An interesting hike can be made from Osmore Pond to Deer Mountain but as the trail is poorly marked, one must maintain a sense of direction. From the Osmore picnic area walk south near the shore of the pond to its outlet into Osmore Brook. At this point turn left to the northeast and follow the trail which parallels a wire marking the edge of the game preserve. About three-fourths of a mile from Osmore Brook the trail meets another trail at right angles. To the left the trail follows the game preserve boundary northwestward. The trail to the right leads directly to the top of Deer Mountain where a view may be obtained on the south side of the summit. As an alternate route for returning, follow the trail along the game preserve to the northwest. Some distance beyond a shelter-lean-to the trail divides several times with the main trail leading to Blake Hill and other trails to the left leading to the Osmore Pond road. A hike along the trail on the north side of Kettle Pond to the shelter-lean-tos makes a pleasant trip along the water. Also, the trail from Owlshead Mountain to Osmore Pond is convenient for a short hike through the woods, if the trail can be found. _Quarries at East Barre_ The granite quarries at East Barre are in nearly the same type of rock as that which occurs at Groton State Forest. The quarry operations are interesting and educational and the quarries afford a good opportunity of seeing fresh, unaltered specimens of granite. Guide service is offered at some of the quarries. FOOTNOTES [1]_Granite_ is a type of igneous rock consisting of large interlocking grains of light-colored minerals. Rocks are classified as being either igneous, sedimentary, or metamorphic. _Igneous_ rocks form by the solidification of molten material; _sedimentary_ rocks form by the accumulation of sediments derived from older rocks; and _metamorphic_ rocks form by the recrystallization of older rocks under conditions of high temperatures and pressures. [2]_Dip_ is the inclination of a surface as, for example, a joint surface described above. [3]_Schist_ is the name given to rocks in which the minerals have a parallel alignment due to reorganization of the rock constituents during a condition of high temperature and pressure. The platy minerals, like mica, form at right angles to the pressure so that the resulting rock may have a “bedded” appearance.
