Frost cracks are what we call the scar/defect in trees that have frozen and "popped" a bit. They do not heal up well. We timber cruisers find them in the higher elevations and will make volume deductions for the rot that occurs because of the wound. I have seen frost cracks on the more "thin barked" species--Grand Fir and Subalpine Fir.
Frost cracks are visible and are a scar or rough line running from the ground up in a pretty straight line. Of course, one needs to have a trained eye to see this. We see them more on the east side of the mountains, where the temperatures are colder. I'm thinking I've also seen it in Spruce and Lodgepole, but it was so long ago.
