This is a sizeable wound on this tree. The picture is helpful but from the picture it is not possible to determine if it is a physical/ environmental injury - weather related, or if there is a pest/disease element.
You could contact your local Extension Office & show them the picture and get their advice on obtaining a sample of the bark near the injury and sending it or taking it to their Diagnostic Lab.
You could also contact a certified arborist in your area to provide an in-person consultation on the tree. A list of certified arborists is available through:
The Associated Landscapers of Colorado (ALCC) www.alcc.com
or
International Society of Arboriculture (ISA)
