Two nature-lovers celebrate their nuptials at a mountaintop ceremony

The couple's rustic September ceremony and reception held atop Aspen Mountain featured an oxygen bar so guests could endure the extreme elevation in the ski lodge–like setting.

The groom’s parents brought in an oxygen bar from Oasis Oxygen Bars to prevent guests from experiencing altitude sickness. The Sundeck, a room operated by The Little Nell where the reception took place, is over 11,000 feet above sea level. Guests lined up to try flavors like Sex on the Beach and Vanilla Bean.
