| Notes: | |||||||
| Ice on fresh ponds; leads are still open | |||||||
| fresh small scale ridging - evidence of recent wind | |||||||
| Lots of loose floes in leads - more evidence of recent wind | |||||||
| new snow evident in ridged areas- drift - otherwise snow on ice surface not very distinct | |||||||
| Leads had wind streaked patterns- corn rows | |||||||
