Someone from the North Bay has petitioned to change the name of Mt. Diablo to Mount Kawukum. Mt. Diablo is, of course, the highest peak in the S.F. Bay area at a whopping 3849'. Quoting from the application:

The proponent, a resident of Oakley, suggests that the existing name is "derogatory and profane" and should be changed, preferably to one of the names used by the area's indigenous population. The proposed name reportedly means, "laughing mountain, everywhere seen," although the specific origin or linguistic derivation of the name is not known...

That points to the article "How Did Mount Diablo Get Its Name?" To me, the name sounds a bit Turkic, as if it might be a corruption of karakum.

The MSM report is here. They discuss how a group tried to change the name for similar reasons back in 1866.

I "climbed" Mt. Diablo sometime in either Winter 2000 or Winter 2001. I think the elevation gain was about 2000'. I had "climbed" Mt. Tam earlier in the day, for about 1500' of gain. I don't think I wrote up either trek, but from memory: the first part of the trail up Mt. Tam was fairly steep. When I found the trail I wanted there was a sign saying "Danger! Closed!" I took it anyway. There was a brief hailstorm up top, but no snow.

However, when I got to the lofty peak of Mt. Diablo there was - believe it or don't - about a foot of snow on the top. The steps to the observation hut were icy as were the railings and since I hadn't taken gloves that was a bit uncomfortable. Unfortunately the snow had not deterred the hordes who, like me, were somewhat shocked to see such accumulation in the Bay Area.
