website:

   Join us for our exciting new program! From November-
   April, on the second and fourth Wednesdays of the month,
   community members of all ages can stop by MNHC and
   spend a couple of hours drawing, sketching, and painting
   specimens from our collection, with techniques and
   guidance from MNHC naturalist and artist Jenah Mead.
   The program is free with admission or membership, and
   we provide drawing materials (though we do encourage
   participants to bring their own inking and painting
   supplies). This popular program is a wonderful way to
   develop and hone your artistic skills with the guidance of
   a talented artist, and a great opportunity to study natural
   history specimens as well. Come draw with us!
   We may offer a slightly different version of this program
   outdoors this summer as well—stay tuned!

The Joy in Environmental Education
At the Montana Natural History Center, we get people excited.
Specifically, we get them excited about nature and how amazing
our environment is. (I mean, it sounds pretty nerdy, but learning is
actually really fun.)
       I think back to late last year when Ben Goldfarb, author of
Eager: The Surprising, Secret Life of Beavers and Why They Matter,
gave a lecture at the Center. My wife, who I can say went into the
evening skeptical about such a topic, ended up having a wonderful
time learning about how amazing beavers are and why they are so                              Alyssa Giffin                      BY ALLISON DE JONG
