Larch Mountain, elevation 3,480 feet (1,060 m), is the highest free-standing peak in Clark County, Washington. (The andesite plugs Pyramid Rock and Sturgeon Rock are higher but are outcroppings on ridges of Silver Star Mountain.) It is laced by a network of gravel roads as part of the Yacolt Burn State Forest. The eastern flank of the mountain was scorched by a gigantic forest fire in September 1902 and subsequently experienced a massive rockslide that rendered that side mostly unvegetated. The southern section of the mountain is part of the Jones Creek Off-Road Vehicle recreation area. From the picnic area at the top, the view is west toward the Vancouver, Washington area and east to Silver Star. A minimum security prison/work camp is situated nearby, whose inmates construct fire roads, fire trails, maintain campgrounds and help fight fires in the area.
