I was recently in Jack Main Canyon and visited Wilma lake, which all of the signs in the backcountry call Wilmer. I talked to the ranger, and he gave me a "Yeah, I know look" but said he had no idea why this was the case. I found an explanation online and figured I'd share it with others who might be curious.
This brought up another curiousity for me I hoped someone might have an answer for. I've noticed other errors on the Yosemite backcountry signs, for exampe the distance to Eagle Peak from the North RIm trail, and to Sentinal Dome via the 4mile trail from the valley, which the ranger explained was the distance from the original, long gone trail. My qestions ae, when were the signs first installed, and why have they never been corrected? Just wondering.
Anyway heres the story.
Wilma Lake was named after my mother, Wilma Seavey. (Seavey pass was named after her dad, Clyde Seavey.) The family story goes like this: My grandfather, Clyde Seavey, a member of the Sierra Club at the turn of the century (19th to 20th), was a friend of the cartographer or surveyor--or whoever worked for the feds and was in charge of mapping and naming geographical sites of interest. My grandfather was on a backpacking trip in the Sierra with this man, who was from New England and therefore had a New England accent.
My mother had just been born shortly before they took off on their trip into the back country of the Sierra. I guess the cartographer was mapping and naming sites as he went along. They came to a tarn and I suppose it needed a name. So the cartographer said to his assistant, "Let's call this Lake Wilma, after Clyde Seavey's new daughter." Only because he was a New Englander, he said, "Lake Wilmer," and his assistant, somehow unaware of this perculiarity in pronounciation, dutifully wrote down "Lake Wilmer".
And thus it stood, from 1912, as you point out, until 1956, when the spelling correction was made. The correction was made as a result of some letter-writing my parents did, to their congressman (John Baldwin, who served the East Bay area near San Francisco), and to whatever federal bureaucrats they needed to to get the spelling corrected. I remember they were quite proud of accomplishing this feat. Were they alive, they'd love to dial up your website and see your commentary.
Thanks again.
