$\begingroup$ so high enough in the mountains you would have more light oxygen and less heavy N2 and CO2? $\endgroup$

$\begingroup$ @HenningM. Maybe, Oxygen doesn't usually separate out in nature, Nitrogen displacement is usually a result of a temperature difference, cold Nitrogen displacing the warmer normal atmosphere including the Oxygen, Carbon Dioxide is naturally far denser than the rest of the atmosphere so in high concentrations it can separate and settle on rare occasions. Usually the atmosphere stays homogeneous and concentrated pockets of a single gas are the result of a local out-gassing event of some kind. $\endgroup$
