Story

From 1999 until 2009, this Alderleaf Mountain Mahogany stood as the unchallenged National Big Tree Champion, which named it the largest of its species in the United States. In 2009, another considerably large Alderleaf Mountain Mahogany was discovered in the same area as the exisiting champion and was named as Co-Champion. Today, both Co-Champions still stand, nestled in Neffs Canyon on opposite ends of a mine tailing pile from each other.

These trees are located in overlapping habitat for two mountain mahogany species: alderleaff (Cerocarpus montanus) and curlleaf (Cerocarpus ledifolius). There is some debate that these co-champion alderleaf specimens are actually a hybrid between the two species. Though the physical appearance of the tree clearly identifies it as an alderleaf mountain mahogany, however on a re-measurement visit in March of 2013, the trees were discovered to be semi-evergreen. This is a characteristic of the genetically larger curlleaf mountain mahogany; alderleaf mountain mahogany typically loose all their leaves in the winter.
