The Friends of the Grenville (FOG) is a loose-knit fraternity that formally came into existence in 1972 but whose roots really go back to a monumental, 3000-km-long, 12-day field trip led by Hugh R. Wynne-Edwards. Since 1970, there has been an unbroken chain of annual, September-October, two-day excursions that alternate between Ontario, Quebec, and New York.  FOG is a "nonorganization" with no dues and no formal membership. A Friday-night gathering welcomes participants with an overview of the fieldtrip and a Saturday-night banquet salutes fieldtrip leaders and the participant having travelled the farthest to join the "Friends". It is the mixture of friendships developed over the years , the rocks and their beautiful enigmas, and the frank and broad discussions on their potential solutions that keep drawing FOG members back, year after year, rain or shine.
