MNPS Field Trip: Limestone Bluffs at McMahon's Mill (Thursday)

Leader: Mary Ann Daly, Western Mountains Chapter of MNPS 

Description: Around McMahon's Mill, limestone bluffs front the Potomac with little or no land between river and rock.  Below the mill, where the towpath juts out over the river, we'll get a close look at the flora of the adjacent bluffs (without having to scale them).  We should see some cliff specialists, such as Alumroots and Allegheny Stonecrop, and limestone lovers, such as Aromatic Asters and Fragrant Sumac.  Trees include Common Hackberry, Slippery Elm, and Common Juniper, sometimes growing from clefts in sheer rock, alone or with other plants.  Staying on the towpath, we'll stroll downstream until about noon, then retrace our steps. Dues to limited parking at McMahon's Mill, we will carpool from the Downsville Ruritan Park.  This field trip involves about 2 miles of walking on easy terrain. 

Mary Ann Daly is a retired technology specialist and lifelong student of wild plants. Since moving to Washington County in 2017, she's come to appreciate the special ecosystems of the area.  

Note: There are public restrooms at both the carpool meeting place and final destination.
