Itinerary

Day One

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 Two

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. You can arrange to spend the night in the June Lake area or shuttle back with your guide to Mammoth.

Why should I go backcountry skiing?

Alpine peaks, open bowls, steep and secluded tree shots, cruisy, mellow runs — it’s all out there waiting to be explored in the backcountry.

It doesn’t matter your skill level, whether you’ve never backcountry skied or you’re seasoned on the slopes, skiing with a guide has its advantages. Your techniques will sharpen, you’ll learn how to navigate terrain safely, make smart decisions, and most of all, you’ll remain safe in unfamiliar terrain.

What about bad weather?

Mitigating avalanche risk is paramount for any excursion in the backcountry — that’s why it’s best to tour with a guide! Rest assured, your guide will set objectives that are attainable for the weather conditions on that particular day. Of course, inclement weather can always get in the way of backcountry skiing, but your guide will know the best course of action to take if the weather takes a turn.

On the rare occasion of truly bad weather, your guide will present you with suitable, safe alternatives. The most common practice is to move to a nearby location if it exists, or to reschedule your backcountry ski tour to a more favorable day.

If backcountry skiing is not possible on your scheduled day and no options presented are viable, you will be issued a full refund.

Do I need an insurance policy?

We highly recommended that you cover all your bases with emergency medical insurance. With medical insurance, if you have an accident or medical emergency on or off the mountain, you’ll avoid paying out of pocket for costly expenses. This covers everything from hospital treatments to emergency air transportation and more.

If you need assistance selecting the right insurance for your group, let us know and we will be happy to help!
