Saturday January 23 we skied at Greenwood Park. We were headed further north, looking for snow but there was a surprising amount as we approached Greenwood, so opted to give it a try.
The trails had 3-4" of light new snow on top of whatever was left from previous snows. The park office was not open, hence no trail fee or rental availability, and they have not packed the trails and probably don't have enough snow to do so.
However, we were able to ski everything we tried (Woodland, Lake, Creek, and Outer trails). Some of the downhills are tricky because there's enough snow to hide ruts and frozen footprints, but not enough snow to render them irrelevant. If you go, it might be best not to use your shiny new skis, but there is adequate cover most everywhere.
