The International Larix (larch) Arboretum was dedicated October 7, 1992 as part of an International Larix Symposium on a 1.2-acre site, next to the headquarters of the Coram Experimental Forest and near the Hungry Horse Ranger Station, Hungry Horse, Montana.

Ten species of Larix from North America, Asia, and Europe, along with subspecies and hybrids were planted. This arboretum will not only provide a visual demonstration of Larix but is designed to provide opportunities for species comparisons and genetics research.
