My wife discovered this cluster of bees on the side of the large ravine that runs across our
property.  The dirt wall was vertical and the cluster was about 14 inches long from top to bottom.  
The bees are stacked one on top of another to a thickness of about three inches.

The bees were very passive with only a few of them flying around, but the ones on the outside
were moving slightly.  I thought possibly they were trying to keep a queen warm or something,
except that  it wasn't a particularly chilly day.  They were gone the next day and left no trace
that they had been there.
