What’s in a Name?

Twice the Fun: The headwaters of Big Creek begin high on the continental divide between Lost Ranger Peak and Mount Ethel. Big Creek forks to the east side of the divide and down into Big Creek Lakes (popular fishing spot with access from Walden) but the majority of the water continues its ride through the Mount Zirkel Wilderness where it eventually drains into the Elk River near the Red Dirt Trailhead.
