At the end of the regional sections, I list selected Ski Central or RSN month-to-date snow totals which were posted during the season. These can have missing data or double counting, but were the best contemporary estimates. The blue tables are "official numbers" compiled by ski patrols or avalanche forecasters, which I use to update my data. Comprehensive snow statistics are finally available and shown in the 1999-2000 Ski Season Summary.

California: The high volatility of Sierra snowfall was evident in 1999-2000. November was below average, and with no natural snow between December 10 and January 10 the Sierra had its worst holiday season in 10 years. From January 10 to March 10, snowfall was over 200% of normal and ski conditions were excellent. Then came another month of no natural snow and premature spring conditions. 2-3 feet of mid-April snow ensured an average late spring season. Southern California and Arizona were totally dry until mid-February with the only skiing being on snowmaking. SoCal had about a month of full operation but then lost its natural snow runs by early April. Arizona had 7 feet of snow in March and thus a stronger finish. See Current California Ski Conditions for more details on Southern California and Mammoth.
Ski Central December Snow: Squaw 29, Sugar Bowl 31, Northstar 23.
RSN January Snow: Squaw 100, Sugar Bowl 111, Heavenly 103, Northstar 102.
RSN February Snow: Squaw 110, Sugar Bowl 186, Heavenly 92, Northstar 117.
RSN March Snow: Squaw 33, Sugar Bowl 39, Heavenly 31, Northstar 28.

Pacific Northwest: These areas received the most snow in early December, and after a dry holiday, major new snow in the first half of January. Snowfall was then below average through February, but well above average in March and April. La Nina was kind to this NW skiers again, but only in Alaska did the snow totals come close to the 1998-99 records.
Ski Central December Snow: Alyeska 53, Whistler 66.5, Baker 144, Stevens 105, Crystal 66, Hood Meadows 79.
Ski Central / RSN January Snow: Whistler 65, Baker 151, Stevens 106, Crystal 82, Hood Meadows 106, Mt. Bachelor 105.
Ski Central / RSN February Snow: Whistler 24, Baker 92, Stevens 52, Crystal 68, Hood Meadows 60, Mt. Bachelor 70.
Ski Central/RSN March Snow: Alyeska 162, Whistler 47, Baker 106, Stevens 70, Crystal 56, Hood Meadows 43, Mt. Bachelor 56.

Canadian Rockies and Interior B.C.: Lake Louise and Sunshine were the only western areas with a strong November. December, January and March also had above average snow in the Banff and Okanagan regions. As in 1998-99 the normally snowier Kootenay region was closer to average.
Ski Central December Snow: Silver Star 29.5, Red Mt. 31.5, Fernie 60 since Dec. 9.
RSN January Snow: Red Mt. 57, Fernie 81
RSN February Snow: Big White 32, Red Mt. 35, Fernie 60, Sunshine 43
RSN March Snow: Big White 54, Red Mt. 40, Fernie 47, Sunshine 72

U. S. Northern Rockies: This region had a strong December to make up for the slow start. Thus Big Sky opened Lone Peak at Christmas, earlier than normal. The Yellowstone / Teton region continued above average through March and then had a warm spring. Big Mountain and Schweitzer were closer to average like their Canadian neighbors.
Ski Central December Snow: Schweitzer 77, Big Mountain 64, Big Sky 75, Targhee 61.5.
RSN January Snow: Schweitzer 54, Big Mountain 76, Big Sky 85, Targhee 100.
RSN February Snow: Schweitzer 22, Big Mountain 39, Big Sky 59, Targhee 64.
RSN March Snow: Schweitzer 30, Big Mountain 60, Big Sky 68, Targhee 60.

Utah: Utah also had the dry November with recovery through December and January. Most Cottonwood Canyon terrain was open by New Year's, but Jupiter Bowl opened January 7 and Snow Basin did not open until January 20. Utah skiing was then excellent through March, but April was warm and dry.
Ski Central December Snow: Snowbird 96, Brighton 57, Brian Head 45.5, Park City 29.5, The Canyons 36.
RSN January Snow: Snowbird 74, Brighton 74, Park City 61, The Canyons 69.
RSN February Snow: Snowbird 120, Brighton 106, Park City 75, The Canyons 77.
RSN March Snow: Snowbird 72, Brighton 77, Brian Head 83, Park City 68, The Canyons 51.

Northern and Central Colorado: This region also had to recover from a dry November. Only Steamboat was in full operation for the holidays, with Vail at about 75% with some but not all of the back bowls. Other areas were about half open for the holidays and reached full operation in January. Like other Rockies regions, conditions were very good through March and then warm in April.
Ski Central December Snow: Copper 66, Keystone 63, Loveland 80.
RSN January Snow: Copper 37, Keystone 48, Loveland 50.
RSN February Snow: Copper 53, Keystone 46, Loveland 51.
RSN March Snow: Copper 52, Keystone 42, Loveland 45.

Southern and Western Colorado: This region was severely drought impacted in the early season, with less than 1 foot natural snow in November plus about half normal snow in December. At Christmas I issued a warning, as there were 3 similarly dry seasons (1977, 1981 and 1990) when much advanced terrain in the region never opened. January was average, but fortunately February storms were more substantial, allowing Snowmass' Hanging Valley and CB's North Face to open. Colorado ski conditions were then good to the early April closings of most areas.
Ski Central December Snow: Aspen 28, Crested Butte 19, Telluride 34.
RSN January Snow: Aspen 50, Crested Butte 62, Telluride 46, Taos 34.
RSN February Snow: Aspen 40, Crested Butte 69, Telluride 47, Taos 30.
RSN March Snow: Aspen 50, Crested Butte 48, Telluride 65, Taos 38.
Official data for Colorado will be available in June.

Taos had a tough season, with the maximum base depth only reaching 55 inches, which is marginal for its expert runs. In March these runs were opened on a rotating basis to preserve cover. Only 1977 and 1981 of the past 30 seasons had less snow at Taos than this season.

Northeast: New England had only about half its normal November / December snowfall, but most of the usual snowmaking leaders were over half open for the holidays. Unfortunately, a severe thaw and some rain degraded conditions after New Year's. The East had excellent skiing with high snowfall from late January through most of February. The last week of February saw a thaw and partial meltdown, so some areas were down to 50-60% operation. Most runs reopened on new snow in early March, but ongoing warm weather reduced most areas to 50-60% again by the end of March. Northern Vermont had a much better year than the rest of New England, with Jay Peak actually setting a new snowfall record. Incredibly by western standards, Jay's base never exceeded 6 feet, as weather regularly fluctuated between big powder dumps (including a 40-inch storm in mid-April) and massive thaws.
Ski Central/RSN December Snow: Jay 64, Sugarbush 38, Killington 36, Lake Placid 16, Snowshoe, WV 31.
RSN January Snow: Jay 109, Stratton 53, Killington 36, Sugarbush 35, Sugarloaf 48, Snowshoe, WV 54.
RSN February Snow: Jay 143, Stowe 89, Killington 57, Stratton 61, Sugarloaf 50, Snowshoe, WV 21.
RSN March Snow: Jay 37, Stowe 30, Killington 21, Stratton 31, Sugarloaf 38, Snowshoe, WV 13.
