Vintage vehicle still a hard-working winter warrior

A fully restored Allis-Chalmers M7 (no. 195)
Clell Ballard’s fully restored Allis-Chalmers M7 (no. 195). Unique among all M7s, this one’s original color was battleship gray. It is shown here traversing a valley floor (estimated 5,000 feet elevation) with Soldier Mountain (10,000 feet elevation) in the background.
