The roads colored red have been added because even though they exist, do not appear on today's maps and on the 1830 map they are not named. So I took the liberty of unofficially naming them simply for the sake of identifying them for directions. Though there are five different ways to get to the Monument only two are advised for safety. The others, one of which is shorter by far, require negotiating Beaver dams. Following are directions of the shorter of the two safe routes:
Enter Millyard Road via Rt. 68 (S. Royalston Rd.) going all the way to the end. You can either begin your hike here, or if you've a vehicle with modest ground-clearance, you can drive across the steel bridge to 'Stockwell Intersection'. (The steel girder bridge is in excellent condition with steel mesh paneling resting on five 15" steel I beams on solid cement foundations. It once bore the weight of a loaded gravel truck and will easily accommodate today's vans or pickup trucks.) Stockwell Intersection is a bit tricky to find on your first visit. After going over the bridge, continue past the Gravel Pit, an open area on your right, up a slight hill looking for the opening in the wall on your right. (At your left you'll see an area open enough for a vehicle to park.) There are a few trees right in the middle of the beginning of Gale Hill Road but you should see a trail created by ATV's. You may get a better sense of location by viewing the 1830's Map. Once through the trees the road becomes clear. Continue heading south up Gale Hill Rd. to the top of the hill. (If interested, look for Jonathan Gale's barn foundation at the top of the hill on your left, and his house foundation on your right.) Turn left (E) down Bartlett Rd. 'til you come to the stone wall on the left (N) side of the road. The wall is in distinctively good condition and travels due North as far as the eye can see. Continue approx. 200' past the wall, then turn left (N) and walk in 485' keeping to your right towards the edge of the dropoff. Watch diligently, for in spite of it's five foot size it blends in, hiding itself rather remarkably amongst the surrounding trees.
