    I am asking.

    It is in Reno NV.

    Based on 2 needles per branch and 5 inches long, I now think it is Pinus contorta.

    5 inches long is unusual for contorta. 1.5″ to 2.5 inches is more typical in BC, Alberta, Saskatcewan, Manitoba.

    makes no mention of any subspecies with needles this long.

    I’m not familiar with the pines of the American southwest in detail. I’m familiar with lodgepole, as it’s a staple native tree here. Pinyon is certainly possible. The mountains in the southwest tend to form fairly isolated regions — speciation has run rampant, and there are some 12 pines that appear to be closely related.
