/in , /by

New on-line CE opportunity for FMN.

When: Thursday evening, March 7th at 7pm.

Presenter: FMN Susan Farmer is a longtime Blue Bird nesting box monitor at Huntley Meadows and a member of Virginia Blue Bird Society.

River Farm Blue Bird Boxes and a Ha-Ha.

/in , /by

January 13, 2024 – FMN was able to kick-off the stewardship activity to replace and monitor the Blue Bird Boxes at River Farm.

FMN Susan Farmer with Bob Farmer

Susan Farmer is the FMN coordinator for service and citizen science activities at River Farm. When the American Horticultural Society (AHS) notified her that the donated boxes were in, she organized FMN volunteers to help Jack, the River Farm groundskeeper, with installation. Eight boxes were replaced and ten sad boxes were removed and salvaged for parts.

The long-term plan is to officially monitor and maintain the boxes. To officially monitor and report hours to the Virginia Blue Bird Society requires training, so Susan is arranging that for early March. Susan is also creating a presentation for an FMN CE program. Along with general history of bluebird trails and how they have helped bring back the bluebird, she will discuss specifics on the River Farm opportunity.

As an aside to this … notice the Ha-Ha Wall (or saut de loup) behind the chain in the river view photo. You don’t see it? That is precisely the intended illusion. These walls are a feature developed by the French in the 1600s. Chateaus and estates would incorporate Ha-Has in landscape design to prevent access to a garden by, for example, grazing livestock, without obstructing pastoral views. I’ve seen these now at Gunston Hall, Mount Vernon, and here. River Farm was once owned by George Washington.

For the garden design enthusiasts among us … the name Ha-Ha was first used in print in Dezallier d’Argenville’s 1709 book, The Theory and Practice of Gardening. He explains that the name derives from the exclamation of surprise viewers would make on recognizing the optical illusion.

Mount Vernon incorporates Ha-Has on its grounds as part of the landscaping for the mansion built by George Washington’s father, Augustine Washington. President Thomas Jefferson built a Ha-Ha at the southern end of the South Lawn of the White House, which was an eight-foot wall with a sunken ditch meant to keep the livestock from grazing in his garden. Yes, livestock used to graze the White House lawns.

A 21st-century use of a Ha-Ha is at the Washington Monument to minimize the visual impact of security measures. After 9/11 and another unrelated terror threat at the monument, authorities put up jersey walls to prevent motor vehicles from approaching the monument. The temporary barriers were later replaced with a new Ha-Ha, a low 30 inch granite stone wall that incorporated lighting and doubled as a seating bench. It received the 2005 Park/Landscape Award of Merit.

But I digress … we had a great winter’s day start to this wonderful stewardship opportunity at River Farm. Thank you to the 7 FMN that helped Jack on installation-day. We look forward to working with other volunteers and staff to learn more about River Farm and grow this partnership in 2024.

As part of FMN Chapter Project at Mason Neck State Park, FMN budgeted funds in 2023 to assist the Park maintain its pollinator gardens.  The Park requested that we use the funds to purchase equipment that will assist with that mission.  We delivered a gorilla garden cart, a Stihl battery-operated weed whacker and a battery-operated hedge clipper to the Park on January 7, 2024.  Shown with the equipment are Chief Ranger, Visitor Services Jaime Leeuwrik (also our Chapter’s Co-Advisor) with Ranger Alex Dullea accepting our donation.

Our Chapter Project has been dormant but will soon resume activity.  If you are interested in designing informational signs, please join us.  Contact Sarah Mayhew for details ([email protected] with MNSP in the subject line).

We will soon begin garden workdays.  Since we are joined by volunteers from the Friends of Mason Neck State Park, our sign up for these workdays will be via a Sign Up Genius link.  It will be posted to the Google Group with workdays expected to begin in early March.  For more information, contact Sarah as above.

The Petroglyphs of Great Falls, Virginia

Article and photos by FMN Stephen Tzikas

Early in my career I had numerous business trips to the southwest border of the country, and on my personal time, I visited the national or state parks in the area that had petroglyphs.  I found these fascinating, because they are the communication record of the indigenous people of the area. I think most people associate petroglyphs with the southwest of the country, but one can find them on the East coast too, including Fairfax County.

The Safe Harbor Big and Little Indian Rock petroglyphs are an archaeological site located at Conestoga Township in Lancaster County, Pennsylvania. It consists of two rock islands located in the Susquehanna River. Big Indian Rock is 60 feet by 40 feet, and has carvings on all sides. These Safe Harbor petroglyphs are the largest concentration of ancient Native American rock art sites in the eastern United States.  In June 2000, I had the pleasure to venture out about a half mile by small canoe to the petroglyphs with the expert archaeologist on these rock symbols.  He was interested in my astronomical, folklore, and Jungian psychology interpretations as they related to the archaeological record. The petroglyphs of this location easily rival those in the southwest.

The wider area of the Great Falls petroglyphs.

The Fairfax County petroglyphs are located in Great Falls, along Difficult Run, walking from Georgetown Pike.  They show a series of a man with a spear being thrown with an atlatl. The atlatl existed prior to the bow and arrow, so the petroglyphs are likely 500+ years old to about 5,000 years old. They are very weathered so in my opinion they are in the older range of estimates. Petroglyphs are powerful

anthropological archetypes that are central to the culture that lived in the Great Falls area at the time. Think about how you as a person are defined by all the cultural symbols around you, and then you can better appreciate
