These are the beehives I removed from within a wall at my house today. Each hive (or honeycomb) was about 3" x 5" and there were four of them. Fortunately I only have to repair a small hole in the wall.
We had a chance to get up close and personal with the pipeline. It is 800 miles long and runs from Prudhoe Bay to Valdez. About 450 miles is above ground because the oil is more than 100 degress (F) and they didn't want it melting the permafrost layer.
