Remember that they've been studied now for nearly a century and the presentation can be updated but remains an early 20th century construct.
if you visited the Museum of Natural History the same applies - I like to visit it just for the 'old timey' atmosphere.
As to la Brea Woman - I'm hard pressed to imagine Chumash Indians being here as early as they've indicated.
There is another museum way out in Lancaster that was originally a retreat for a '30s college professor and the displays there are his making. They are basically a cross between fantasy and academic Victorianism....cute if you feel like a 100 mile drive into the desert.
(You can watch some nifty flying stuff out of Edwards while trying to figure out the insane street layout)
I omitted the entire point of my post...
This Montana find can be built up on today's standards and using modern displays, communications, and architecture...it should be something to look forward to.
It'd be real interesting to see if they come up with skulls that aren't immediately deemed to be related to the indians camped out there in the 19th cenury. (Ala La Brea Woman)
