Adjusting cookie recipes for high altitude When baking cakes, I often find that there are instructions for high altitude, which usually is just a matter of adding some extra flour.

I understand the concept of high altitudes having less atmospheric pressure, which then allows baked goods to rise more easily (too much), and thus the addition of flour.

However such alterations are not often provided with cookie recipes. What is a good way to know how to adjust cookies for high altitude, or if such an adjustment is even necessary?
There is a fairly detailed answer to this available here.

It appears that the answer depends a little on the type of cookie.  If you have a cookie that has a great deal of air in it you'll have the same problem as cakes do.  If you are working with a very dense cookie that can't really fall (since there isn't anywhere to go). At that point you're just down to watching baking times and temperatures, which are easier to monitor.
