My fiancé and I made an overnight trek up Whitney on this past Thursday/Friday. Now, I’ve got a burning question... About a mile up the trail after leaving Whitney Portal, we heard a really deep “womping” noise. The noise came in sets of 5 or 6, and we’d hear it every 10 seconds or so. It sounded so deep it’s hard to believe it was a bird, but it could be. We heard it in the same area on our way up and down the trail. Any ideas??
