That's a White-headed Woodpecker nest cavity she's pointing at. White-headed Woodpeckers are excellent indicators of a good-functioning "dry pine" forest ecosystem. In this area (where the photo was taken) the dominant tree species is Ponderosa Pine. White-headed woodpeckers rely on a healthy Ponderosa pine forest for nesting and for food during the winter when insects are much less abundant (they eat the seeds out of the pine cones).
