This peak is not in the book.
Jack Chamberlain Peak is located on a long East-West trending ridge on the South Side of Chamberlain Basin. West Chamberlain Peak is at the West End of the ridge and East Chamberlain Peak is at the East End. What I know of this peak is based on the explorations of Dave Pahlas. Dave traversed the peak while in the process of climbing all 3 peaks. He reports that the peak is Class 3 via its East and West Ridges. See Dave’s trip report for the details. USGS Boulder Chain Lakes
