I'm not from the mountains.

Every time I go climbing, hiking, or backpacking in the mountains I lose all sense of depth perception. I can't tell by looking if a peak is 100 meters or a 1,000 meters above me. I have to stare hard and look for context clues (trees, if there are any).

And this has led to some hilarious problems.

1. If I spend enough time in the mountains, will my depth perception improve?
2. Are people who are born and raised in the mountains better at perceiving distances in the mountains?
