Mt. Elbert is the highest mountain in Colorado.  It rises almost directly above Leadville from the west.  It has several nice snow routes.  The east face, gets slushy and avalanche prone quickly in the spring but it does make an excellent steep descent when ridden at the right time.  The west couloir also makes a classic descent.
Due to ease of access and reputation as the highest peak in Colorado it was probably ridden in the early days of snowboarding.  Any dates you can supply would be extremely helpful.
