I noticed last week that there was a fine layer of white dust all over north campus. The dust is due to some work being done on the Dean Rusk building. This is happening at night during the week and during the day on weekends. The workers are basically grinding away at the mortar between the bricks on the building. I came in on Saturday and heard what sounded like 3 or 4 grinders whirring away. The weekend rains seem to have helped settle the dust a little, but I think the grinding continues. That building isn't that old. I wonder whats wrong with the mortar?
Anyway, if you notice the dust, thats what it is. Its everywhere.
