5:30 p.m. -- Finally got away from the ranch at San
Jose at 10:45 -- 5 pack mules, Lamb and Jose (the packer)
and I each on a horse; travelled continuously until
4:20 p.m., when made camp at Primeras Encinas, the
"first oaks", altitude by my barometer 6400 ft. All the
way here, from San Jose, is distinctly upper Sonoran,
though with varying associations. The dominant one all
the way is the greasewood association ( Adenostoma
fasciculatum) varied with dilutions of A. sparsifolium
above 5000 feet. On dry, surfacing slopes, there
are rather tall yuccas (baccata ?). A little cholla
cactus, just out of San Jose; lots of Yerba Santa of
a very narrow-leafed species; Rhus laurina and r.
ovata; Heteremeles in shaded ravines; and three
species of manzanita, two with narrow leaves and the
last 1000 feet, one that looks like mariposal(?). There
are a few four-leafed pinyons; and right here
are live oaks about a spring, making a
refreshingly green patch from a distance against
the grayish white mountain side. On the way
we passed the old placer workings of Socorro.
The rock all about San Jose is granite, with
a characteristic decomposed granite gravel
everywhere; then comes a belt of tilted schist
in great flakes and outcroppings; then here
is granite again.
From horseback, I could see little birdlife
as I came along. Near Socorro, I heard wren-tits,

Heteremeles appears to be an old or alternate spelling of Heteromeles but there was no way that I could find an "o" in what he wrote. as for "mariposal", I could not find a modern name that I could match with the "iposa" part that is reasonably readable and I simply guessed at the rest. He could be using a common name. Rhus laurina is now called Malosma laurina according to Califlora
