All, What would be the easiest way to reclassify a slough of single band cloudmasks I have downloaded from the USGS High Level Data Product download? Pixels are currently assigned as follows: 0 clear 1 water 2 shadow 3 snow 4 cloud I'd like to designate "Clear" as "1" and everything else as "0". Any thoughts? I was considering Band Math but couldn't figure it out. Thanks in advance for any help.

You could use a logical statement in Band Math that will basically make a binary mask: b1 eq 0 which will return 'true' for values of 0 and 'false' for everything else.
