Mapping the Balance between Imagination and Precision

My teaching colleagues and I–and here I’m counting parents among my colleagues–wanted students to grow into a sense of place that would begin local, and widen to the universe. We wanted that sense of place to be both intimate and informed: to have the tugging anchor of subjective personal experience; to have also the power and legs for traveling, the reliability, the sense of responsibility, of objective information and understanding.

For me, these different flavors in my sense of place come together in maps. That may be partly because of the ways I’ve experienced their use. In an early memory, my mother introduces me to our new house, not yet built, by telling a story using the blueprint: “Here you’ll come in the door, and here you’ll put down your lunchbox…” In a slightly later memory, we use a map of the world, posted on the kitchen wall, to trace our father’s travels.

map array with pinsWanting to give my students what had meant so much to me–especially at the beginning of every year, when they particularly needed sense of place–I filled my classroom with maps at every scale. Needing more wall space, I put maps out in the hallway, like a party spilling over. Showing someone a map, for me, is as happy as giving someone a book.

Maps choose what to show, and fall short of the truth by leaving things out, sometimes with intent to deceive, but often because there’s no escaping it. Realtors’ maps aren’t likely to show the things nobody wants to live near, the incinerators and Superfund sites–but every map on a local scale has to choose which tiny streams to signify with a blue line, and which to leave unknown, secret to everyone except the kids who play in those woods or that back lot.

mapping black and white aerialAn aerial photograph lies, too. For one thing, it flattens. In my classroom an aerial photograph of the landscape around our school helped us locate ourselves in this place we shared, but gave no real sense of the sizable hills many of my students crossed to get to school. (The map above isn’t the one from my classroom. On that one the school wasn’t labeled, and people had to work a bit, using whatever clues they knew, to find it. If you’re at all familiar with that area, though, you know about the hills that have vanished in the aerial photograph’s view.)

mapping topo UptonTopographic maps show contour much better. Once students knew how to interpret all those swooping lines, they could observe how the rivers wound their way between the hills, along the low points; how the river stretched out and wagged around in flatter places, like the route of the West River just a mile or so from school, where it moves slowly through swamp.

We talked about latitude and longitude and the trickiness of showing a spherical earth on flat paper or a flat screen. All that map literacy helps kids make sense of maps, and appreciate their precision. Beyond that, though, we gave kids lots of opportunities to explore the correspondence between a map and the world it shows–lots of chances to line up the street view and the overhead view; the labeled and boundaried with the geographic and unbounded; the subjective and the objective.

For starters, we posted combinations of maps and aerial photos on many scales. Here are a few:

  • a blueprint of the school, or the plan of the school on its property, compared with the Google image from overhead
  • the aerial view and topo view sampled above
  • a satellite photo of eastern Massachusetts posted near a highway map
  • the blow-up beach ball earth, that swirled blue-green-white marble the astronauts see, compared with the traditional globe in its wobbly frame (which always reminded me that the political earth is fragile and precarious.)

Our Places Max 2bWe read Vera B. Williams’ Three Days on a River in a Red Canoe, and thought about the role of maps in that adventure. We made maps of our own places, emulating the kids’ maps in My Place, the remarkable Australian book about sense of place, created by Nadia Wheatley and Donna Rawlins. 

We put maps into field trip packets, so the kids, often riding with drivers other than their parents–and some of them a little nervous about that–could take control, in a way, and follow our route from highway to highway, from Grafton to Sturbridge or Lowell or Pawtucket or Cape Cod.

On the giant topographic map array with which we started each year, kids narrated their routes from home to school, or from home to a friend’s house. Kids who lived in two houses for parts of every week marked them both and looked at the route between them. Samantha Cook, now a grown-up, once said: “No matter what I want, it’s in the other house.” Don’t all of us have something like that in our lives? The distances and relationships maps show us can be deeply personal, an objective correlative for a felt experience.

In general, whenever we compared a map and a place, using the one to help us understand the other, and vice versa, we were balancing, weaving together, precision and imagination, as all authentic human learning must.

Precision does matter. A map fails us if it isn’t as faithful as possible, and a gratuitously misleading map leaves us not just lost, potentially, but also with less power as citizens trying to take responsibility for our places. I’ve written elsewhere about a wonderful book by the Canadian writer Val Ross, in which she describes the lengths people have gone to in order to get increasingly accurate maps of the places that matter to them.

I thought of Val Ross last week, and wished again that she were still within the reach of earthly communication, so that I could send her an article one of my past students posted on Facebook–about the iconic outline map of Louisiana, black on white, shaped like a boot, found on signs everywhere throughout Louisiana.

mapping Louisiana

Throughout Louisiana, and beyond, that image of the state can be found–but not in the parts of the map that aren’t land any more. There, anything that could hold a sign–a post, a tree, the side of a building–is gone, underwater.

