What is this growth on this tree I saw at Great Basin National Park?

I saw this unusual growth jetting out of this tree when I was on the Sky Islands Forest Trail at Great Basin National Park. I am wondering what it is and how it got there?

    Those are sleeping bats whose feet got stuck in tree sap or pitch.
