Fern canyon, which does involve some hands on rock, is well worth the effort. Mark emerging from the birthing canal. Although short, the hike is sweet with several pools to soak in. Mark refilled his water bottles from the upper pool as did two guides we met so it is a viable source of water. We then crossed the river and made camp on the Texas side. We buzzard watched, ate brauts, drank tequila, read a book, took photos, and in general, had a good evening.
