Over the past week, many of us have
watched watching the developing drama of the ice dams on two major
Connecticut rivers. This is a natural occurrence that doesn’t
occur very often. It is heartening that people have been paying
attention to Mother Nature and respecting her power.
Anyone who hikes in our area is also
witnessing the powerful effects of our Mother, whether they recognize
it or not. As the glaciers made their way over our landscape, tens
of thousands of years ago, those huge masses of ice scoured the land.
As they moved south, they gouged out the valleys and moved around
unmovable large areas of granite bedrock to create the ridges we are
so familiar with. Everywhere we walk, we are confronted with exposed
bedrock and interesting outcrops and rock ridges. Some are certainly
more impressive than others.
As those same glaciers moved through
the landscape they picked up boulders, some as big as houses, as well
as tons of smaller ones, all sizes, and moved them along. When the
ice began melting and the glaciers retreated, the rocks then dropped
out of the ice masses and remain dotting the landscape, in often
precarious positions. Many of Avalonia’s preserves give testament
to the process, and our trails offer close looks at glacially carved
landscapes, solid ridges, sandy streambeds in low valleys between the
ridges, kettle holes, erratics, and jumbled moraines.

Examine ice
But take some time to investigate
the gentler side of ice, the beauty of its varied shapes and
configurations. Hike along a woodland stream at this time of year
and you may see ice coated rocks and nearly frozen waters falls
spilling over them, some seemingly stopped in time.
Shallow, frozen wetlands often
become the springtime’s vernal pools. They are not deep, with
leaves lining the bottom, and a myriad of life forms hibernating or
inactive in the mud and organic debris. When the ice is clear,
notice bubbles and swirls created by the freezing water and air
trapped within. It is easy to be mesmerized by the designs in ice:
some sharp and jagged, some soft and rounded. I have had the
amazing luck to once see an Eastern red-spotted newt swimming just
under the clear ice of a frozen vernal pool. Life goes on. Pretty
amazing.
In the rocky
woodland it is also beautiful to see the icicles form where water
runs off the rock ridges and when hanging over the evergreen
woodland ferns on the rock face, they seem to create a mismatched
piece of winter art.
A drive along our coastal preserves
allows you to stop and overlook frozen marsh land as well as the
frozen coves. Because these waters are tidal, the ice rises and
falls with the water, often creating some interesting and explosive
looking eruptions around the partly submerged rocks.
Ice had the power to shape the land,
and the results influence our lives every day. Yet the seasonal ice,
which seems gentler, can still cause ice jams and floods. The most
fleeting ice is beautiful . It has its purpose in natural cycles,
yet beyond the purpose, it offers us another reason to get out and
enjoy the seasons in nature. Pure beauty.
