How deep is the snow on Jill's bucket?

The snow on Jill's bucket is 3.74 inches deep.

Thus completes the experiment! The original snow-measuring mission was such a success that DASA (the Delaware Aeronautics and Snow Administration) greenlighted a 24-hour "extended mission" to measure melting, sublimation and wind loss.
