Program Overview: On this backpacking trip to the Mono Pass area, you will camp two nights in a stunning spot nestled among whitebark pine (Pinus albicaulis) near the shores of Summit Lake (10,600 ft). The camp is surrounded by the talus slopes of Mt Gibbs and Mt Lewis where Sierra Nevada Bighorn sheep (Ovis canadensis sierrae) forage this time of year. Nearby are numerous ponds and meadows that provide ideal habitat for a few species that are only found in the Sierra Nevada of California — Yosemite toads (Anaxyrus canorus) and Sierra Nevada yellow-legged frogs (Rana sierrae). These four species are alpine specialists that are federally listed as threatened or endangered, and it is possible that you could see all of them during this trip.

A visit from Roland Knapp, a research biologist who has been working closely on the recovery of Sierra Nevada yellow-legged frogs for decades, is a highlight of the trip. Not only is Roland a biologist, but he is an incredible storyteller and teacher. By the time you leave, you will be peering in every puddle, pond and lake and noticing the rich diversity and drama unfolding in these alpine aquatic ecosystems. Roland will catch tadpoles, adults and subadults of these species so that you can see them up close.

You’ll also learn about Sierra Nevada bighorn sheep, the causes of the decline of the species and their road to recovery while hoping to catch a glimpse of them too. The whitebark pine and its relationship with the Clark’s nutcracker is another fascinating story that your naturalist will relate to you.

Other wildlife that are sometimes seen in the area include pika, marmot, Pacific treefrog, white-tailed jackrabbit, and many birds like prairie falcon, eagles, hawks, Clark’s nutcrackers and more.

This will be a small group with ample time to relax, learn and soak in the scenery. The alpine elevations are stunning. It will be helpful if you can spend time at high elevations before the start of the trip to acclimate.