The altered map shows what Brett Anderson figures actually remains of Louisiana. He and his colleague Jeff Duncan want a truer public map, a truer icon, in order to focus public attention on land loss. The disappearance of Louisiana’s land results partly from natural changes, but it’s also an outfall of corporate actions, poor planning, political corruption–things that can be changed by active citizen involvement.

Active citizen involvement on behalf of place needs the nourishment of sense of place. It needs not just one good map or aerial view, but many, showing the present, showing the past, showing the hills and rivers, showing the town lines down the middles of the rivers, showing the connections.

I think of teachers in Louisiana, trying, as middle school teachers everywhere do, to use the increasing perspective and cognitive reach of that age, and help students see the relationship between the map and the world. I feel for all of them; we have a harder job when that relationship is broken.

mapping bike trail map editSo here’s a cheer for classroom maps, maps in books, maps posted out in the world, accurate and ready and waiting to be shared. The other day, my husband and I grinned at each other when we came to the end of our bike ride and saw two women standing at the large posted map of the trail. They were telling the story of the ride they’d just taken. “We parked here, and this is where we saw the swan, and this is where we stopped to talk with Joe–”

The map was helping them know their own lives more vividly and clearly. We all need that.

Chasing the River

As a teacher learning along with my students, I met Donna Williams, watershed wizard at the Massachusetts Audubon Broad Meadow Brook Conservation Center and Wildlife Sanctuary. She told us that the word watershed means the area from which rainwater or snowmelt drains into a particular body of water. You’re always standing in a watershed, even if your feet are dry.

Watersheds are often split by town or state boundaries, complicating efforts to protect them. Before the Blackstone River could be cleaned up in any significant way, the watershed of the river, draining large areas of both Rhode Island and Massachusetts, had to get over those political identities, and some economic rivalries, too, and start thinking like a watershed, an area with a lot to gain by working together. Knowing about watersheds can help us understand both the organization of ecosystems, and the impact of environmental damage–and environmental improvement.

To make it even more interesting, we live in watersheds within watersheds.

When my hillside gets a heavy rainfall, whatever doesn’t soak into the ground runs downhill into one of several small brooks which braid together to be called Indian Brook. So I live in the Indian Brook watershed.

A couple miles downstream, Indian Brook runs up against a dam and forms the Hopkinton Reservoir, in Hopkinton State Park, which looked like this on September 18, 2013, at a time of low water and not much color yet in the leaves.

After it emerges from the reservoir, Indian Brook twists and turns some before it runs into the Sudbury River, near the tracks for the MBTA train to Boston. Meandering through Ashland and Framingham, the Sudbury runs beside the Massachusetts Turnpike briefly, then heads north, through the marshes of the Great Meadows National Wildlife Refuge. In Concord, the Sudbury joins up with the Assabet River at a place called Egg Rock, to become—presto change-o—the Concord River.

This photo of Egg Rock was taken in 1904 by Alfred Sereno Hudson [Public domain, via Wikimedia Commons] from the very beginning of the Concord River, with the Assabet to the right, and the Sudbury out of sight to the left.

By the time it gets to the Concord River, my backyard runoff is traveling with that of many of my past students, from Hopkinton and Southborugh and also from Westborough, Marlborough, Northborough, Sudbury, and Wayland. The story isn’t over, though, until we get to the ocean.

In Lowell, the Concord joins the Merrimack River, saying hello to a tremendous share of the runoff water from New Hampshire and central Massachusetts. Go check on Wikipedia: http://en.wikipedia.org/wiki/Merrimack_River, and you’ll see what I mean, unless someone takes the map down. Hundreds of thousands of people live with me in the Merrimack watershed. Of course, for a humbling comparison, you could check out how much of North America is drained by the Mississippi.

Anyway, back to New England, all these waters head for Newburyport and the Atlantic, shouting for glory as they go, especially in flood season.

Many explorations opened up this story for me: walking parts of my watershed pathway, canoeing other parts—swimming in some places!—and tracing all of it on maps.

Like so many explorations in my life, this one started with something a student wanted to do. For a big individual report, David Gelman wanted to ‟chase” his own watershed pathway. Here’s something interesting: although David and his family lived only a couple of miles from me, his pathway was completely different, and led to the Atlantic via Narragansett Bay in Rhode Island.

While everyone else was reading books, David and I sprawled on the floor to read topographic maps. Step by step we figured out which body of water led to which, using the topographic contour lines to make sure we were headed steadily downhill, the way water does. At the same time, we figured out all the places where roads followed, or where bridges crossed, the succession of brooks and ponds that led David’s backyard runoff to the Mill River and then the Blackstone River.

