Monument Mountain stands over the north end of Great Barrington, and by mid-October the whole ridge runs rust and gold down toward Beartown. Southern Berkshire Tree & Land keeps lawns and grounds through this end of the county — mowing, edging, trimming, mulching beds, and hauling off the leaves that arrive here by the truckload. Properties on the wooded edge get shade half the day and leaf fall for six weeks straight, which changes everything about how the turf is handled. A lawn raked clean and cut one last time before November looks like a house that is ready for the cold. Then the ridge goes bare, and the valley waits.
