Entries from Mountain “Guides”


A Tribute to Jim Whittaker

The mountains lost a legend this week.

To the climbing community, Jim Whittaker’s impact is immeasurable. To us at RMI and Whittaker Mountaineering, it was foundational.

Jim was Lou’s twin brother, and their shared love of the mountains shaped American alpinism in ways that still echo today.

Rest easy, Jim. We hope you and Lou are climbing something beautiful.

I went to the top of Rainier with RMI in June, 1979. It was one of the most memorable experiences of my life. Thanks to the Whittaker family for everything.
