Deer Valley will embark on one of the largest terrain expansions in US ski history over the next decade in partnership with Extell Development Company. As part of the Expanded Excellence vision, Alterra Mountain Company will develop ski operations in the area previously known as Mayflower with nine new lifts opening in the 2025-26 season and seven more to follow. All told, Deer Valley will more than double in size to 5,726 acres with 37 lifts.

The majority of the new terrain will launch in late 2025 with 110 new runs and a 2,900 foot vertical drop. Extell will continue to develop the base portal it has been building along US-40, which guests can reach seamlessly from Salt Lake City. Alterra will manage the mountain experience under a long term operating agreement and skiers will enjoy the same elevated service and amenities they have since 1981, albeit on a dramatically larger footprint. Deer Valley expects to hire 2,000 employees to support this expansion along with additional parking and workforce housing.

New York-based Extell embarked on the Mayflower project years ago with a purchase of 40 acres and acquired more than 20 parcels since. Company founder and President Gary Barnett noted negotiations with Alterra were intense at times and a deal was only finalized this week. With the two companies in agreement, skiers will enjoy an improved ski experience under the Deer Valley brand rather than having to choose between two adjacent, competing ski resorts.

Construction has already begun on the base portal and new terrain. The flagship of the expanded lift system will be a 10 passenger gondola spanning nearly 10,000 linear feet from the new base portal to Park Peak with a mid angle station. A dozen detachable chairlifts and three fixed grip lifts will also service the expansion at full buildout. A majority will be quads in Deer Valley tradition with manufacturer(s) to be determined.

“Deer Valley Resort is committed to building upon our legacy as one of the world’s most exceptional ski areas while staying true to our founding principles created over four-decades ago,” said Todd Bennett, President and COO of Deer Valley Resort. “This expansion will facilitate even better access to the resort for our guests, while offering a substantial increase in world-class amenities consistent with the resort’s original vision.”
