Since early January, we have been seeing some interesting color patterns on a few tees at Sugar Creek. In late January, after a snow melt, I was asked if the patches on the 4th tee were snow mold. From a distance, they did resemble pink snow mold patches, but I did not think that was possible given the conditions we've had.
This was the first area I looked at:

It became obvious that they had to have been caused by footprints -- but how? This area gave another clue:

4th tee |
The snow in these areas melted first in the footprints. This tee is shaded, so snow lasts here longer than open areas. There must have been a time when the the snow protected the green areas from freeze injury. A look at the weather history allowed me to narrow the date of the event to January 17th and 18th.
January 2016 weather looked like this:
Turf at the course was green all of December and into January. In mid January, it was covered by snow and still green underneath. Then we had a real cold snap on the 17th and 18th and most areas turned brown. The few areas under snow remained green. I kept expecting the color difference to even out, but for a while the difference became more pronounced due to above average temperatures.

These spots are still visible, but less obvious as of this writing - February 19th. Often you can see this phenomenon where there are snow piles or drifts melting, but it is rare to see pronounced footsteps like this. It took a very specific weather pattern to cause this, so I thought it was worth memorializing.
