This is from the MapQuest rendering, but I can't find this name anywhere in the OSM data. It should, of course, be Sierra Nevada ("sierra" is Spanish for "mountain range").

“Sierra Mountains” is a less common local name for the range, but you’re right, “Sierra Nevada” would be more appropriate for a map. MapQuest may be using their own custom layer or something for topographical features.

Wikipedia has 5 different sierra ranges.
not like we should import data from wikipedia though..

And none of those is called "Sierra Mountains". Was there a point to your comment?

I don't think the name is from OSM-data.
