FRISCO — It has been a weekend of low temperatures, and Arapahoe Basin Ski Area and Keystone Resort are taking advantage to stay in the race to open.

A-Basin called Friday their “best night yet” in a Twitter post. According to A-Basin Chief Operating Officer Alan Henceroth’s blog, the wet-bulb temperature was down to 20 degrees. 

Glossary Of Snowmaking Terms

Wet-bulb temperature: The wet-bulb temperature is the temperature a parcel of air would have if it were cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat being supplied by the parcel.”

Whales: The snow piled up in large mounds.

Snow guns: A machine that makes artificial snow and blows it onto ski slopes.

Race to open: The competition among Colorado ski areas to be the first to open for ski season.

“I think we went beyond just test mode and really made some snow. While I can’t call the snow piles or whales yet, we have moved beyond just white spots on the ground,” Henceroth wrote. 

Henceroth pointed out that A-Basin has a full reservoir and good streamflow, meaning water supply isn’t limiting their snowmaking. Snow guns ran until noon Saturday, according to Henceroth. Sunday morning, A-Basin reported another great night of snowmaking.

While temperatures are forecast to be a bit higher during the next few days, real snow is expected to blanket the basin Thursday, and temperatures in the negatives are forecast for the days following that.

Over at nearby Keystone, the resort is hyping up its Keystone Kickoff

While Keystone hasn’t announced an official opening day date, the resort has invested in new, high efficiency snowmaking equipment this year, all in an effort to open earlier. The resort also posted pictures on social media channels of continued snowmaking over the weekend. 

Keystone also has snow on Thursday and subsequent negative temperatures in their forecast, keeping the two ski areas neck-and-neck in the race to open.
