MNPS Field Trip: Limestone Bluffs at McMahon's Mill (Thursday) (09/17/2026)

Thu, 17 Sep 2026 14:00:00 GMT

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.

ONLINE REGISTRATION IS REQUIRED. Limited to 14 people. Registration through August 31 for members only. Directions will be included in registration confirmation.

Cancellation Policy: the trip will proceed in drizzle, but will be canceled if heavy rain or thunderstorm is forecast; cancellation will be emailed at least 2 hours before meeting time.
