This is a cone from a Coulter Pine or Big-cone Pine (Pinus coulteri). It is native to the coastal mountains of southern California. Coulter Pines produce the largest cones of any pine tree species. These spiny cones are 20-40 cm (8-16 in) long, and weigh 2-5 kg (4-10 lbs) when fresh. People are actually advised to wear hardhats when working in Coulter Pine groves, and the large size of the cones has earned them the nickname “widowmakers” among locals.

I brought it back from Mt. Wilson whilst I was working at the observatory near Los Angeles. I probably broke all sorts of quarantine laws in the process, but I wanted one to keep.
