The road to the Frozen Four has some new travelers.

When the field of 16 teams that will compete for the 2011 NCAA Championship was announced on Sunday morning, the traditional powers were well represented with reigning NCAA champion Boston College and perennial tournament opponent North Dakota claiming top seeds in their regions. Schools like Denver, Colorado College, New Hampshire and Michigan also are in the running. Programs that have been steadily growing in recent years -- like Miami University, Notre Dame, Yale and Nebraska-Omaha -- are in the mix as well, with the RedHawks and Bulldogs among the top seeds.

However, four of the teams in this year’s tournament aren’t quite as familiar. They are making their first NCAA appearances in at least 15 years and in one case, the first bid in the program’s history at the Division I level.

That program is Union, which will face Minnesota Duluth on Friday afternoon at the Arena at HarborYard in Bridgeport, Conn., the first of two semifinals in the East Regional. The Dutchmen reclassified their hockey program from Division III to Division I in 1991. Nate Leaman’s Dutchmen won this season’s Cleary Cup as regular-season champions of ECAC Hockey. Friday’s game against the Bulldogs will be Union’s first game in an NCAA tournament since 1989.

Union’s travel partner and rival in the Capital District of upstate New York, Rensselaer is also making a long-awaited tournament appearance, facing North Dakota on Saturday in the first of two Midwest Regional semifinals at the Resch Center in Green Bay, Wis. The Engineers haven’t competed in the NCAA tournament since 1995, in the first season for former head coach Dan Fridgen. Seth Appert, however, has brought RPI back to the tournament in his fifth season as head coach.

RPI will have company in Green Bay, as Western Michigan will also be making its first appearance since the mid-1990s when it faces Denver in the other semifinal. The Broncos won just eight games last season, but first-year head coach Jeff Blashill has turned the WMU program around, bringing the Broncos to the CCHA title game before coming up short against Miami (Ohio).

Finally, Merrimack returns to the tournament for the first time in 23 years, and the first time as a Hockey East school, when the Warriors face Notre Dame on Saturday in a Northeast Regional semifinal. Merrimack won the Division II Championship in 1978 and would love to add a Division I title to the trophy case after coming up short against Boston College in the Hockey East championship game.

The Midwest Regional will also feature two Hobey finalists in one game, as Rensselaer senior forward Chase Polacek will lead the Engineers against national goal-scoring leader Matt Frattin and North Dakota. Boston College’s Cam Atkinson will try to lead the Eagles back to the Frozen Four with a win in the West Regional, while Minnesota Duluth’s Jack Connelly will look to get the Bulldogs back to the Frozen Four for the first time since 2004 with a win in the East Regional.
