OK, so now you're just trying to get me confused. Well, I won't have it. It's going to be the Seattle engineer as the officially true story whether or not that's the way it really went down.

From Reginald H. Thomson's Wikipedia page:

"Reginald Heber Thomson (usually R.H. Thomson; 1856 – January 7, 1949) was a self-taught American civil engineer. He worked in Washington state, mainly in Seattle, where he became city engineer in 1892[1] and held the position for two decades. Alan J. Stein wrote that Thomson "probably did more than any other individual to change the face of Seattle" and was responsible for "virtually all of Seattle's infrastructure".[2]
Despite the scope of his work, no major portion of Seattle's infrastructure has ever carried Thomson's name. He was supposed to have been memorialized by the R.H. Thomson Expressway, proposed in 1960 but never built.[1][3]
Among his achievements were the railway route through Snoqualmie Pass,..."

So there we have the Snoqualmie Pass connection. And we all learned a little Seattle history...

Jon, I was mistaken. So, Leslie is right - USGS and Green Trails do show this peak as Thomson. But the latest Beckey CAG, Selected Climbs, and a few other guidebooks show this as Thompson. I've amended my comment above. How confusing! Aug 25, 2015

It's now corrected. Thanks a lot for the input. Aug 23, 2015
It's on the Green Trail Maps as Mount Thomson, just climbed it two days ago. I also read on summit post that it was named after R.H. Thomson, a seattle engineer. In the older versions of Fred Beckys Cascade Alpine Guide it was also mispelled but has since then been corrected. Aug 23, 2015

Jennifer -- do you have the source of the name, or an older reference to it?

I get confused looking this peak up on the Internet, as it gets listed a lot as Thompson. I don't have the Beckey guide handy, but I'll change the posted name if Beckey says so..

Thanks- Aug 22, 2015
USGS maps show 'Mount Thomson', and many guidebooks (including Selected Climbs in the Cascades and Beckey's Cascade Alpine Guide) call this 'Mount Thompson.' Aug 22, 2015

It is actually 9 miles from thee TH to the base of the climb (unless you do some mild bushwhacking through to one of the alternate routes wich shaves off miles but imo doesnt shave off any time. Jun 24, 2015
