The Avengers: Earth's Mightiest Heroes Wiki

The Nevada desert is the hottest region of Nevada state in the USA.

It is where the Cube is located where no one dared to enter there. Las Vegas is a good spot there where the Leader placed the Gamma Generator above Space Needle.

It is also where the battles are fought there. Like Hulk vs Hulkbusters, Absorbing Man,and two S.H.I.E.L.D. agents, Hawkeye and Black Widow are the examples.

In "Gamma World Pt.2", a dying Abomination was crawling in that desert before being found by Baron Zemo and the rest of the Masters of Evil in their intent to recruit him into their new team against the Avengers.
