July 18, 1863: Sonora Pass
[Today] Hoffmann and I climbed a peak, perhaps over twelve thousand feet. The views are not so grand here as on the other trail, yet are fine. We had hundreds of peaks in sight with snow on them. The view was very wide, extending even across the plain—the coast ranges could be dimly traced, although 150 to 180 miles distant. A severe rheumatism came on and I was glad to get back to camp. Another cold night followed, but I slept warmer. Water boils at about 192° or 193°. John complains that the beans must be very dry—it takes from eight to ten hours to cook them—he can’t understand the low boiling point, nor understand the barometer sinking so low.
