I was intrigued that the radar from the Wilmington site showed the
concentration appearing along the area of  Hoover Dam at about 8 am. This
lasted only briefly until it moved north and spread out. After some
reflection, it occurred to me that it must have been due to geese and/or
other waterfowl which had been resting overnight on the lake and taking
off for daytime feeding grounds.
