JULY

Geology at Great Falls, Maryland  FULL
Saturday, July 12 (8:30-11 am)
Leader Joe Marx
Members $20; nonmembers $26
People in our region find Great Falls both fascinating and perplexing. Arguably our most dramatic landscape feature, its origin and development remain obscure to many. We will take a short and easy walk from the Great Falls Tavern Visitor Center to the falls overlook, a round trip of about a mile. During the walk, we will discuss how the bedrock of the Great Falls area formed in tectonic collisions hundreds of millions of years ago and how the waxing and waning of the continental glacier led to the much more recent creation of the falls. There should even be time to examine the flora and birdlife along our path. Registration required, please use registration form.

spicebushBotany by Nose
Sunday, July 13 (8:30-Noon)
Leader Carole Bergmann
Members $24; nonmembers $34
While most of us rely on visual clues to help us identify the plants that comprise our landscape, our sense of smell can be an important, complementary tool. Anyone who has broken a Spicebush or Black Birch twig can confirm that. Our outdoor classroom will be Little Bennett Park near Clarksburg, MD, as we “scratch and sniff” our way through woodland and wetland habitats. Registration required, please use registration form.

Window into the World of Fungi
Thursday, October 16 (7:30-9:30 pm)
Saturday, October 18 (9 am-1 pm)
Leader  Tovi Lehmann
Members $42; nonmembers $58
Lecture only $20/$28
Rooted, yet not plants, heterotrophs, but not animals (growing in fairy rings, yet not even fairies), fungi are members of another kingdom. Mostly hidden under the surface, fungi have evolved their own solutions to life’s persistent problems. Gaining the recognition for their pivotal role in shaping the living world, they now reshape fundamental perceptions of biologists. In this workshop, we will explore the natural history and ecology of our local fungal neighbors, rather than focus on the edibility of particular species of mushrooms. Our field trip will visit a close-in natural area chosen by the leader, based on his scouting closer to the program. Register online.
