Prenatal virilization. In the prenatal period, virilization refers to closure of the perineum, thinning and wrinkling (rugation) of the scrotum, growth of the phallus, and closure of the urethral groove to the tip of the penis. In this context, masculinization is synonymous with virilization.
[QUOTE=Greatnorth;481595]Well, usually I wait till there's a good 3-4 foot of snow because you don't want your skis to touch the dirt/ground or whatever isn't snow. Snowmobiles are made to operate on snow and that's all they should do. Really 3-4 feet of snow until you go snowmobiling??? They open the trails around here when roughly 6-7 inches of snow are on the ground. Never had a problem running my sleds in 6 inches of snow or more.
How Many Snowstorms Flagstaff Gets. Most days of snowfall in Flagstaff leave at least an inch of fresh snow on the ground. For 12 days a year on average, the amount of new snow totals at three inches or more. Snowstorms of over five inches a day normally occur seven times a year. Major blizzards that dump ten inches or more in one day typically show up once or twice a year.
