Mammoth to June Traverse

2 days
All ages
1–4 people

Ski a classic! Tour the terrain between Mammoth Mountain and June Mountain. There's plenty of quality runs along the way.

Come ski this amazing 2 day, 14 mile traverse!

Your guide will arrange this skiing gem as a 2-day ultralight tour to allow plenty of time to milk the quality descents along the way. The route for this trip drops as often as conditions dictate to the north and east. It is here you’ll find all the powder stashes and sweet terrain. You’ll camp in the scenic and wild upper Deadman Creek drainage and finish with a summit of San Joaquin Mountain. The final descent is an impressive 4000′ to the June Lake area and the comforts of the Double Eagle Resort & Spa.

This tour makes for a perfect introduction to a multiday backcountry adventure. It’s ideal for people that only have the weekend to get out there and do it.

Here’s your itinerary for your awesome traverse!
Day 1

Meet your guide in the early morning at Mammoth Mountain. Check equipment and finalize packing. Then from Main Lodge you’ll skin up the closed road to Minaret Vista. From there the tour follows the San Joaquin Ridge north with spectacular views of the Minarets and the Ritter Range, as well as the headwaters of the Owens River to the east. Just before Deadman Pass, you’ll drop in to the northeast for a 1000′ powder run. From there you’ll climb back to the ridge to find another 1000′ run before finding camp in upper Deadman Creek.

Day 2

You’ll start your second day passing east of the imposing Two Teats on the way to the summit of San Joaquin Mountain. Descend right from the summit and drop down one of several options like Positive 1, the Hourglass, or the Negatives to Upper Yost Meadow. From there the plan is to descend gently via Yost Creek and then descend via the 4 Seasons run or possibly Devil’s Slide to finish at the Double Eagle Resort.

Congrats! Go celebrate the end of a fantastic traverse!

Viren Perumal

Viren was born in Thailand, and then settled in the Southeastern US, where, in his youth, he learned to climb and kayak whitewater. Viren holds a Masters degree in Biology/Eco-physiology. Since 1999, he has worked as a professional in almost every diverse aspect of the outdoor industry: raft guide, wilderness therapist, ski patroller, search and rescue worker, ambulance crew, outdoor educator, outdoor retail specialist, and biology researcher, and climbing guide. He is a insatiable learner and a master teacher. Viren got his first work as a climbing guide in 2000. He moved to the Sierra Nevada Mountains in 2004, where he fell in love with granite cracks and alpine peaks. Viren has guided rock, ice, and alpine ascents throughout the High Sierra as well as in the North Cascades, Canada, Alaska, Red Rocks, and South America. Viren earned AMGA Rock Guide certification in 2011, has completed an AMGA alpine guide training course, and completed AIARE Level 2 avalanche training in 2010. He also teaches the “AMGA Single Pitch Instructor” courses run by SMG. When not guiding, Viren trains and certifies other outdoor professionals in wilderness medicine through the Wilderness Medicine Institute of NOLS and he serves as Adjunct Faculty for the Prescott College Adventure Education Program.

Howie Schwartz

Howie is an international UIAGM & AMGA ski and mountain guide. He was fortunate to learn to ski as a toddler and he owned the first p-tex snowboard by Burton in 1987, where he hiked up the groomed runs of East Coast ski resorts. He discovered rock and alpine climbing in 1988 on a trip to the Tetons. The highlight was climbing the Grand Teton via the upper Exum Route with legendary climber and guide Chuck Pratt. Since then, climbing, skiing, and mountain guiding has taken him to many spectacular places, primarily to the Sierra Nevada, Alaska, and throughout the Alps – but also to places like Canada, Mexico, Peru, Bolivia, Argentina, Antarctica, and Thailand. He has logged numerous first ascents and ski descents in his personal and professional tenure. Howie has been guiding since 1993, and became one of the first 20 American guides to achieve the IFMGA professional credential in 2001. He was also the first and only American IFMGA guide to pass ski guiding exams on telemark equipment (though he shortly afterward went back to his fixed heel roots). With an outdoor education background, Howie got involved with teaching Avalanche Awareness Courses for a small Swiss-owned guide service in Crested Butte, Colorado in 1997. There he became one of the several collaborators to design the now ubiquitous AIARE avalanche course curriculum, and was the creator of the ” AIARE Decision Making Framework,” which the Level 1 & 2 courses are still based upon. Howie teaches Level 1-3 Avalanche Seminars and is involved with the Eastern Sierra Avalanche Center locally as a Board Member. Howie has also been an instructor/examiner for the AMGA Training and Certification Programs since 2000, working in all 3 disciplines and serving on the AMGA Technical Committee. He spent 6 years overseeing and developing AMGA ski mountaineering guide training and certification programs as Ski Discipline Coordinator. Lately, when not overseeing SMG’s operations, Howie has been getting back to what he loves most – climbing, skiing, guiding, & family. Howie also enjoys flatpicking guitar and can be seen jamming with string musicians throughout the Eastern Sierra. Howie’s wife, Karen, manages their unique mountain shop on Main Street in Bishop, California called Sage to Summit. They own a geodesic dome in Big Pine, but recently moved back to Bishop where they currently live with their amazing son Cosmo and dog Wheeler.

In addition, he is an avalanche and snowboard instructor, as well as a local ski patroller. Neil has climbed extensively in the United States as well as in South America, Mexico, Europe and Africa.
