Thunder Creek is a small river and ascends a pretty, low-elevation valley of old cedar, hemlock and fir trees inside Ross Lake National Recreation Area and North Cascades National Park. _x000B__x000B_ The trailhead is at an elevation of only 1,200 feet, and the trail rises to only 1800 feet at our McAllister Creek turnaround point. Its easy walking along Thunder Creek, with glimpses of distant peaks through dark curtains of conifers. Cross numerous cascading creeks and gaze upon the silent faces of tumbled boulders cushioned in mosses and lichens. Look for the Pacific yew, distinct in its purplish-red bark and red seeds, and able to thrive in the deep shadows of old-growth forest. We will have early summer forest flowers in bloom too.