Armed with that information, David and yet another amazing Touchstone parent, his mother Rosemary, went adventuring, ‟chasing the river.” They managed to find almost every road crossing of their watershed pathway. At each stop they did simple visual tests for water quality, and took photographs. Their thoroughness was inspiring to everyone else, and deeply satisfying for them.

David wound up knowing something about his place in the world that I wanted more kids to have a chance to know–and more grown-ups, for that matter, beginning with myself.

This stream of thought (I couldn’t resist) could go on for quite a while–It would take much more than one blogpost to tell about everywhere that led. Think of your power, David, wherever you are!

Next time, finally, I’ll jump forward to the 2012-2013 year, when we were studying New England, and did some work with watersheds using Topo software. Down by the virtual riverside.

Mapping the community

One of my grandfathers died when I was not quite two years old. Photographs show me sober-faced and blonde on his lap—but I can’t consciously remember him. As I was growing up, though, I treasured stories about him, souvenirs, evidence of any kind.

I remember a wall covered with maps which my grandfather had joined together, to show a wide area of many towns centered around the Maine farm he and my grandmother bought in the late 30s, when the world seemed to be falling apart. To make this map collage, he had used USGS topographic maps, first bought (pre-farm) for fishing trips, for knowing the ways of brooks and ponds. Tiled together, the maps gave both a huge view, and detailed views–the paths of the largest rivers, and the wiggles of the tiniest brooks, all on the same wall.

Fast forward many years, during which I grew up in a house with more maps on the walls than pictures, and then married a man whose idea of unpacking, after a move across several states, was to open a box labeled MAPS in the middle of the night, and put up a good selection. The Pisgah National Forest on the bathroom door; a map of the known universe on the wall of the dining alcove. Etc. (Some other wife might have been less pleased.)

milford quad smallerFast forward again through several other kinds of work, and find me, eventually, teaching classes of kids from towns all over central Massachusetts and the northern corners of Connecticut and Rhode Island. I wanted to help them know where they were all coming from, and use that as a start for thinking about the worlds we didn’t share and the worlds we did.

It was my husband who said, ‟You could get a whole lot of USGS topo maps.” And it was my memory of my grandfather that said: in a classroom, there are really large walls.

For years, then, a new school year officially began for me when we put the maps back up.

map array smallerI arranged the array of maps, still folded, on a table, and then handed them one by one up to my husband where he stood, somewhat precariously, on a counter below the largest bulletin board space. I folded back the margins to the edge of the map itself; he worked to make the edges of the maps match up as well as possible, so that roads, in red, or brooks, in blue, or town lines, in black, wouldn’t stagger from one map to the next. We marveled again—him from two inches away, perched high; me from the middle of the room—at how much of our relatively urban state was still woods (in green) or swamp (stippled with those funny little swamp symbols.)

Enter students. I usually began, the first week of school, by encouraging kids to compare the map array with the satellite photographs hung nearby. Those big purplish splotches on the maps matched up with cities easily visible from space. The major highways, 9 and 90 and 495 and 290, showed as arteries on the satellite photos also.

But then we zeroed in. If their houses or apartments or condos weren’t too new, and if they didn’t live in downtown Worcester, kids could find on this public document a piece of their private lives: their homes, in the form of tiny black squares. We marked each student’s place with a flag pin specially augmented with page markers, to hold their names.

Here’s most of one year’s map flags:

map array with pins

The kids who lived at the top of the array, up near the ceiling, had to call instructions to a grown-up climber, but the kids down in the nether regions of the Blackstone Valley could stand on a low stool and place their own map flag, sometimes finding the pinprick left by an older brother or sister in a previous year.

Students who lived in city neighborhoods or new houses—or, oftener and oftener, as the years went by, on brand new streets—had to look carefully at nearby streets and intersections, tiny ponds back in the woods, the shapes of hills given away by topographic lines, in order to see and mark where their houses would be. Sometimes it helped to replay the trip home from school: and here we turn left, and that’s where the old drive-in theater is.

Kids whose parents lived in different houses generally chose to mark both. Parents came in during morning sketching, to clarify confusing locations. Other grown-ups wandered by, and pointed out their own landmarks.

As we traced routes between each others’ houses; as we figured out who lived furthest from school, and who closest; as we crossed bridges and followed off-ramps—all of us developed increasing fluency going back and forth between our knowledge of the three dimensional world, and the abstraction of a two dimensional map.

Like a story, a map shows relationships that we didn’t realize before; it also leaves out things we know better than it does. We need the map and the map needs us.

Next post, I think, we use maps to chase rivers. My grandfather would have approved. Andrew working with Topo cropped
