Liquid Winters and Time-Bending Blooms

Long time local botanist Betty Horn sent me an email some days back--February 10, to be exact--reporting that she had just found a hepatica blooming in Herrontown Woods. Hepaticas in early February? This was news. 

Without asking, I knew nearly exactly where she had found it. If you're a field botanist, you maintain a mental map of where you've found certain special plants growing, and in Princeton, my mental map has exactly one location for hepaticas, along the ridge in Herrontown Woods. Sure enough, she had found it there, given a head start by the warmth of a nearby boulder and the snowless winter. 

Hearing the news, another botanist friend, Fairfax Hutter, checked out some hepaticas she knows of in Hopewell. No flowers, nor any buds, she reported. Betty looked back at her records and told me that "the usual time for hepaticas to bloom is early to mid March, and sometimes as late as the first week in April." 

Another early flower is snowdrops--a nonnative spring bulb that decorates the grounds around Veblen House. The first bloom I noticed this year, for the record, was on Feb. 6.

Before moving to Princeton in 2003, I lived in Durham, NC for 8 years. Winters there were much like the one we've had here in New Jersey this year. The default was no snow, and if a snowstorm did come, it became a spontaneous holiday, with schools shut down for several days. It could be said that New Jersey is the new North Carolina, with Georgia in hot pursuit, so to speak. 


The shift towards a liquid winter has made for dramatic changes in our "fillable-spillable" minipond in the backyard. It's a 35 gallon tub that captures runoff from the roof, originally conceived as a pond that could be easily emptied when our pet ducks had made it muddy. 

Like an artist who has lost inspiration, it hasn't produced very interesting ice patterns the past few winters, nothing like that stretch from 2018-19, when intermittent freezes and thaws caused it to behave like a canvas for the profound artistry of nature. Each freeze would bring new and endlessly varied patterns in the ice.

More of Nature's Art in a Backyard Minipond

The highly gifted fillable-spillable backyard minipond that receives water from the roof created more art a couple nights back. I did the best I could to give it suitable framing.



This scale-like pattern seems to be an innovation, with morning sun tinging portions with gold. The scale pattern can be seen as a miniature version of the backward "L"'s in the image above.



The artist-in-residence is content with its humble dwelling, needing nothing more than an occasional rain to keep it full.



Those flat spaces between the crystalline lines are open water, and the whole pattern could be rotated in the bowl without breaking it.


Sunlight and rotation of the photo made for a jazzy effect.



Leaves collecting in the tub hint at collage or mixed media, and may add a subtle tinting to the water over time.



An hour later, the crystals had melted away, leaving open water. Thanks goes to Leo, our dog, for getting me out in the backyard first thing in the morning.

Carnegie Hall, Carnegie Lake, Carnegie Minipond?


New York has some pretty impressive temples to the arts, this one being Carnegie Hall. These structures reach for the sky, but remain enveloped within nature's eternal Play of the Elements, with performances ranging from symphonic sunsets and cloud patterns to the crystalline miniatures of snowflakes. Light sets the mood, with water as the endlessly creative molecule so at ease in earth's temperature range, shifting effortlessly from gas to liquid to the solid state where it can really show off its range of expression. As long as there's cold weather, a breeze, or a sunset to reflect, water will offer performances at Princeton's Carnegie Lake, as well as smaller venues across NJ.

Easiest for us to access are the rainwater-fed "Carnegie Miniponds" in our backyard, which have been offering an ongoing series of exhibits.


The day after the backyard "etching" photos were taken (previous post), the fillable-spillable minipond had gained a pock-marked appearance, thus far as inexplicable in origin as the etchings.

another had these rich designs.


How does some water sitting in a tub overnight develop such a variety of shapes?


Another slight thaw and overnight freeze brought back more patterns 
like those from two days prior, 
etched by a most mysterious hand.
Thus far, no patterns repetitive enough to call "Philip's Glass".

An Exhibit of Nature's Etchings

(Preface: 2018 was a special winter in our backyard, due to the remarkable patterns and rich colors that appeared in our "fillable, spillable" minipond.) 
Our backyard artist in residence program has been going very well this winter. The artist, content to remain outdoors without lodging, has been working long hours, often overnight and in freezing temperatures, using nothing more than rainwater and a few leaves to achieve remarkable effects.



