Zone 20A is a small, rugged slice on the Frank Church Wilderness fringe, surrounding the Big Creek and Yellow Pine area on the south side of the wilderness boundary. Elevations span from about 4,500 feet in the canyon bottoms to over 9,000 feet on the high ridges. The forest is mixed conifer—ponderosa, lodgepole, doug fir, with subalpine fir and whitebark pine at elevation. Old burns from the past two decades have left huge swaths of brushy regeneration that elk pile into. Payette National Forest covers most of the unit, with the Frank Church boundary running through the middle. Forest Road 340 from Yellow Pine is the main access and it's a long, slow, washboard drive from McCall—plan three to four hours one-way from McCall just to reach a trailhead. Yellow Pine is a tiny outpost with a single restaurant that sometimes serves; McCall is the supply town. No cell service. The non-wilderness portion has road access but the brushy burns require boots and patience to hunt well. The wilderness portion is foot or stock only and the country is genuinely remote. Bull quality is high; the pressure stays moderate because the drive in scares people off. A spot device is non-negotiable.
