We are planning a long trip to Glacier, Yellowstone and Tetons this summer. A friend of a friend recommended that we hike near Mammoth lake where there are waterfalls. I can't seem to find it.
We did a similar trip last year, it was great! We saw lots of waterfalls in Glacier, but I don't remember a Mammoth lake. St Mary's and Virginia Falls were near enough to do in one hike and well worth it.
