Nope. It definitely looks like Mammoth.
The current map has Mojave, Inyokern, Lone Pine and Bishop all marked with gray "Opening soon" marks.
The 2015 map has those same 4 as open, plus a new Red charger to the Northwest of Bishop. That's Mammoth, folks. To my knowledge, Tesla hasn't included non-Superchargers on that map. The Westin charger is a plain old slow charger.
For those that are really into driving the entirety of 395, there also appears to be a new charger to the east of South Lake Tahoe. That's likely Minden or somewhere similar. Makes sense as it would allow a worry free drive all the way from SoCal to Tahoe.
