Geology Tour of Tregaron on November 15 from 1 – 3 p.m.

Back by popular demand, Tony Fleming, a renowned professional geologist and hydrologist who grew up one block from Tregaron Estate and is the author of the modern geological map of the District, will lead a fascinating tour of Tregaron's natural history. We will meet at the top of the north meadow (aka "sledding hill") at 1 p.m. for a hot beverage while Tony gives an overview. Enter either of Tregaron's entrances at 3100 Macomb Street or 3029 Klingle Road; walk up the driveway to the top of the hill.

Below are excerpts from Tony’s program: Tregaron is an incredible neighborhood resource. With its deep ravines, old woods, and elegant landscape architecture, Tregaron is singularly responsible for much of the environmental ambiance that defines this section of Cleveland and Woodley Parks. Tregaron is a veritable showcase of geologic and ecologic features and processes that include outcrops of some of Washington’s oldest rocks, unusually large crystals, an ancient channel of the Potomac River, architectural use of native building stone, a biologically diverse landscape, and many environmental issues related to the interface of water and infrastructure in the urban environment.

A description of the tour: This leisurely loop hike will showcase a wide variety of natural features, landscape architecture, and environmental issues, with time for questions and discussion. Did you know that the local bedrock was not originally part of North America? That giant crystals of hornblende and staurolite occur on the property? Can you tell the difference between native plants and invasive non-native ones? Why is Klingle Road so flood-prone? The tour will highlight all of these topics and more!
