Mount Anderson is a major mountain centrally located in the Olympic range and within Olympic National Park. Water from the Anderson massif drains into the Pacific Ocean, the Hood Canal, and into the Straight of Juan de Fuca. Mt Anderson was named in 1885 by Lt. Joseph O'Neal in honor of his commanding officer Major-General Thomas H Anderson. A climb of Mt Anderson involves a backpacking approach to Anderson Pass via either the West Fork of the Dosewallips River trail (12 miles), the East Fork of the Quinault River trail (18 miles), or from the Duckabush River trail (23 miles). From Anderson Pass, follow a path north uphill to the Anderson Glacier moraine. Ascend the glacier to Flypaper Pass, then descend onto the Eel Glacier to climb to the summit of Mt Anderson on its north side. Best time to climb is in the spring or early summer. Ice axe and crampons are essential gear.
