Blair may have started a state title run of her own. Her older sister Sirene won four individual crowns from 2009 to 2013 before playing collegiately at San Diego State.
"This feels amazing. I wanted this so bad for our seniors," Blair said.
Blair shot a 68 in Monday's first round then followed that with a 69 in the final round. The Miners' standout was aware her closest rivals already had lost ground halfway through the second round.
"I told myself to just play my game. I wasn't as aggressive as yesterday, that's for sure," said Blair, who finished with a total of 137.
As for the conditions, Blair paid little regard to their influence, especially when the rain picked up again and she put a 50-yard approach shot on the 17th green.
"I try noy to let it bother me," Blair said. "I'm kind of used to it. In Utah, we play in a lot of bad weather."
Second to Blair individually was Westlake sophomore Alina Vannarath, while Blair's teammate Carissa Graft solidified Bingham's cushion over second-place Lone Peak by shooting a two-day total of 148 for third.
"I feel like, yeah, I really played well. But it was just a lot easier yesterday, a lot less rain," Graft said about the disrupting nature of, well, nature. "We get in the clubhouse [during the second delay of the day] and they were like, 'OK, it's safe to go back' about two minutes after we got here."
Graft finished second at the 2016 state tournament, while Blair was fourth. But having Blair jump her one year later didn't bother Graft.
"It didn't surprise me," Graft said. "She is a great golfer. It was more of a surprise how poor she played in the second round last year."
Corner Canyon defended its state championship, claiming the Class 4A state title by 17 shots over Alta at Meadowbrook Golf Course on Tuesday.
Emma Winfree, who tied for third place, led the Chargers with a two-day total of 171 points in the Stableford scoring system.
