Pine (Pinus). Show habit, bark and mature cones in order to facilitate the most certain species level identification.
Thanks very much. Will bring short lens next time I go there. Fortunately, trees have no feet and stay put.
Tree 1 - Mountain Pine Pinus mugo (note cones without prickles on the scales) Tree 2 - Lodgepole Pine Pinus contorta (cones with long prickles on the scales)
