I pulled the left cone off a larch tree in Vermont, thinking it was most likely an American Larch. Now I'm not so sure...The right cone is a Japanese larch for comparison.

I think it is likely a Larix decidua,(European Larch). The cone seems too long and has too many scales to be Larix laricina, the Tamarack Larch (it seems to have a lot of names and I am assuming this is the species you are mentioning.
Per my ancient copy of "Fruit Key & Twig Key" by Harlow, L laricina cones are about 5/8" long, and L. decidua 1" to 1 1/4" long.
This is fun, but most folks would think we are odd.

MLM, only non-gardeners would think you odd. In the gardening realm...you rock!

Very cool. I'm glad to add a new species to my brain inventory!
