High up in the spires of the Eastern Sierras, there lies a hidden and seldom visited gold mine perched on steep cliffs at 10,900 ft elevation. The Summit Mine is difficult to reach and is not for the fainthearted. To get there, you will have to follow a steep trail that threads its way across jagged granodiorite cliffs with breathtaking views of the old mining camp of May Lundy and Lake Canyon, more than 1,400 feet below.
