100% hydration starter at high altitude

Toast

Does somebody know if an altitude of 5000ft would cause a 100% hydration sourdough starter to be thicker?

What I mean by this is that when I look at videos of bread making with a 100% hydration starter the starter seems to have the consistency of pancake batter and mine is less liquid.

Thanks.

My 100% hydration starter seems to be the same consistency here as it was at sea level. 

If anything usually the opposite is true. The lower humidity at higher elevations can cause dough to be drier and thicker.

I feed my starter at a ratio of 1.2.2 one part starter to two parts flour and water by weight; this is my understanding of a 100% hydration, also I use a 50/50 blend of bread and whole wheat flours.
