Missing data determined as follows:
(a) Date - Depth of snow and relative depth compared to other snowpit leads to conclusion this is more representative of a mid-season snowpack
(b) Time- Warmer air temperature and impact deeper in the snowpack indicates later in the day observation
(c) Aspect - Relative to first pit, location would be on aspect more likely to hold snow and experience temperature gradient exhibited later in the day.
(d) Zone - ATL due to proximity to I70 in CO and temperature gradient evidence
