Stadiums of the Pac-12

Look at Husky Stadium and Martin Stadium. Husky stadium holds twice as much but appears only slightly larger.

Reser have undergone two expansions since what it looks like how it was showing in Google Map

here is a more recent snapshot of Reser showing the newer east side and south end zone Reser Stadium

That graphic doesn’t take into account that several of those stadiums are multideck stadiums. Arizona, Sun Devil, Reser, Stanford, and Husky stadiums are all multi-deck stadiums, meaning that some seats are directly above lower deck seats.

Memorial, Folsom, Autzen, Rice-Eccles, Martin, the Rose Bowl, and the Coliseum all have single deck seating, meaning you enter the stadium and can move all the way up to the top of the stadium or all the way down to field level from that single entrance.

They’re all extremely old stadiums built during an era where that type of bowl was popular.

I always thought Stanford Stadium had an interesting setup with its sliver of seating missing from part of the bowl:

Jazzy’s right about the oval shape of all the California stadia being a remnant of the prevailing designs at the time.

However, you should note that although Ucla plays at the Rose Bowl and USC plays at the Colisseum, those really aren’t “on campus” places. It’s near enough to be moot for $C, but Ucla has to go over 20 miles to Pasadena for their “home” games.

Though it could be a bunch of ants colonizing. I’m not sure.
