Section Three Cover (and backcover) – Florence Hutchings
Florence Hutchings was "the first white woman to be born in Yosemite"
back in 1864. She really did hang out (at seven) with John Muir when he was there. OTL, she died at seventeen while leading a group of tourists around. Basically, a big rock fell on her.
Seeing someone born in Yosemite, and friends with John Muir, grow up to become involved in the conservation movement is really not all that much of a stretch – it'd be a surprise if she didn't
at least have a passing interest in such.
This is about the time that Tulare Lake starts getting drained – mostly because irrigation water is diverted away from it, but also because the big land owners in the San Joaquin Valley want to use
all that nice land currently underwater. This is the era where "improve land" and "drain it" are synonyms, after all.
I honestly don't know if there was much more than minor interest by any conservation group in saving the lake – it was pretty much gone by WWII on OTL. But it's quite possible that one person – here, Florence – could whip up a major movement towards preserving it. Now, how successful
this would be is another thing all-together – on the whole I'd say "not very." But for the purposes of a more interesting ATL, the dice fell double-six and Tulare Lake – the largest body of water in California – was saved and later became centerpiece of a National Park.