I did my best to capture the work, and give it adequate framing.

Asked how she achieved her unusual effects, and if these etchings, so different from her past works, represented a new direction in her art, she shrugged and said nothing,


then showed me a composition with etchings superimposed on what appeared to be a large bubble.



Some were more subtle than others, relying on rich undertones.

Wondering if the etching style was unique to the fillable-spillable miniponds that catch rainwater from the roof, I went to the other miniponds in the yard, created years back by digging down into dense clay. Here there were etchings as well, in a multimedia context using leaves.


Impressed, I suggested we host an exhibition, but there was no time to plan, or send out invitations. Nature, ever the restless artist, had already moved on, with rain and then snow in the forecast for overnight.

A Thousand-Eyed Grackle

With the temperature reaching 74 on February 25, I looked out our back picture window to see that our usually peaceful backyard had come alive with motion. The lawn was astir with the hyper black-winged commotion of hundreds of grackles. Their iridescent necks flashed blues, greens and purples as each probed the ground for food, with not a second to lose. Five or six stalked about on the edge of the fillable-spillable minipond, angling for a sip of water. I grabbed a camera and crept towards the window, eager to document their spectacular numbers and energy. But even my barely perceptible movements were caught by one of a thousand eyes, and off they went in a flash, a winged unison where a moment before each had been absorbed in its own pursuit of food and water. They crowded the high branches of a nearby pin oak while somehow collectively plotting their next move. Had I seen 500 birds? Or had it been one bird with 500 mouths and 1000 wings?

Graupel--A Special Form of Snow

All snow is special. Like children, except more numerous and lower maintenance, no two snowflakes are the same. As we know, snow that falls in Princeton's coveted 08540 zip code is extra special, and on the last day of January, there fell a particularly special kind of Principitation. Instead of flakes, the snow looked more like small beads of styrofoam.


When it fell one day two years ago, thinking it needed a name, I coined what seemed like a new term: snubbins. A recent google search, however, revealed that the word "snubbins" is sometimes used to refer to medium sized breasts. Who knew?

A less conflicted name came out of the blue during a trip to the Whole Earth Center, when longtime employee Bill excitedly showed me a printout from Wikipedia, describing this special snow as "graupel". To quote: "Graupel, also called soft hail or snow pellets, is precipitation that forms when supercooled droplets of water are collected and freeze on falling snowflakes, forming 2–5 mm balls of rime." These supercooled droplets, suspended high in the air and still liquid down to -40 F, collect and freeze around the snowflakes as they fall towards earth. The behavior of supercooled water came up in another recent post admiring the patterns the minipond water makes when it freezes.


In this photo of the graupel collected on our backyard fillable/spillable minipond, or mini-rink this time of year, you can see their shape. In the middle of the photo there's a snowflake still visible, only partly covered in rime.

In this photo, some of the graupel takes the shape of corn kernels.

Carnegie Ice Before the Snow


Though there are cross-over recreationists who love both skating and skiing, you know you're in the skating camp if an approaching snowstorm brings wistful thoughts of all that gorgeous Carnegie Lake ice about to get covered up.

It wasn't thick enough to skate on, but most of the lake was covered with a glistening smooth initial layer. The winter's brief history, about to be buried under two feet of snow, could be read in the rough ice that got blown into a southeast corner, on the left in the photo.

It told stories of how frozen waves formed, seeming to lap at the hibiscus-lined shore, like a Seward Johnson sculpture,

and of water's restless shifting from solid to liquid and back again, that gathered these chunks together for one in winter's long progression of still-lifes.


Our backyard minipond caught some runoff to make a miniature version of Carnegie Lake, with similar patterns of dark and light ice.

Nice to have H2O as the artist-in-residence in the backyard, with a new snow exhibit about to open, up and down the east coast.

Ice Can Be Naughty or Nice

Work with nature, or it can work against us. That's a truth whether the nature is inner or outer.


This backyard minipond swelled in recent rains, then froze to make attractive patterns.


