I had a few questions after hiking in the Sierras for a week:
1. How do fish get into lakes when they can't swim into them from a
lower elevation? I saw a number of high Sierra lakes in which the
streams draining the lakes went down cliffs (ie, were waterfalls) or
went underground beneath massive piles of boulders. Either way, I
couldn't imagine how fish would get into the lakes originally.
2. What makes the alpine glow in the mountains?
3. Is there a formula for figuring out what % of the atmosphere
you're above when you're at a certain elevation? I was at 13,000 feet
on Saturday and I was curious how much oxygen there was in the air.
