Saturn’s Rings and the Stars of Autumn
Saturday November 7, 7 pm — until everyone gets cold and leaves
As crisp autumn nights settle in, the rising planet Saturn and the stars of fall take center stage. Ancient drama plays out overhead with Andromeda, Pegasus, Perseus and Cassiopeia. In the south Sagittarius leads us to the heart of the Milky Way, while the Andromeda galaxy is visible overhead. Join Dave Sutherland Paul Alaback and their telescopes to peer into the distant reaches of space. Meet at the Joder trailhead north of Boulder. GREAT for families - there will be step stools for smaller people to see in the telescopes. To register for updates or for any questions, contact Dave Sutherland, dsutherland4747@gmail.com. This free night program is offered through Boulder County Audubon Society.
Owl Moon: A Night Adventure into the World of Owls
Tuesday November 24, 5:30 – 7 pm Bring your holiday guests!
As the full moon rises over the prairie, leafless cottonwood trees become black twisted shapes against the sky. This is the world of the great horned owl -- a powerful and mysterious nocturnal predator. Naturalist Dave Sutherland will lead you into the moonlit world of owls on this easy nighttime hike. Meet at the Bobolink Trailhead on Baseline Road. Dress warmly and bring gloves. Bring flashlights just in case, but we shouldn’t need them. Also please bring strap-on traction for footwear (e.g. micro-spikes or yak-tracks) since the trail may be very slick and icy. This program is sponsored by Environment for the Americas and is free and open to everyone. Limit: 15 participants.

Teen Naturalists: Behind the Scenes at the Butterfly Pavilion
Sunday November 15, 1 - 3 pm
Go behind the scenes at the Butterfly Pavilion to learn about their collection of live invertebrates and what it takes to care for and manage living exhibits. Besides spending time in the “Wings of the Tropics” free flight rainforest, you’ll see where Rosie the Tarantula and a host of other small critters live when they are not on display. Learn where the living butterflies come from and how they are shipped to the Pavilion from all over the world. Entomologists at the Pavilion will answer your questions about spiders, insects, whip scorpions, sun spiders and more; and talk about careers in science, education, invertebrate conservation and living museums. Boulder County Audubon Society will pay admission for all teen participants. Families are welcome to join but will need to pay their own admission. The pavilion stays open until 5pm.

Historic Roosa Cabin Open House!
Friday December 11, 11 am - 1 pm drop ins
For over a century, the mysterious little stone cabin has sat near Wood’s Quarry at the base of the Third Flatiron. Who built it and why? Who lived here? What’s on the inside? Join the cabin’s owner Regina Bock, and Community Naturalist Dave Sutherland, for an historical “Open House” to learn the answers (to the best of our knowledge) about this enigmatic little building and get a chance to see inside. No reservation necessary, just drop by between 11 am and 1 pm on the indicated day. See the map graphic for the cabin’s precise location, right on the Mesa Trail just a bit south of its junction with the Enchanted Mesa Trail. It’s about 1.5 miles one way from Chautauqua. There is no water, electricity or toilet at the cabin.
