The Bureau of Land Management oversees a little known but historically and ecologically important redwood park, the Headwaters Forest Reserve, which protects one of the most pristine groves of old growth redwoods, and the remains of an old timber ghost town, Falk, in the Elk River watershed.
The Headwaters has two access points, the Elk River Trailhead and the Salmon Pass Trailhead. The first, which includes interpretive signs about Falk, is open to the public year-round. The second is accessible by guided hike only. To arrange a guided walk for a small group that focuses on history. ecology or river science, accessible from Eureka or Fortuna, contact the BLM field office and ask for the Headwaters ranger.
