The tony Utah ski resort accelerated work on a long-awaited expansion along its eastern slopes
October 20, 2025
As soon as the last skier left Utah’s Deer Valley resort at the end of the season, construction crews moved in to begin work on what resort officials call the largest current expansion of a ski resort in North America. Under a plan marketed by the resort as Expanded Excellence, work that began in 2024 moved into high-gear in the summer as Deer Valley executes plans that will more than double its skiable acreage to 5,726 from the current 2,026 over the next two years.
Deer Valley’s parent company, Colorado-based Alterra, has said the project is the largest they have ever undertaken in one season.
The expansion is taking place east of the existing resort in an area known locally as the Mayflower property, named for the silver mine that once operated there. The expansion has been part of the long-term vision for the resort, says Garrett Lang, senior director of mountain operations for Deer Valley. That vision only became a reality when the resort was purchased by Alterra in 2017. Alterra signed an agreement with New York-based Extell Development to develop and operate new facilities at the resort. Extell holds the long-term leases for the land and is developing the on-mountain facilities with Deer Valley. Daily operations at various facilities will be split between Deer Valley and Extell.
As part of Alterra, Deer Valley joins nearly a dozen other resorts in North America owned by the company, which offers access to all of its properties through its IKON pass.
