David, I can't speak much as a snowshoer, but as a cross country skier. On a normal year, the April time frame gives us what we call "corn snow season." There is a lot of melt-freeze transition going on, and that develops corn snow that is good for ski touring. This year in California, that season is late by a month. Once it gets too hot, the snow will shift into what we call "soft ice cream snow." You will be tempted to kick off the snowshoes and skis and walk, but you will be postholing a lot. Believe me, when you have to walk a few miles and you are sinking in crotch-deep with every step, you will find a better way. One problem with soft ice cream snow is that you don't want to try to build snow caves and igloos with it. Staying dry is purely a matter of wearing the right layers.
