Weber State, down by 12 points in the second half, watched Anderson's shot bounce harmlessly away, allowing the Wildcats to escape with a 76-74 victory and a date with Montana for the Big Sky Championship in Dahlberg Arena.
Tipoff is scheduled for 7 p.m. Saturday on ESPNU.
"It was like slugging rats out there," WSU coach Randy Rahe said.
Certainly, third-seeded North Dakota (16-16) plagued Weber State. For a time, it was converting shots at a 60 percent clip. Every strange bounce went its way.
Even as Berry continued to attack the basket en route to a 25-point night, WSU center Kyle Tresnak became saddled with foul trouble as UND shredded the Wildcats' vaunted defense.
And when North Dakota's Troy Huff slammed home a Jamal Webb half-court lob to take a 52-40 lead three minutes into the second half, the upset appeared all but complete.
That's when senior experience and freshman enthusiasm took over.
First, WSU's senior guard Scott Bamforth gathered his teammates together.
"That was a time where we needed someone to get everybody together and make a push," said Bamforth, Rahe nodding in agreement. "If we didn't do it then, we'd never do it."
Then freshman center Joel Bolomboy played the most crucial minutes of his short career, throwing down three dunks that cut the lead in half.
From there, Weber State slowly reeled in UND.
Bamforth buried a 3-pointer to tie the game at 74-74 with a little more than a minute to play. Bamforth then forced a turnover, and on the ensuing possession Tresnak dropped in the eventual game-winner with 19 seconds to play.
"We felt really confident at that point," Huff said of the 12-point lead, combined with its new fan base of Montana fans entering the arena for the second semifinal. "That just topped it off. Then they got a couple of big shots, and the game changed from there."
North Dakota had played its best game since making the transition to a Division I school in 2009, but in a losing effort.
"We did a lot of the little things we needed to do to have a chance," UND coach Brian Jones said. "It hurts because I thought we deserved to win. ... We're playing our best basketball right now, and we wanted to continue to play."
While UND waits for a possible CIT berth, the Wildcats remain on point for a chance at the NCAA Tournament.
"We'll be ready," Bamforth said. "No excuses."
