Can anyone identify the mountain range?

I have done everything that I can think of to identify the mountain range depicted in the set piece behind the speaker in this TEDx talk:

At 6:35, on the right side of the screen, is the distinct silhouette of the mountain range that jarred my memory. I clearly remember seeing that mountain range as a kid, but I cannot identify it now.

I've googled every keyword combination that I can think of, and I've paged through hundreds of photos of mountain ranges and rock outcroppings, all to no avail. I know that this must be a famous mountain range. I don't know why I'm having so much trouble identifying it.

Any help here would be greatly appreciated. Thanks in advance.
