Skiing could take place at the CairnGorm Mountain resort at midsummer for the first time in living memory.
The site's Colin Kirkwood said skiing would be available this weekend for the first time since 1992 but skiing could continue until after 24 June.
CairnGorm Mountain's season will continue over weekends while there is enough snow.
The Ptarmigan Bowl and the resort's sledging area still have deep coverings of snow.
CairnGorm, along with ski centres at the Lecht, Nevis Range, Glencoe and Glenshee, benefited from heavy snow and freezing conditions over the winter.
Mr Kirkwood said: "If there is skiing at midsummer then that would be the first here in living memory."
The season ends when ski tows and the ski patrol no longer operate.
Figures recently released by Ski Scotland showed the country has had its best season in 14 years.
Since late November, Scotland's five mountain resorts have attracted 373,782 customers.
The ski season is estimated to have attracted £37.5m into the local economy.
