Help identifying wood floor species

[aNYCdb]

Almost ready to refinish the floors at the cabin. I had assumed it was red oak, but after sanding some down I'm not sure (not a lot of grain). Any help confining the species would be helpful.

looks to be red oak because you can see some reddish tones on the sanded portions, also the grain pattern looks like oak. It also looks like it has been exposed to the weather, which will turn oak gray. Here's another test, though it may sound crazy.
When magnified, red oaks end grain looks like a pile of drinking straws and if you can get a small piece about 1/2 by 1/2 and 6 inch long, you can actually blow through the wood from the end grain side, but that would depend on how strong you can blow through the wood into a glass of water (so you can see the bubbles if they are there )
Wood identification is a pretty inexact science unless you have the tools and experience. You might get some help from a college nearby

Thanks, that's helpful. Looks like it is probably Red Oak after all.
