Found Insulated Water Bottle. Let me know if you lost one, we can meet up in greater Seattle.
The trail from the trailhead to the major split is all packed and easy to walk even without snowshoes. Most people were turning around here (which still makes a nice day). Once you split, the trail conditions change dramatically. Recent avalanches have taken out the trail on both routes. Source Lake is easier and can be accessed via the lower route too. Not much to see as the lake is mostly covered so don't worry if you don't make it all the way.
If you plan on going to snow lake, you need appropriate gear, navigation skills, and experience until someone cuts the trail or more snow falls. It's pretty vertical on the last set of switchbacks and the snow conditions weren't making the climb very easy.
