About this page

Every line above is the first-ascent record as the open route catalogue carries it, shown in full so you can see exactly what we read this name from. We didn't research this history and we don't adjudicate it: first ascents are often shared and sometimes disputed, and a climb Ron Olsen was part of may be recorded here under someone else's name, or not recorded at all.

Something wrong? These records live in the open catalogue, and corrections made there reach this page on the next build.
