April 4, 2023 - Snow Lingers in the Adirondack and Green Mountains

Snow

Snow lingered in high elevations of New York and Vermont in early spring, 2023, calling to mind a line penned by New York native Lorraine Amada. “Winter has overstayed her welcome again, the guest who won’t leave after the nightcap,” she wrote in her poem, Lingering Winter.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a true-color image centered on snow-topped Adirondacks on April 2. While much of the landscape is snow-free and the lakes and rivers are ice-free, snow still clings to the Adirondack Mountains of New York, the Green Mountains of Vermont, and on the far northern landscape of the province of Quebec, Canada.

The Adirondack Mountains are made of ancient rocks, more than a billion years old, that uplifted into a dome about five million years ago. When viewed from space, they appear clustered in a circle rather than stretched out like more typical mountain chain. In this image, the snow atop the high country highlights the near-circular shape. To the east, the Green Mountains stretch from northeast to southwest, forming a broad chain that extends southward. As part of the ancient Appalachian Mountains, which formed more than 400 million years ago, Vermont’s Green Mountains are much older than the Adirondack Mountains.

On March 13-15, a powerful nor’easter dumped heavy snow in the mountains of New York, Vermont, Massachusetts, and New Hampshire. Some areas in Vermont received more than 36 inches (76.2 cm) of fresh snow, while a few spots in the Adirondacks reported 40 inches (101.6 cm) of snowfall in 48 hours. The deep snow will melt as spring progresses, but appears to be in no particular hurry to do so.
