Why is a rose a rose and not a mustard? Using similarities and differences to identify wildflower families

Join Dot Fears and Claudia VanWie to hone your wildflower identification skills! This short course will introduce and review the patterns and similarities of several of the local early season wildflower families followed by a hike to practice with the wildflowers we find. This will be a great way to start enjoying the new wildflower season! Meet Saturday, May 2, at 9 AM – noon at the Rabbit Mountain trailhead northeast of Lyons on North 55th Street. Be prepared for a muddy trail and typical May changeable weather. We will provide morning treats and ask you to bring your own drinks. Please register by sending an email to

Flower Adaptations to Harsh Environment

Strong winds, intense sunlight, short summers. How do so many plants survive and bloom so vigorously?  Join Dot Fears and Claudia Van Wie as we look at various strategies local wildflower have developed to survive in our sometimes challenging environment.  We will observe these adaptations first hand as we climb Caribou Hill and revel in the variety and abundance of wildflowers on this rocky, windblown hilltop. Bring your lunch and beverage for a picnic break to take in the views. Meet Sunday, June 28, at 9:00 AM at the Park and Ride in Nederland.  We will carpool up to Caribou Townsite on a dirt and gravel road suitable for 2 wheel drive vehicles, returning to Nederland at 1 pm.  Wear sturdy shoes, bring a warm jacket and rain gear for unpredictable weather at 10,000’ elevation. To register, email Please let us know whether you plan to meet us at the Park and Ride in Nederland (9 am) or at Caribou townsite (9:30 am).
