1. Three top seed teams made it to the fourth round. Yellowstone handled Arches, despite Arches hot shooting again beyond the arch. Great Smoky's cloud defense smothered Biscayne, and Yosemite's continued slow and steady climb outlasted Lassen's sometimes fiery offense.
2. Gettysburg has a strong defensive line, giving the Statute of Liberty's big woman trouble in the paint all night, while Everglades on both sides of the ball swamped Gulf Islands.
3. Grand Teton and Glacier played above the rim and clouds all game, with Glacier winning it on a deep jump shot. There was some controversy on the shot as some said it was taken from Canada and clearly out of bounds.
4. Finally, Denali's height, size and breadth off the bench proved too much for the scrappy but over matched Olympic.
