With a unique, accordion-like construction this synthetic fill provides unending, resilient loft and retains your body heat's warmth even after sustained and repeated compression.

What’s in a Name?

Accessed from the Walden side of Mount Zirkel Wilderness via the Rainbow Lake Trailhead, Upper Slide Lake sits along Norris Creek at the Base of Mt. Ethel and just beyond Slide Lake. A giant secluded rock-slide waterfall and magnificent views of Mount Ethel ultimately lead you up to the Continental Divide and corresponding trail.
