What changes at 9,000 feet
Air pressure here is about 72% of sea level. Leavening gases expand further, moisture evaporates faster and water boils around 194 °F, so cakes rise and sink, cookies spread and bakes dry out unless the recipe is rebalanced.

About 194 °F (90 °C), roughly 1 °F lower for every 500 feet of elevation.
Do I need to adjust yeast bread at 9,000 feet?
Yes, lightly: use about 25% less yeast, expect faster rises and add a little water if the dough feels stiff.
