Take the Whitney Portal Road west out of Lone Pine. Turn left onto Horseshoe Meadows Road. Continue up the road until you reach the trailheads.
Taken from a small offshoot meadow of Horseshoe Meadows. I watched this lenticular formation for a couple hours praying it would stay until sunset. Luckily as the sun set it lite up with glowing red light perfectly complimenting the bright green vegetation.
