Winter micro climates are very common in Colorado. A Typical winter micro climate on golf courses are Northern exposures these areas hold the snow most of the winter. And the complete opposite happens on the southern exposures which are dry and greening up. So we have some areas of the course that are greening up while others are still frozen and under snow.
These two micro climates usually are not to far apart most times on the same hole or just yards from each other.
