For a number of years, I have been envisioning a Pioneer High Line – a high elevation traverse from Craters of the Moon to Trail Creek Summit across the Pioneer Mountains, using a mix of sheepherder and hunter trails, elk paths, jeep roads and cross-country travel. On August 20-21, 2010, I spent two days solo doing the first 55-57 miles, at the end of which my wife Liz picked me up in Federal Gulch. I then came back on September 11 with my buddies Andy, Brad and Hank and completed the last 17-18 miles through the high peaks.
I’ll post a few pictures here, but head over to my picasa album for the full story.

The start of the Pioneer High Line, a 75 mile traverse from the sagebrush and lava of Craters of the Moon along the Pioneer Mountain crest to Trail Creek Summit above Ketchum, Idaho.

Looking south down Little Cottonwood towards Craters from Little Cottonwood Peak. The Great Rift is in the background. A nod to Robert Limbert, whose 1919 traverse of the Great Rift inspired him to protect Craters of the Moon.

Classic Idaho high country.

Dropping into Little Argosy, a trail-free opportunity.
The Peterson Ranch is visible in the background, 3400 vertical feet below.

Late summer monkeyflowers on Copper Creek.

The Little Wood high country, the wild heart of the Pioneers.

The upper reaches of the East Fork of the Big Wood from Grays Peak.
Johnstone Pass is in the background, the low point in the center ridge.

Hank Dart meets us at the top of Summit Creek. Chocolate milk and beer, and our ride home, are 4.5 downhill miles away. Until this point, we had three other trail users (all at the base of Hyndman Peak) and a Lava Lake sheepherder, in 70 miles of spectacular mountain country.
The High Line is everything I could have hoped – beautiful, wild, challenging.
