Welcome to our blog! For the last 70 years, the Whittakers have been at the center of the mountaineering world. From Jim's first American ascent of Everest in 1963, to Lou's founding of RMI Expeditions in 1969, to Peter's foray into gear and apparel with Whittaker Mountaineering in the 2000s. 

Mountain Logic is the distillation of all that mountaineering knowledge into a series of blog posts. Whether you're looking for in-depth gear guides, mountaineering how-to's and history, or local info for Rainier National Park, we've got you covered.
