As far as compaction in April goes, I remember vividly the 2nd storm of back to back in April 1996 in ORH...we got clobbered with about 16”. I remember the snow was heavy until mid to late morning. I measured a depth of around 14-15” at 1030am...not even 4 hours later it was about 37-38F and overcast after the snow had fully stopped for a couple hours. I measured about 7” of compact cement. I couldn’t believe how quick it had settled.
