The ski area opened one run - stretching from mid-mountain to the base with no beginner runs open yet.
It's something A-Basin spokesperson Adrienne Isaac says is all thanks to snow-making crews and hard-working employees.
"Our snowmaking team is one of the best in Colorado - if not the U.S.," Isaac said. "These guys and gals are pretty tireless in terms of what they are doing snowmaking."
The process of creating the snow costs hundreds of thousands of dollars, as well as months of hard work and new equipment purchases.
"We do a lot of work with snow-making," Alan Henceroth, Arapahoe Basin Chief, said. "Our crews have been going strong for a week and a half."
It's all thanks to the science of mixing high pressure air and water during freezing temperatures.
"It was incredibly cold up here. We just made a ton of snow. We've been making snow since then and we've got enough to get it open," Henceroth said.
Other resorts, like Eldora are taking their time and sticking to their original schedule.
"We always anticipate a big year. But this year it's looking like it's lining up for some southern flows early on which we always get excited about at Eldora," El Dora Resort's Rob Linde said.
El Dora can thank El Nino for that. Unfortunately El Nino was on 'el vacation' last year.
"We just want to put last year in our rear view mirror as fast as we can," Henceroth said.
Steamboat plans to open its slopes in 36 days, Telluride on November 22 and Vail on November 16. Every single resort in Colorado spent the summer grooming and fine tuning hills by spending hundreds of thousands of dollars on new snow making equipment.
"It is absolutely imperative in this business to keep up to date on snowmaking," Linde said.
