Taking refuge in accumulated snowfall

Within the last few weeks, the greater Boston area has received a record-breaking amount of snowfall from a series of storms. As part of a larger ongoing project, I've been collecting pictures from the observation tower at the Great Meadows National Wildlife Refuge in Concord, MA around the seasons.  I thought this series, showing the effect as the snow continued to accumulate, was interesting to observe.  First, on 21 January before the series of storms began:

Next, on 26 January following about 8 inches of snow around the 24th:

And on 1 February, after perhaps over 30 more inches on the 26th-27th of January:

On 6 February, following about another 13 inches on the 2nd and 2 more on the 5th:

On 11 February, after about another 14 inches on the 9th:

On 18 February, a few days after still another fall of about 14 inches on the 14th-15th:

Once it starts to thaw, I expect it'll take quite a while to unwind the accumulation.  Hat tip to the NWS Boston Significant Weather Archive page for convenient access to records; I've applied some guesswork in response to some apparent notable differences appearing between values recorded among nearby towns. In any case, it's been quite a transition to observe over less than a month.
