Assuming an ERUV can someone shovel snow on Shabbos?
Yes, it may be shoveled.
It is questionable if snow is muktzeh, according to many opinions it is not, see Beis Yosef at end of O:C 310 with regards to rain. Even according to the opinions that it is muktzeh, this would be indirect movement [through the shovel] which would be permitted. In addition, moving muktzeh which presents a danger to people walking by, is also permitted.