A different scenario plays out on Linden Lane, where a sump pump discharges into the street, creating a hazard. Meanwhile, the high school's sump pump, a few blocks away, plays the role of ecological hero, discharging serendipitously and safely into a detention basin we converted into a wetland that sustains native plants, frogs, and crayfish.


A shrub like buttonbush can grow right in the water of a backyard minipond. The ice patterns arise from the slow seepage of pond water into the underlying clay, causing the ice to sag.
There's a tendency to want to get rid of sump pump water and runoff as quickly as possible, often adding to downstream flooding. More fun, and beauty, comes from a collaborative approach with nature, finding ways to use the water in the landscape.

Another Wishing (the earth) Well in the Neighborhood

Posts on a blog and letters to the editor are released into the community to an uncertain fate. Will they lodge in anyone's mind, to any effect? Irrefutable evidence came last weekend when Peter and Suzanne, neighbors around the corner, stopped by to ask about the Wishing (the earth) Well placed in our front yard next to the sidewalk. What to do with the oak leaves, which seem not to decompose at all when left on the ground. I explained the logic of the dual purpose leaf corral--a circle within a circle, with the inner circle being a central, critter-proof cylinder into which food scraps can be put, disguised by the surrounding leaves.


Peter thought about what fencing he had left over from other projects, went to the local hardware to buy stakes, and later the same day sent me a photo of their new leaf corral next to the back fence. Instead of wire fencing for the leaf-containing outer ring, it uses plastic, which is probably cheaper and appears to hold its shape just fine. Given how ideas tend to incubate for long periods, this quick turn around, from idea to reality in a couple hours, was truly refreshing.


Another neat feature in Peter and Suzanne's yard is a mini minipond, fed by sump pump water that is pumped into the small cisterns next to the house, then gravity fed to the little pond. A pink flamingo stands guard, perhaps to intimidate any great blue heron that might stop by. The screens are there to catch any heavy snow we might get this winter, and they may help discourage the raccoons and fox from stealing goldfish.

With the solar panels mounted on their roof, that means they're utilizing the sun that shines on their house, the sump pump water that comes from underground, and the leaves that fall from the trees. It all makes life, and the yard, a lot more interesting.

A Duck Gets a Taste of Spring


Our Pekin duck has been finding more reason to venture out of the coop this week. There's mud to probe with its beak, and the luxury of a bath in one of our backyard ponds swelled by snowmelt from neighbors' yards. She had no problem breaking through the thin layer of ice left by last night's freeze.

Earlier in the month, finding water in its liquid state was more of a challenge, as she took sips from the fillable-spillable minipond catching water from the roof.

She keeps a sharp eye out for hawks, turning her head to get a better look at the sky. Usually, that turn of the head means something's flying over, be it a vulture, crow, hawk, or a jet headed into Newark Airport.

Meanwhile, the duck's companion, a chicken of similar feather, was laying another robin's-egg-blue egg. We often get two a day now, as warmer temperatures and longer days have broken the winter drought.

Ducks and chickens made multiple appearances in movies this weekend at the Princeton Environmental Film Festival, particularly in the excellent documentary on permaculture, "Inhabit". The ducks were said to be excellent at keeping the slug population down on an outdoor shitake mushroom farm, and the chickens happily batted cleanup in one of the crop rotations, eating any seeds that eluded harvest.

When Snowmen Take Over the World


When snowmen take over the world, they will lounge comfortably on the patio in snow-cushioned chairs, munching on snowburgers.

Having had their fill, they will venture out to mend snowfences,

practice up for the next game of snowlax,

take a dip in the snow-lined minipond, ever so briefly so as not to melt,

and, when there is sno more for a snowman to do, take a snooze and dream of snowstorms to come.

Ducks in Snow


We didn't have tracks like these in the backyard last winter. What could they be?

No, not the robins, who paid a visit to the water tray the day before.

Not the wild turkey that surprised us with a visit last year.

Here they are. Not snowy owls or snowy egrets, but the great snow ducks of the notsonorth, heading for ...

minipond heaven, or at least haven, courtesy of the recent rains.

The ducks show far more courage than their coopmates, who are playing chicken in the warmest corner they can find.
