You can't find rock shelters everywhere, but in a level forest I have seen upended root balls and stumps that would serve just as well.
The presence (or lack therof) of natural caves and rock shelters is highly dependent on the local geology. Natural shelters are extremely common in the generally highly stratified rocks of the Colorado Plateau. Likewise, in humid areas with limestone, caves are common. In other areas, with other geology, true caves may be rare to non existant. Even there, though, one can sometimes find large boulders that can be used with a small tarp to fashion a quick shelter.

As you point out, in forested areas, one can often find downed trees that will often provide good shelter. In forested areas with deep snow, tree wells will often work good. A few minutes work with a snow shovel can turn a tree well into a veritable palace.

In snow country a shovel is a key peice of gear. There are many small, lightweight designs to choose from. If one is traveling in avalanche country a really good shovel, along with probe and beacon is absolutely essential.
