SAM Magazine—Denver, Colo., Sept. 9, 2026—Alterra Mountain Company plans to invest more than $350 million across its portfolio for the 2026-27 season, with projects ranging from continued terrain expansion at Deer Valley Resort to nearly $9 million in remote avalanche control systems in California, along with snowmaking upgrades, guest amenities, and workforce housing investments.

At Deer Valley, the ongoing Expanded Excellence project will add another 200 skiable acres and seven runs served by the new Hail Peak Express this winter. The additions will bring the Utah resort to 4,500 skiable acres and 32 chairlifts. New snow feature zones with rollers, berms and gentle ski-cross elements are also planned for younger and beginner skiers.

The company is also making a significant investment in avalanche mitigation at its California resorts. Palisades Tahoe is investing $3.2 million in remote avalanche control systems, including six new Gazex and Gazflex exploders, five Wyssen avalanche towers and a new CATEX cable system. Mammoth Mountain and June Mountain are investing $5.7 million in 16 remote avalanche control systems across the two resorts. Alterra said the Mammoth and June project was nearly a decade in the making and followed years of evaluation, testing, regulatory work, and collaboration with avalanche professionals and industry partners.

Snowmaking projects are also underway at several destinations. Solitude Mountain Resort, Utah, is adding fixed and mobile snow guns and making system-wide improvements in a multimillion-dollar project that follows more than $5 million in snowmaking investments last season. Deer Valley has added a new 10-million-gallon reservoir to increase snowmaking coverage.

Winter Park Resort, Colo., meanwhile, is continuing a multiyear rebuild of its snowmaking infrastructure with additional automated fan guns and mobile guns. The latest improvements are expected to double snowmaking capacity on Lower Hughes, support earlier openings, and improve water-use efficiency.

As previously reported by SAM, Tremblant, Quebec, is embarking on a CA$42.5 million investment that includes a new beginner area for 2026-27 and, for 2027-28, 62 acres of new terrain and a high-speed quad in the Versant Soleil area.

Elsewhere, Palisades Tahoe is adding two PistenBully 600 E+ hybrid snowcats to its fleet, while Mammoth is purchasing three for the coming season. At Steamboat, excavated material from construction of The Stockman hotel and residences is being used to reshape the base of Maverick’s Halfpipe, a project Alterra said will reduce the natural and machine-made snow needed to build the halfpipe by 60 percent and allow it to open earlier.

Alterra is also continuing to invest in employee housing, with renovations planned at Palisades Tahoe, Mammoth, Snowshoe, Steamboat, and Crystal Mountain; development of new employee housing at Palisades Tahoe; and the acquisition of a housing property for Sugarbush. In the past year, the company said it secured 160 new employee housing beds at Crystal Mountain and completed renovations benefiting 200 employees across four communities.

“Over the past nine years, Alterra Mountain Company has invested at a level never seen before in the mountain resort industry, because our guests deserve the best mountain experience possible,” said Alterra chairman Eric Resnick.
