Access

Argosy Creek is accessed from ID-20 at Carey, Idaho. Look for the sign on the east end of town stating: Little Wood Reservoir 11.0 miles. See (E)(1) at page 261. Take this good paved road out of town passing homes, farms and ranches. The road turns to good gravel before reaching the turn for the reservoir. Continue on the main road. At 17.4 miles the road takes a sharp right turn and runs through the middle of a ranch. Continue through the ranch buildings for 6.8 miles to an unsigned junction just past a turn for another ranch. This road, shown on the map below, is FS-126. Most maps show it as a 4WD road but in fact it is a good road suitable for most vehicles when dry. Follow FS-126 as it skirts around the ranch property and works its way into upper Muldoon Creek for 2.5 miles where the road is wide enough to park. This spot is just past the confluence of Muldoon Creek and Argosy Creek.

Muldoon Creek is clogged with willows. Finding your way across the creek and then through the willows may turn into the crux of your climb. The best spot we found was 0.1 miles south of our parking spot. Good luck.

My GPS track for the Argosy Trio. Matt Durrant, Mike Fox and I hiked the loop portion clockwise. We skipped Peak 10500 but it can easily be climbed from the head of Argosy Creek.

Elevation profile. The great thing about combining all three peaks in one day is that once you make the first peak the up and down to the other peaks is minimal.
