I think there was one at one point, I've seen links to it from the Thunderbolt Ski Runner's club but the link just brings you to the homepage...
If you're trying to find conditions on greylock, it has snow on it. ;-) Not a lot of snow but you will find snow on the summit. I was at 2100' friday in Lenox and they had 3-4" of snow, which wasnt enough for snowshoes but greylock is higher..
