SKIING : Western Weather Agreeable

Skiing is breaking out all over the West this week as a result of last weekend’s storm and the cold temperatures in its wake.

In the Southland, all three major Big Bear Lake ski areas--Bear Mountain, Snow Summit and Snow Valley--opened for the season Wednesday, and they will be joined today by Mountain High, near Wrightwood.

Bear Mountain, like its neighbors, has been making snow almost continually since Sunday and is operating two chairlifts, with skiing on runs up to a mile long from its 8,400-foot summit.

Snow Summit is running Chair No. 10, serving Miracle Mile and most of Summit Run, and No. 8 for beginners.

Snow Valley is offering beginning and intermediate skiing on Chairs 6 and 13.

At Mountain High, the top of the West terrain reportedly has up to two feet of snow.

The High Sierra is blanketed with two to four feet of natural snow, augmented here and there by men and machines.

Mammoth Mountain had 12 lifts churning away Wednesday and will add at least Chairs 7 and 16 for access when it opens Warming Hut II Friday. June Mountain is going with five lifts.

Other Sierra resorts already under way include Squaw Valley, Alpine Meadows, Heavenly Valley, Kirkwood, Mt. Reba-Bear Valley, Sierra Ski Ranch and Boreal.

Scheduled openings include:

--Today-Dodge Ridge.

--Friday-Sugar Bowl, North-star, Ski Incline and Mt. Rose (with the Slide Mountain side added on Saturday).

--Saturday-Sierra Summit, Homewood and Tahoe Donner.

Alpine Meadows, just north of Lake Tahoe, will play host to the first event on the U.S. Pro Tour this weekend, with three-time World Cup champion Phil Mahre again expected to be the man to beat.

Phil’s twin brother, Steve, also says he hopes to compete this season but is sidelined with a tender knee.

The giant slalom will be held Saturday, the slalom Sunday--both at 11 a.m. A celebrity pro-am, with a field that includes Britt Eklund, Dan Fogelberg and Steve Kanaly is set for Saturday afternoon.

Elsewhere around the West, Utah seems to be blessed with the most snow. Snowbird, Alta and Brighton each report more than five feet on their slopes, and Park City, where the World Cup men’s slalom was canceled because of Sunday’s storm, has nearly three feet.

In Colorado, where depths are more like those in California, operational resorts include Aspen-Snowmass, Breckenridge, Copper Mountain, Keystone, Crested Butte, Vail-Beaver Creek, Steamboat, Telluride and Winter Park. Aspen Highlands will open Friday.

Oregon’s Mt. Bachelor got going Saturday and reports nearly three feet on its runs, which are being served by six lifts.

Other planned openings:

--Sun Valley, Ida., which will run its Greyhawk chairlift for skiing on Lower and Middle Warm Springs, starting Friday.

--Jackson Hole, Wyo., which already has a base ranging up to more than four feet, on Dec. 8.

--Taos Ski Valley, N.M., which has a new quad chair and new lodge completed, on Dec. 15.
