After passing the Neiderprum TH on my way to visit the mine and valley at the end of mine road, I decided to satisfy my curiosity about the trail going up Whitehorse Mountain.
Those who write the trail descriptions in the hiking guides must have written them years ago, because this trail is so badly overgrown starting at 2.5 miles that it probably won't be accessible much longer.
From the closed bridge at the end of mine road off Hwy 530, it is 1.2 miles to the Neiderprum TH. From there I hiked 1.7 miles up Whitehorse and gained 1,800' of elevation. I was hoping to reach the meadow where Neiderprum, a prospector, had his cabin. The destination was at an altitude of 3,200', but I was only able to follow the trail to 2,600' before it disappeared into thick, wet brush. My GPS said the trail continued in the direction I was going, but there was no sign of it whatsoever.
At least I had a good workout...
