This is an ATV trail descent from Coyote Valley Road (7S10)
to Big Pine.
From Coyote Valley Road (7S10)
head up and around the prominent Sugarloaf Mountain on Coyote Flat on 32E303. This becomes a wild, sandy descent back to the Owens Valley near Big Pine that is likely to leave your brake rotors a little hot.
Shannon Canyon is an alternate option about halfway down (~4.8 miles) which adds some rough singletrack to the descent.
