You are actually looking at a fir or spruce, not a pine. The structure you are looking at is called a "witch's broom", and is actually a malformation of the tree, caused by some kind of disease or insect. This is growth of the tree in response to the pest/disease. Could be down under all of the growth is a dwarf mistletoe plant, or some gall caused by a fungal infection or insect damage.
