Big Lou, Mountain summit in Chelan County, United States
Big Lou rises 5,200 feet above Icicle Creek Valley, standing at 7,763 feet elevation within the Alpine Lakes Wilderness of Washington State.
The mountain changed its name from Big Slide Mountain to honor mountaineer Lou Whittaker, twin brother of the first American to reach Mount Everest.
The summit register at Big Lou Mountain documents climbing achievements since 2002, marking the connection between mountaineers and this Cascade Range peak.
Access to Big Lou requires a 14-mile trek from Chatter Creek trailhead with 5,600 feet elevation gain, demanding strong navigation and endurance skills.
