Here's a pretty cool tool from postholer.com for looking at snow depths on a topo map.
To change the date, just modify the URL in the same 8-digit format. You can go back a few weeks and see how fast it's melting or go back to any year and compare to this today.
This dataset is a low-resolution overlaid so I wouldn't rely on it for a specific location, but you can gain some good insight with it by combining it with beta from other seasons or times of year with similar coverage.
