Pinus coulteri probably has the biggest cones, 40cm long and 1.9kg max.
Pinus edulis supplies most of the edible "pine-nut" market in North America, native habitat are the 4-corners states: Utah, Colorado, Arizona and New Mexico.
All other species should be edible but tedious to collect, particularly from serotinous cones.
Today, I saw two Cabbage Whites (Pieris rapae ?), most, most unusual.
Commonly early spring butterfly that I expect to see is the Mourning Cloak (Nymphalis antiopa).
I think the common name in the UK is Camberwell Beauty, they over winter as adults.
