You've confused the 'gentle Jeffrey' with another yellow pine. The Jeffrey Pines are those with the butterscotch scented bark. They have moderately small, unprickly cones. The similar Ponderosa Pines have prickly cones. "Gentle Jeffrey, Prickly Ponderosa."
Coulter Pines have huge cones, the heaviest in the world, with very nasty spikes on them. They are unforgettable. One of those hitting you from a height of 30' would do serious damage.
All three of these pines have been hit hard by the drought and beetle infestation.
