RUMFORD – Mother Nature finally got her timing right with Sunday’s big snow.

More than one to nearly four feet of fluffy powder blanketed much of Western Maine, enabling ski areas throughout Oxford and Franklin counties to open all or nearly all trails and features for the holiday week.

At Black Mountain ski area in Rumford, lodge manager Lisa Arsenault said Wednesday that 18 of 21 trails would be ready for skiers and riders on opening day Friday.

“We’re open all the way to the top, so we’re pretty happy about that,” she said. “This is the first time in a lot of years that we’re able to do that. We got 18 to 20 inches on Sunday, and it’s snowing here right now. Hallelujah!”

Friday also marks the first time a season-pass holder will win the morning’s debut drawing to be the first skier or snowboarder on the mountain this season.

There will be two drawings, one for the novice chair and one for the summit chair. The drawings will be held at 8:45 a.m., just prior to opening.

Still to come are the tubing park, which needs more snow to build up the sides, the terrain park and a couple of alpine trails. All Nordic trails are open.

“We just need two to three days of cold weather that’s definitely not in the 30s,” to make enough snow to open all areas, Arsenault said.

At Mt. Abram Family Ski Resort in Greenwood, all but three trails were open, offering skiers and snowboarders a base depths of 10 to 50 inches, according to its Web site. The tubing park was expected to open this week.

At Lost Valley in Auburn, which got 21 inches of snow over two days after opening for the season, all but two of 13 alpine trails and the terrain park were open, according to office worker Amanda Poliquin. Usually at this time, they’ve only made enough snow to open half of the area.

Shawnee Peak in Bridgton was 85 percent open on Wednesday. It was closed Christmas Day but set to reopen on Friday with five lifts running, according to marketing manager Melissa Rock.

Titcomb Mountain in Farmington was also closed Christmas Day but will be open from 10 a.m. to 4 p.m. on Friday and through New Year’s, offering two lifts, according to its Web site.

The bigger ski resorts, which opened earlier thanks to snowmaking, have all or most trails up and ready.

Jennifer Dugas in the ticket office at Saddleback in Rangeley said all trails were open, but the terrain park needs a bit more snow.

“It’s huge to have all our trails open this time of the year,” she said. “We don’t quite have enough for our half-pipe and such, but we’re very close to it.”

Sunday’s storm dumped 24 to 30 inches on Saddleback, which opened on Dec. 13.

Sunday River Ski Resort in Newry had 95 percent of its area open, offering 115 trails as of Wednesday afternoon, according to lodging switchboard operator Sarah Mayberry.

Carrabassett Valley’s ski hill, Sugarloaf/USA, was also 95 percent open, with 123 of 130 trails open following Sunday’s 32 inches of powder, according to office worker Cindy Dunn.

“To have this much open before Christmas, it’s unusual,” she said.

Nordic ski area owners were equally thrilled with Sunday’s snow and were at 95 to 100 percent operational.

“That really was a big help. It made it nice for us,” said Anne Carter, co-owner of Carter’s Farm XC in Bethel and Oxford. “We opened Monday for the season and we did quite a bit of business. It was very nice.”

All trails were open at Sunday River Inn Cross Country Ski Center in Newry and the Rangeley Lakes Trail Center in Rangeley. The Bethel Inn Ski Touring Center has nearly all of its trails open, according to Mike Cooper.

“We have tracks all over the place,” he said. “Counting both last winter and this winter, this is the first time in the 25 years I’ve been doing this that we have nearly all of our trails open before Christmas, so I’d say it’s good.”

Snowmobilers were also rejoicing at the sudden availability of thousands of miles of trails across Maine.

According to Bob Meyers, president of the Maine Snowmobile Association, Sunday’s storm could provide a base for the entire sledding season “if people don’t go out and tear up what’s there now” before clubs can get out and groom.

The association represents about 285 snowmobile clubs which help groom Maine’s 13,500 miles of power sled trails.

“What we have out there now will keep us going all winter long,” Meyers said.
