My home mountain is mt. Hood so my season ends for like three weeks but lately I've been seeing quite a lot of 13/14 season edits and its making me sad because I though there was like a month left in the season still. I might be totally wrong or people are tired of winter but I just don't understand the early season edits.
If you were to take all mountains average closing time and average them out (in the United States) I would guess around beginning of April and late March. That's just an estimated guess by me though so don't take my word for it. Honestly, it's kind of hard to answer this question because here on the East Coast we almost just had another huge snow storm so it's hard to tell what will happen next.
