Climbing and access information for this peak is found on page 175. The location discussed below is based on Brian Westphal’s research. The exact location of a number of formations located above Redfish Lake Creek have been subject to conjecture. This is primarily because there were no USGS quadrangles available when the formations were first climbed. Published April 2026
