( NATHAN BILOW )

T his season marks milestones for six Colorado ski resorts. Copper, Steamboat, Vail, Eldora, Loveland and Telluride all celebrate milestone anniversaries this year, and are hosting special events and deals for skiers and riders.

Here's our list. Now go out and get your shred on.

Copper Mountain

Anniversary: 40th

First season: 1972-1973

Copper sits on land that was first developed in the mid-1800s by miners seeking precious metals. Copper was, in fact, discovered in Summit County, hence the resort's metallic namesake.

The resort's founder Chuck Lewis purchased 280 acres at the mountain's base in 1971, and construction of trails began that summer. The mountain has since grown to 2,433 acres.

Copper had its birthday bash in December, but has events going on all season that coincide with the milestone year.

Steamboat

Anniversary: 50th

Opening date: January 12, 1963

To celebrate its golden anniversary, Steamboat has decorated a No. 50 Golden Gondola Cabin, which was auctioned off to benefit the Steamboat Springs Winter Sports Club Scholarship Fund on opening day.

Also catch several 50th anniversary parades and fireworks shows on Dec. 31, Jan. 12, Feb. 14 and Mar. 17. The official anniversary celebration will take place Jan. 11-21 with parties, a birthday cake, free music and more.

For the foodies out there, Steamboat has concocted a special 50th anniversary drink -- the Golden Antler -- which you can get as a shot, on the rocks or as a martini. It's a mix of honey bourbon, peach schnapps, orange juice, ginger ale and Anheuser-Busch's Steamboat Golden Ale.

Vail Mountain

Anniversary: 50th

Opening Day: December 15, 1962

Vail opened 50 years ago during the middle of a mild weather with little snow. Tickets that year were $5 a pop for one gondola, two chairs, eight ski instructors and nine runs.

Vail celebrated its birthday officially on Dec. 15, but the festivities won't stop until summer 2013. The resort has a new gondola --and an anniversary film, which is being shown throughout the winter. The Burton U.S. Open moves to Vail this year (Feb. 25-Mar. 2) after spending 30 years on the East Coast.

Eldora

Anniversary: Eldora

First season: 1962-1963

"Lake Eldora" opened for its first day of skiing in 1962 with two T-bar lifts during a lackluster winter. During the early years, Eldora opened for about 30 days multiple seasons in a row because of marginal conditions.

During the 1980s, ticket prices at Eldora ranged from $13 on weekdays to $15 on weekends. To celebrate, Eldora will host a scavenger hunt Feb, 23 and Retro Day on Mar. 16.

Loveland

Loveland turns the big 75 this year, and has grown a lot since the 1930s, when a Model T engine powered a tow up the mountain.

Now, the resort has 1,800 skiable acres, 93 trails and 10 lifts with around 422 inches of snow each year.

Loveland celebrates its milestone year with a free anniversary party on Saturday, Jan. 12 with live music, food, drink and prizes. Celebrate your special day during the 22nd annual Mountaintop Matrimony ceremony at Loveland on Valentine's Day.

Telluride

Anniversary: 40th

First season: 1972-1973

Telluride officially opened in 1972 with five lifts and a day lodge. The town of Telluride wasn't linked to the ski area until 1975, when the Coonskin lift was installed.

The ski area installed its first snowmaking system in the early 1980s, though now the area averages 300 inches of snow each year and boasts more than 300 days of sunshine each year. Now, the resort has 18 lifts, 125 trails and more than 2,000 skiable acres.
