I apologize for what must be a common question, but I lack the vocabulary to do an intelligent search. I am attempting to use the information in one raster (slope, computed with spatial analyst) to mask the visibility of another raster (aspect, also computed with S.A.). Essentially, I would like to display the aspect if and only if the slope in the corresponding location is between 20 and 60 degrees (highlighting avalanche danger). I have access to all the toolboxes. Any help or even general direction would be most appreciated. Thank you.
