Anyone who climbs Shasta (14 162) in 2 days is a better man than I. Back in the 70s when I was in my 30s, it took me 5; took Trailways to Shasta City, hiked up in woods, camped on paper-co. land, on to glacier above Horse Camp (Sierra Club hut) & camped, on to summit & camped at fizzy hot sulfur spring on 14K' contour, 2 ascents from there (PM, dawn), back to camp at Horse Camp then down to Shasta City & Trailways motor coach back to San Francisco where I lived then. Great trip though got v. cold on summit; jacket over wool shirt wasn't enough in dawn wind. 100 in Redding.
Watched shadow of Shasta on W. sky at sunrise; had the same privilege from Gilman's Point on Kilimanjaro's crater rim where I managed to beat the sunrise, then on to Pt. Uhuru in Mar 73.
