In 1976 Mrs. Stephen Gray generously gave this land to SVT as a sanctuary for birds and wildlife. Because the land is almost entirely surrounded by residential development, its preservation as open space is particularly valuable.
- Along with the adjacent conservation lands, Gray Reservation provides an outdoor museum of geologic features carved by the last glacier. Most striking is the 40-foot-high ice-contact face that rises just south of Hop Brook. The top of the face is pitted by kettle-holes that were formed when sand and gravel settled around chunks of ice left behind by the glacier. Eskers also wind through the property, and the glacier also left behind erratics, a drumlin, and a kame terrace.
- A ramble through the properties on the map will take you through white pine and mixed oak woods, past flood-plain marshes and red maple swamp, across streams, and along the shores of man-made ponds. Wildflowers are common in late spring and early summer.
- The Gray family created a pond by damming the stream that flows through the property to Hop Brook, a major tributary of the Sudbury River. Only the fireplace (by the bridge near point D on the map) remains of the cabin the Grays built near the dam, once the site of skating parties and dances. Stone walls enclose their former garden on the south side of Hudson Road.
