What species cone is from?

One of the sugar pines I think

I search the internet about that sugar pine, it just can't be that one.
It is a very big cone with a big spines. It's about 15 cm long and 13 cm width.
I found it in one park in my town, but I forgot to look at the needles.

The sugar pines can have cones 25 - 35 cm in length. I doubt it is Pinus coulteri unless it was an import. But my tree knowledge isn't great!

We always call Pinus coulteri the Big Cone Pine so posibly it is that. There are so many Pines that witthouit seeing the tree itself we can only guess.

Thank you. about the production from seed, I collect all seeds from the cone and put them ion the freeze and keep them until next autumn. after that, sowing them.
Any other suggestions on stratification of seeds?
