Geology of Scott’s Run


Sunday, Sept. 30, 8:30 a.m.-12:30 p.m.

Leader: Joe Marx

Audubon Naturalist Society (ANS) members $26; nonmembers $36

Scotts Run Nature preserve is a 336-acre tract of Virginia woods, ravines and palisades just upstream from the American Legion Bridge. The landscape varies from rolling upland and a narrow stream valley to rocky cliffs and riverine floodplain. The bedrock was formed in an ocean that was extinguished during the assembly of the super-continent Pangea.  One clearly visible landform in essentially a stretch mark attendant to the opening of the Atlantic. We will hike a circuit of two miles on unpaved trails that will occasionally be rocky and steep as we observe both rocks and forest.  The pace set and distance covered on our geology hikes will be faster and farther than our usual “naturalists’ shuffle.” There will also be two stream crossings on concrete “cobbles.”

Intro to Tree Identification
Friday, Oct. 12, 10 a.m.-3 p.m.
Leader: Stephanie Mason
ANS members $34, nonmembers $48
Fall is a great time to learn to identify trees and shrubs. With brilliant leaves highlighting the twigs, new buds already formed, and many fruits hanging on, there are lots of distinguishing features that help sort out the various species. This program at Woodend Sanctuary will begin indoors with a look at some techniques of tree identification, coupled with practice using a simple key. Outdoors use your new skills to identify many of the trees growing on the grounds. Both beginners and those who want to brush up on their ID skills are welcome.

Fall Fungus Walk
Sunday, Oct. 21, 2-4:30 p.m.
Leader: Tovi Lehmann
ANS Members $24; nonmembers $34
Fall is a great time to learn to ID some of the most common families of fungi and their role in the ecosystem. At a local natural area, explore the natural history of your fungal neighbors. Note: this outing will focus on natural history of fungi species, not their edibility.

Window into the World of Fungi
Thursday, Nov. 1, 7-9:30 p.m.
Leader: Tovi Lehmann
Free, but registration required.
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 lecture at the ANS Woodend Sanctuary, explore the natural history and ecology of local fungi neighbors. Edibility is not featured. REGISTER ONLINE.

Fall Leaf Drawing Workshop


Monday, Nov. 12, 10 a.m.-3 p.m.


Leader: Tina Thieme Brown

ANS members $32; nonmembers $44

There is a long tradition of naturalists keeping field notes, often accompanied by drawings. Learn how to add sketches to your field observations at a workshop at Woodend Sanctuary. Tina will lead you on a walk in the woods, where you will carry along your sketchbook and reflect on the changing season. Returning to an indoor classroom, she will guide you through the steps to create a drawing of fall leaves and acorns. The only experience required is a love of nature, and a desire to look closely at the seasonal changes in native trees. A suggested art supply list will be provided with confirmation letter.

Geology at Long Branch
Saturday, Dec. 1, 1- 4 p.m.
Inclement weather date: Sunday, Dec. 9
Leader: Joe Marx
ANS members $26; nonmembers $36
Arlington’s Long Branch Nature Center occupies a picturesque spot overlooking a short, misnamed tributary of Four Mile Run, itself a tributary of the Potomac. Hike a mile or so out–and a mile back–down Long Branch and Four Mile Run, returning by the same route. A variety of rock units are exposed along the trail, including an undersea landslide frozen in time, long-vanished seaside flats, and the bottom layer of the coastal plain. To add botanical icing to our geological cake, we will traverse an old-growth upland forest and a quicker-changing floodplain forest. The paved route is entirely on level to gently inclined park trails.
