We parked at the end of Lost Horse Mine Road in Joshua Tree National Park... and will do the 2 mile hike out to the mine... then go up to the summit of Lost Horse Mountain... then go cross-country along the mountain's NW ridge and follow the ridge back to our car.

We started the hike by hiking east on the Lost Horse Mine Trail.

After hiking two miles we have arrived at the Lost Horse Mine... operated by Johnny Lang and a few others from 1894 until 1908.

From 1894 to 1908 the mine produced 10,000 ounces of gold and 16,000 ounces of silver.

At Point 5188 we have reached the Lost Horse Benchmark... here looking north to Ryan and Queen... east and SE to the Hexie Mountains... and south to part of the Little San Bernardino Mountains.

NW to Quail Mountain (the high point in the park) and the San Bernardino Mountains... and north toward the Wonderland of Rocks and Ryan Mountain.
