October 20 Beautiful new viewpoint! by David Mix Barrington

I hiked the M&M (white) trail north from the end of Alexander Hill Rd in Northfield, and found a clearing with a picnic table (presumably made by state forest people) on the east side of Stratton Mountain. There was a beautiful panoramic view including Monadnock and Mt. Grace. Is there documentation anywhere for the many marked hiking trails? (I saw blue, purple, and yellow along with the white.)
